Abstract
Endometritis is a uterine inflammatory disease that causes reduced livestock fertility, milk production and lifespan leading to significant economic losses to the dairy industry. Mesenchymal stem cells (MSC) may act as an alternative for inefficacy of antibiotics and rising antibiotic resistance in endometritis. The present study aimed to cure the chronic endometritic buffaloes using allogenic adipose-derived MSCs (AD-MSC). AD-MSCs were isolated from buffalo adipose tissue and characterized by multilineage differentiation as well as MSC-specific markers. The in vivo safety and efficacy were assessed after infusion of AD-MSCs. In safety trial, cells were administered in healthy buffaloes via different routes (IV and IC) followed by examination of clinical and hematological parameters. In efficacy study, AD-MSCs treatments (IV and IC) and antibiotic therapy (ABT) in endometritic buffaloes were comparatively evaluated. AD-MSCs did not induced any immunological reaction in treated buffaloes. PMN count, CRP levels and VDS were significantly (p ≤ 0.05) reduced after AD-MSCs infusions in IV and IC groups and no significant difference was observed in antibiotic group. The IV group was marked with 50% absolute risk reduction in endometritis and 50% live calf births after artificial insemination in comparison with ABT group. Anti-inflammatory cytokines (IL4 and IL10) and anti-microbial peptides (PI3, CATHL4, LCN2 and CST3) expressions were significantly (p ≤ 0.05) upregulated in IV group. The calf delivery rate after the treatments in IV group was higher (50%, 3 calves) than the other groups (IC: 33.3%, 2 calves; ABT: 16.6%, 1 calf). In conclusion, the administration of AD-MSCs through IV route was found to be safe and efficacious for alleviating chronic endometritis in dairy buffaloes.

Abstract
Andaman and Nicobar Islands, a part of South-East Asia, is enriched with the presence of native breeds of livestock (cattle, pig, goat) and poultry. There are two native goat breeds, viz., Andaman local goat and Teressa goat in Andaman and Nicobar Islands. However, to date, the origin and genetic makeup of these two breeds have not been detailed. Therefore, the present study describes the genetic makeup of Andaman goats through analysis of mitochondrial D-loop sequence for sequence polymorphism, phylogeographical signaling and population expansion events. The genetic diversity of the Teressa goat was less compared to the Andaman local goat due to its sole presence on Teressa Island. Out of 38 well-defined haplotypes of Andaman goats, the majority of haplotypes belonged to haplogroup A followed by haplogroup B and haplogroup D. The result of mismatch distribution and neutrality tests indicated no population expansion event of haplogroup A and B. Finally, based on poor geographical signaling, we hypothesize that Andaman goats have been imported to these Islands either through multidirectional diffusion or unidirectional diffusion. We justify our hypothesis of multidirectional diffusion on the basis of observation of the haplotype and nucleotide diversity of Andaman goats. Simultaneously, the probability of unidirectional diffusion of goats in these islands from the Indian subcontinent in different spells of domestication events through maritime routes cannot be ignored.

Abstract
DNA synthesis and methylations are crucial during pre-implantation embryonic development, and are mediated by one-carbon metabolism of folates. Folates, transported into the cells via folate receptors (FOLR1 and FOLR2) and carriers (SLC19A1), are metabolized by various enzymes involved in folate-methionine cycle. However, the variations in temporal expression of folate transporters and folate-methionine cycle enzymes during pre-implantation embryo development is obscure. Thus, the present study aimed to investigate the differential expression of the genes for folate transporters and folate-methionine cycle enzymes. We also examined the expression of folate transport proteins in different pre-implantation development stages. Immature buffalo oocytes were matured in maturation medium followed by in vitro fertilization and culture at standard culture conditions. The temporal pattern of gene expression in buffalo, when compared to previous studies, indicated an inter-specific variation. The transcripts of some enzymes and folate transporters were significantly upregulated after zygotic genome activation. The transcripts as well as proteins for FOLR1, FOLR2 and SLC19A1 were present in oocytes and all the pre-implantation embryo stages. FOLR1 was present in the nuclei of different stages of developing embryos but not in the metaphase (MII) oocytes. As a result, the present study advocates the existence of active folate transport in buffalo oocytes and pre-implantation embryos. The data provided by the analysis of differential gene expression of folate transporters and metabolic enzymes would likely contribute to a better understanding of the role of folates in embryo development as well as advancements in assisted reproductive technologies.

Abstract
BACKGROUND & OBJECTIVES Japanese encephalitis (JE) is a major public health problem in India. The first outbreaks of JE have been reported from the North-eastern regions of Assam, particularly from the Lakhimpur district of Assam between July-August 1989. In Assam every year many people died due to JE. This study was performed to investigate the molecular epidemiology of JE in pigs in Lakhimpur district of Assam and the risk factors associated with causing Japanese encephalitis in pigs. This study will help to map out the endemic regions and to know where and when to apply the most control strategies towards the prevention and control of the disease. METHODS A total of 342 serum samples from pigs were collected from 10 organized and 20 unorganized farms from 9 blocks and recorded to age, sex and breed and tested by RT-PCR. Pig farms and the surrounding environment were studied for assessment of farm-level risk factors responsible for JEV infection in pigs. RESULTS Out of 342 samples tested for detection of the E gene of JEV, 14 samples were found to be positive with a prevalence rate of 4.09%. Age, sex and breed-wise higher cases were found in at the age group above 12 months, sex wise female and breed-wise local pigs. Pig farms less than 500 meters from risk factors like rice field, stagnant water source, wild bird exposure to farm and mosquito exposure at farm/ bite to pigs, found to be more numbers of JE cases. INTERPRETATION & CONCLUSION Molecular epidemiology of JE in pigs, and humans; positive at Lakhimpur recommend the need for uninterrupted surveillance of this virus in pigs specially those areas where pig population is more and all risk factors are present.

Abstract
Mesenchymal stem cell is a potent tool for regenerative medicine against control of incurable diseases in human and animals. Diabetes mellitus is one such condition marked with the blood glucose is high due to lack of insulin (INS) hormone secreted by the pancreatic cells. Rare, but sporadic, cases of dysfunctional pancreatic cells in goat as well as the promises of stem cell therapy as an off-the-shelf medicine prompted us to explore the potential of adipose-derived goat mesenchymal stem cells (AD-MSCs) to transdifferentiate into pancreatic islet-like cells. We isolated, in vitro cultured, and characterized the AD-MSCs by expression of MSC-specific markers and differentiation into multiple mesodermal lineage cells. The characterized AD-MSCs were in vitro transdifferentiated into INS-producing islet-like cells using a cocktail of glucose, nicotinamide, activin-A, exendin-4, pentagastrin, retinoic acid, and mercaptoethanol in 3 weeks. The transdifferentiated islet-like cells demonstrated the expression of pancreatic endoderm-specific transcripts PDX1, NGN3, PAX6, PAX4, ISL1, and GLUT2 as well as protein expression of pancreatic and duodenal homeobox 1 (PDX1), INS, and Islets 1 (ISL1). The islet-like cells also demonstrated the significant glucose-dependent INS release with respect to the course of transdifferentiation regime. The study envisaged to create the building material for basic research into mechanism of glucose homeostasis, which may pave road for developments in diabetes drug discovery and regenerative therapies.

Abstract
Background Leukemia inhibitory factor (LIF) is a multifunctional cytokine which plays multiple roles in different biological processes such as implantation, bone remodeling, and hematopoiesis. The buESCs are difficult to culture due to lack of proper understanding of the culture conditions. LIF is one of the important factors which maintain the pluripotency in embryonic stem cells and commercial LIF from murine and human origin is used in the establishment of buffalo embryonic stem cells (buESCs). The LIF from a foreign origin is not able to maintain pluripotency and proliferation in buESCs for a long term which is contributed by difference in the binding sites on LIF; therefore, culture medium supplemented with buffalo-specific LIF may enhance the efficiency of buESCs by improving the environment of culture conditions. The high cost of LIF is another major drawback which restricts buESCs research, thus limits the scope of buffalo stem cell use. Various methods have been developed to produce human and murine LIF in prokaryotic system. However, Buffalo leukemia inhibitory factor (BuLIF) has not been yet produced in prokaryotic system. Here, we describe a simple strategy for the expression and purification of biologically active BuLIF in Escherichia coli (E. coli). Results The BuLIF cDNA from buffalo (Bubalus bubalis) was cloned into pET22b(+) and expressed in E. coli Lemo-21(DE3). The expression of BuLIF was directed into periplasmic space of E. coli which resulted in the formation of soluble recombinant protein. One step immobilized metal affinity chromatography (IMAC chromatography) was performed for purification of BuLIF with ≥ 95% of homogeneity. The recombinant protein was confirmed by western blot and identified by mass spectroscopy. The biological activity of recombinant BuLIF was determined on murine myeloid leukemic cells (M1 cells) by MTT proliferation assay. The addition of BuLIF increased the reduction of MTT by stimulated M1 cells in a dose-dependent manner. The BuLIF induced the formation of macrophage like structures from M1 cells where they engulfed fluorescent latex beads. The recombinant BuLIF successfully maintained pluripotency in buffalo embryonic stem cells (buESCs) and were positive for stem cells markers such as Oct-4, Sox-2, Nanog, and alkaline phosphatase activity. Conclusions The present study demonstrated a simple method for the production of bioactive BuLIF in E. coli through single step purification. BuLIF effectively maintained buffalo embryonic stem cells pluripotency. Thus, this purified BuLIF can be used in stem cell study, biomedical, and agricultural research.

Abstract
Folate is essential for DNA synthesis and methylation via one-carbon (C1) metabolism during embryonic development. It is transported into the developing oocytes via folate receptors (FOLR1 and FOLR2) and transporters (RFC1) for utilization during embryo development. However, the role of folate receptors during pre-implantation stages of embryos is not well known. Thus, the present study aimed to investigate the expression of folate transport genes and proteins in mature oocytes and pre-implantation embryos; and the effect of FOLR1 knockdown in zygotes on blastocyst outcome. For this, Immature goat oocytes were matured in maturation medium followed by in vitro fertilization and culture at standard conditions. A group of zygotes was transfected with esiRNA against FOLR1 and in vitro cultured for blastocyst outcome assessment. The transcripts and proteins for FOLR1, FOLR2 and RFC1 were present in oocytes as well as all the stages of pre-implantation embryos. Immunofluorescence revealed the presence of FOLR1 in the nuclei of embryos but not in the metaphase (matured) oocytes. The knockdown of FOLR1 in embryos was effective and significantly reduced the blastocyst production rate. The present study demonstrates the existence of active folate transport in oocytes and pre-implantation goat embryos. FOLR1 is vital for pre-implantation embryo development and may aid in the progression by functioning as a transcription factor.

Abstract
Nicobari pig is reared by Nicobarese, a native tribal population of Andaman and Nicobar Islands. Nicobari pig has maintained its genetic identity due to geographical isolation. This communication is the first report on maternal inheritance of Nicobari pigs. DNA polymorphism data showed seven haplotypes. D-loop sequence information and mitogenome analysis were able to earmark Nicobari pigs to Asian clade. The domestication process of pigs and its expansion pattern help to understand human migration pattern. Based on this hypothesis, this communication elucidates the probable origin of Nicobarese. Earlier studies indicated that Nicobarese had genetic affinities to races distributed in China, Malaysia and Thailand. Our data on maternal inheritance of Nicobari pig correlates with the data on migration of Nicobarese. Moreover, we could establish a novel connection of Nicobarese with people of Northeastern parts of India, Philippines and Vietnam through phylogenetic signal and geographical provenance of Nicobari pig. We further concluded that migration of Nicobarese happened during Western route of migration (WRM) ∼4000 years before present. Therefore, we propose one wave hypothesis of peopling of Nicobar based on our study and existence of Ausrtroasiatic language, Mon-Khmer in these islands.

Abstract
Stephanofilariasis or humpsore is a chronic parasitic dermatitis of cattle. Various treatment regimens were attempted in the past but were found to be partially effective. Here, we claim a successful treatment regime using an FDA-approved macrocyclic lactone, a piperazine derivative, and an herbal preparation. Twenty-four cattle (18 affected and 6 unaffected) were selected and divided into Gr 1: positive control (infected without treatment; n = 6), Gr 2: treatment group (infected with treatment with ivermectin; n = 6), Gr 3: treatment group (infected with treatment with tri-model therapy including ivermectin, diethylcarbamazine citrate, and an herbal ointment, n = 6), and Gr 4: negative control (non-infected animals; n = 6). In Gr 2 and Gr 3, treatment to the ailing animals were given for 30 days. Lesion was significantly reduced in day 15 of post-treatment and completely healed on day 30 of post-treatment in Gr 3. Tri-model therapy recorded significant improvement in the surface area of the sore as compared to ivermectin administration alone. Antioxidants were increased and malondialdehyde (MDA) and cortisol concentrations were decreased significantly (p < 0.05) in Gr 3 than in untreated control group at day 14, 21 and 28. Histopathological changes in infected animals were characterized by parakeratotic hyperkeratosis along with presence of nucleated keratinocytes. There were infiltrations of polymorphonuclear cells specially eosinophils along with a few monomorphonuclear cells. Microfilarial organism was observed beneath the epidermis, which was surrounded by fibrocytes and infiltrated cells. In the tri-model-treated animal after recovery, the skin revived a normal architecture. Therefore, tri-model therapy has the potential to cure humpsore.

Abstract
Domestic ducks are of paramount importance as a cheap source of protein in rural India. Andaman local duck (ALD) is an indigenous avian genetic resource of Andaman and Nicobar islands (ANI) and is mainly distributed in Middle and Northern parts of these islands. Negligence has brought this breed on the edge of extinction necessitating immediate conservation efforts. Here, we report the genetic diversity, population structure and matrilineal genetic root of ALD. Partial mtDNA D-loop sequences were analyzed in 71 ALD samples and analysis revealed 19 polymorphic sites and 13 haplotypes. Estimated haplotype (Hd ± SD) and nucleotide diversity (π ± SD) were 0.881 ± 0.017 and 0.00897 ± 0.00078 respectively. The high genetic diversity of ALD indicates introgression of genetic material from other local duck breeds. In addition, it can be postulated that ALD bearing high genetic diversity has strong ability to adapt to environmental changes and can withstand impending climate change. Phylogenetic and network analysis indicate that ALD falls under Eurasian clade of mallard and ALD forms three clusters; one cluster is phylogenetically close to Southeast Asian countries, one close to Southern part of mainland India and the third one forms an independent cluster. Therefore, ALD might have migrated either from Southeast Asian countries which enjoy a close cultural bondage with ANI from time immemorial or from Southern part of India. The independent cluster may have evolved locally in these islands and natural selection pressure imposed by environmental conditions might be the driving force for evaluation of these duck haplotypes; which mimics Darwin’s theory of natural selection. The results of the study will be beneficial for formulating future breeding programme and conservation strategy towards sustainable development of the duck breed.

Abstract
Mastitis and metritis are two inflammatory diseases with high economic impact on dairy industry and farmers are losing revenues. Antibiotic treatment for these disease conditions typically achieve suboptimal outcomes. Moreover, emerging antibiotic resistance in mastitis and metritis worldwide has a severe effect on productivity, fertility, and lifespan of animals. A paradigm shift in treatment strategies is much needed for these animals. Attracting properties of mesenchymal stem cells may act as an alternative strategy for treating these diseases. In addition to their ability to differentiate into multiple types of cells, mesenchymal stem cells can orchestrate immune responses and modulate tissue microenvironments. In the present study, we evaluated the safety and efficacy of adipose tissue–derived mesenchymal stem cells (AT-MSC) for mastitis and metritis. A well-characterised adipose-derived stem cell line with 3–5 passages cells were used for treatment for these diseases. In a safety trial, mastitis- and metritis-infected cattle were administered with 1×106 cells of AT-MSC through different routes (local, IV, IV+local). Animals were clinically evaluated during 15 days of the experimental period and blood samples were collected for hemogram determination. The efficacy was checked under both invivo and invitro conditions. Invitro efficiency of AT-MSC was determined using a transwell plate experiment, in which AT-MSC were co-cultured with bacteria (Escherichia coli and Staphylococcus). Invivo efficiency was evaluated by administration of in 2mL (1×106 cells) of AT-MSC dose; then, somatic cell count (SCC) in milk of mastitic cattle and polymorphonuclear (PMN) cell count in cervical vaginal fluid (CVF) of metritic cattle were determined. Gene expression profiling of antimicrobial (cathelicidin, lipocalin, cystatin) and anti-inflammatory (IL-4, IL-6, IL-10) peptides were quantified in all groups: IV, local, IV+local, and control ATB (antibiotic). Allogenic AT-MSC did not induce any immunological rejection response in treated animals. A significant reduction of bacteria in CVF invitro when co-cultured with AT-MSC was observed. The PMN count was significantly reduced in CVF of the IV+local group. The SCC in milk of mastitic animals was decreased in the local (intramammary) group. Maximum expression of IL-6, IL-10, cathelicidin, lipocalin, and cystatin and angiopoietin genes were observed on Day 3 followed by Day 7 in the local group in case of mastitis. In metritis, expression of IL-6, IL-10, cathelicidin, lipocalin, cystatin, and angiopoietin were observed at Day 3 in the IV+local group. All mastitic and metritic cattle were completely and permanently cured within 30 days after treatment with mesenchymal stem cells. In conclusion, we provide initial evidence for the use of allogenic AT-MSC and their safety and efficacy to treat mastitis and metritis in dairy cattle.

Abstract
Germ cells are responsible for the propagation of live animals from generation to generation, but to surprise, a steep increase in infertile problems among livestock poses great threat for economic development of human race. An alternative and robust approach is essential to combat these ailments. Here, we demonstrate that goat putative embryonic stem cells (ESCs) were successfully in vitro differentiated into primordial germ cells and oocyte-like cells using bone morphogenetic protein-4 (BMP-4) and trans-retinoic acid (RA). Oocyte-like cells having distinct zonapellucida recruited adjacent somatic cells in differentiating culture to form cumulus-oocyte complexes (COCs). The putative COCs were found to express the zonapellucida specific (ZP1 and ZP2) and oocyte-specific markers. Primordial germ cell-specific markers VASA, DAZL, STELLA, and PUM1 were detected at protein and mRNA level. In addition to that, the surface architecture of these putative COCs was thoroughly visualized by the scanning electron microscope. The putative COCs were further parthenogenetically activated to develop into healthy morula, blastocysts and hatched blastocyst stage like embryos. Our findings may contribute to the fundamental understanding of mammalian germ cell biology and may provide clinical insights regarding infertility ailments.

Abstract
The present study sought to evaluate mRNA expression profiles in the cultured dermal fibroblasts of Tharparkar (zebu) and Karan-Fries (zebu, Tharparkar × taurine, Holstein Friesian) cattle in response to heat stress. Bioinformatics' analysis identified temperature-regulated biological processes and pathways. Biological processes overrepresented among the earliest genes induced by temperature stress include regulation of stress responses, protein repair, metabolism, protein transport, cell division, and apoptosis. The present microarray platform contains 51,338 synthesized oligonucleotide probes corresponding to at least 36,713 unigenes. A total of 11,183 and 8126 transcripts were differentially expressed with a fold change of ≥ 2 in Tharparkar and Karan-Fries cattle, respectively. Randomly selected real-time validation showed 83.33% correlation with microarray data. Functional annotation and pathway study of the differentially expressed transcripts or genes (DEGs) reveal that upregulated genes significantly (P < 0.05) affect protein processing and NOD-like receptor pathways (NLRs), while downregulated genes were significantly (P < 0.05) found to be associated with cell cycle, metabolism, and protein transport. Gene expression changes include activation of heat shock factors (HSFs), increased expression of heat shock proteins (HSPs), and apoptosis, while decreasing protein synthesis and another metabolism. These findings provide insights into the underlying mechanism of the physiology of heat stress in Tharparkar and Karan-Fries cattle. Understanding the biology and mechanisms of heat stress is critical to developing approaches to ameliorate current production issues for improving animal performance and agriculture economics in tropical climatic conditions. In conclusion, the present study indicates that heat stress differentially affects the expression of the significant number of genes associated with stress response, metabolism, apoptosis, and protein transport in dermal fibroblasts of Tharparkar and Karan-Fries cattle.

Abstract
Periconceptional folic acid is known to have a major role in the prevention of neural tube defects, leading to global recommendations for folic acid supplementation before and in early pregnancy. Maternal folate throughout pregnancy may have other roles in offspring health, including neurodevelopment and cognitive performance in childhood. Folate and folic acid (vitamin B9) act as a co-enzyme essential for single carbon metabolism, a network of pathways involved in several biological processes including nucleotide synthesis, DNA repair, and methylation reactions. In general, rapidly growing and multiplying cells require an adequate supply of folate. A primary deficiency of natural folate resulting in an increase of the total homocysteine concentration may be detrimental to the quality of the oocyte, subsequent fertilisation, embryogenesis, implantation, and fetal development. However, to date, folate-methionine metabolism and folate transport have not been studied in developing buffalo embryos. The present study details transcript expression for genes encoding key enzymes in the linked folate-methionine cycles in the ovary tissue, cumulus cells, immature oocytes, IVM oocytes, and pre-implantation embryos and also estimates the folate concentration in follicular fluid (FF) of buffalo. The FF was pooled and collected by aspiration of different sizes of surface follicles (2-8mm diameter). The total number of analysed samples was three, with different dilutions and estimation of folate in FF of buffalo done by chemiluminescence assay. Total RNA was extracted from oocytes, cumulus cells, ovarian tissue, and embryos produced from IVF. RT-PCR was performed to analyse the expression of folate-methionine cycle enzymes and folate transporters. Transcripts for all the enzymes of the folate-methionine cycle (i.e. SHMT, MTR, MTRR, MAT1A, MAT2B, GNMT, AHCY, CBS, and DHFR) and folate transporters (FOLR1, FOLR2) and reduced folate carrier (SLC19A1) were expressed in ovarian tissue, cumulus cells, oocytes, and pre-implantation embryos. Immunocytochemical analysis revealed FOLR2 and SLC19A1 protein expression on the plasma membrane and/or cytoplasm of the oocytes and embryos, and FOLR1 in the nucleus of pre-implantation embryos. The folate concentration in FF was 24ngmL−1. This is the first report to examine the concentration of folate in FF and revealed the identification of transcripts in different samples of buffalo species. The presence of these enzymes could have a profound effect on single-carbon metabolism within the ovary and pre-implantation embryo, therefore indicating that folate from FF is being disseminated through folate receptors within oocytes and embryos to participate in the folate pathway. This study advocates the necessity for examination of the result of folate supplementation throughout invitro embryo production for improving the quality and quantity of transferable blastocysts and subsequently live calf births in buffalo.

Abstract
The present study was carried out to isolate mesenchymal stem cells (MSCs) from adipose tissue of cattle (Bos indicus), characterise them, and apply them for the treatment of mastitis and metritis in the cow. Cattle MSCs were isolated from adipose tissue near the loin region of cow. Isolated adipose tissue was subjected to enzymatic digestion using 2% collagenase with agitation at regular intervals. The cells obtained after digestion were resuspended in cell culture flasks containing growth enriched medium and cultured under standard culture conditions. Alkaline phosphatase staining was used as one of the parameters to confirm cultured putative MSCs. Bovine Ad-MSCs were further characterised using real time-PCR by amplification of MSC-specific markers: CD73, CD90, and CD105 as positive markers and CD34, CD45, and CD79a as negative markers. Immunocytochemistry showed the presence of CD73, CD90, and CD105 on the cell surface. Three groups-control (C), local (L), and intravenous (IV)-with 6 cows suffering from mastitis were taken in each group and subjected to MSC transplantation through local and intravenous routes. Control group animals were subjected to antibiotic treatment only. Similarly, another three groups were taken with 6 cows in each group suffering from metritis. Post-transplantation wound healing, tissue repair, and reduction in inflammation were monitored for 26 days, at different time intervals; that is, after Days 1, 3, 7, and 15. Blood samples were also collected from animals at the same time intervals for real time-PCR. A similar examination was also done in metritis groups along with the analysis of the reduction in turbidity of cervical fluid at the abovementioned time intervals. Real time-PCR was performed to determine relative expression of genes for proliferative factors, anti-inflammatory cytokines, and antimicrobial peptides on cells isolated from blood collected at different time intervals. Gene expression in the local group of mastitis subjected to MSC injection was significantly higher than that of the IV and control group. The somatic cell count declined in both local and IV groups compared with the control group. Whereas the expression of the same genes in the IV group of metritis was significantly higher than that of the local and control groups of cows. The turbidity of cervical fluid and mucus was reduced in the IV group compared with the local group. In conclusion, we demonstrated the healing potential of MSCs in a cow model via MSC injection. Promising results were obtained in curing mastitis in both local and IV groups, whereas healing in the case of metritis was significantly higher in the IV group compared with both the control and local groups of cows. The study indicates the potential use of MSc for treatment of mastitis and metritis in cattle through wound healing and decreasing microbial infection.

Abstract
Andaman buffalo is an indigenous buffalo of Andaman and Nicobar Islands, India. Over the last decade, it has witnessed a rapid decline in population, necessitating its immediate characterization and conservation. The present study reports the complete mitogenome profile of Andaman buffalo which is 16,359 bp in length and comprised of 37 genes, including 13 protein-coding genes (PCGs), 22 transfer RNAs and two ribosomal RNAs. In addition, one A + T rich region (D-loop) was also present. A biasness towards A and T base was observed in all the genes. All the PCGs except ND6 were present on heavy strand. Start codons for all the 13 PCGs were ATN codon and abbreviated/truncated stop codons were observed in ND1, ND2, COX3, ND3 and ND4. The phylogenetic analysis revealed that the Andaman buffalo is closely related to buffalo from India and China. The results from this study will help in sketching the conservation plan of the threatened breed.

Abstract
Among stem cells, mesenchymal stem cells (MSC) are best suited for therapeutic purposes because of their immunomodulatory properties, ability to be isolated from adult animal at any stage, ease of propagation in the laboratory, and so on. The present study was carried out to isolate and characterise MSC from adipose tissue of mouse (Mus musculus), and to test their application for the treatment of fractured tibia bone in mouse. Cattle and buffalo MSC, already cultured and characterised in our laboratory, were used in the present study as xenogeneic MSC to observe the healing in mouse model. Murine Ad-MSC were isolated from mouse inguinal fat pad by enzymatic digestion method and cultured in growth enriching medium in standard culture conditions. To test the therapeutic potential of MSC, 24 mice were divided into 4 groups: control (C), allogeneic (A), cattle xenogeneic (CX), and buffalo xenogeneic (BX) with 6 mice (having tibial bone mechanical fractured) in each group, and had the corresponding MSC cells injected in the fracture area. The control group was not subjected to any kind of MSC treatment. Post-treatment, healing in all groups was examined for 36 days at different intervals (Days 1, 12, 24, and 36) via digital X-ray imaging. A bone healing score was assigned to each mouse per the protocol provided by RUST (Radiographic Union Scale in Tibial bone) fractures. The results of present study showed that murine Ad-MSC were positive for MSC-specific markers CD44, CD90, CD105, and negative for CD34 and CD45 via RT-PCR and immunocytochemistry. The Ad-MSC were also positive for the alkaline phosphatase staining. Statistical analysis, using Proc GLM (SAS Institute Inc., Cary, NC, USA), revealed that the bone healing was significantly different (P < 0.01) between group C (1.708 ± 0.059) and other groups [group A (2.125 ± 0.061), CX (2.167 ± 0.068), BX (2.250 ± 0.068)], suggesting that healing was greater in groups transplanted with MSC compared with control. However, healing between groups transplanted with MSC (A, CX, and BX) was not significantly different (P > 0.05). In conclusion, we have observed the healing potential of MSC in mouse model via allogeneic and xenogeneic MSC transplantation; the healing potential among the A, CX, and BX MSC groups was similar.

Abstract
Folic acid (vitamin B9) is the principal component of one-carbon (C1) metabolism in mammalian cells. It acts as a coenzyme in C1 unit transfer during nucleotide and amino acid metabolism. Therefore, it is unquestionably essential for the formation of thymidylate (TMP) for DNA synthesis and methylation, which is in turn crucial for post-implantation embryonic brain and nerve chord development. However, the role of folic acid in maturation of oocytes and subsequent blastocyst production is largely ambiguous in different mammalian species. The aim of this study was to investigate the effect of folic acid supplementation on expression of oocyte maturation markers and folate cycle enzymes in cumulus cells in addition to blastocyst development rate in goat. Immature oocytes were isolated from ovaries, and 1600 oocytes were matured in maturation medium (medium-199) supplemented with 0 (control), 50, 100, or 150 µM folic acid (Sigma Aldrich, India), comprising total 400 oocytes in each group in 5 replicates. The oocytes were in vitro fertilized and embryos were cultured for 7 days. Blastocyst rate was calculated in all 4 groups. Cumulus cells from matured oocytes from each group were analysed for the differential expression of oocyte maturation markers: PTX3, PTGS2, CTSB, and CTSS, and folate cycle enzyme transcripts MTR, MAT2A, ACHY, DHFR, and SLC19A1, by qRT-PCR. For statistical analysis, one-way ANOVA was used. The results of present study show that blastocyst rate was significantly higher (P ≤ 0.05) at 50 µM folic acid (21.4 ± 1.2%) compared with control (13.6 ± 0.4%), 100 µM (10.4 ± 0.34%), and 150 µM (7.4 ± 0.54%). However, there was no effect on the number of cleaved embryos among control (72 ± 0.21%), 50 µM (70.6 ± 0.58%), 100 µM (73.75 ± 0.31%), and 150 µM (73.02 ± 0.04%). The expression of the oocyte maturation markers PTX3 and PTGS2 was up-regulated, whereas that of CTSS and CTSSB was down-regulated (P ≤ 0.05), in the 50 µM group, but did not change (P ≤ 0.05) among the other groups. The expression of these genes did not change significantly among the other groups. The expression of genes of the folate cycle, MTR, MAT2A, ACHY, and DHFR, increased (P ≤ 0.05) by 5.7-, 3.6-, 2.2-, and 1.7-fold, respectively, at 50 µM, but did not change (P ≤ 0.05) among the other groups. The expression of SLC19A1 did not change significantly among all the groups. The results of present study show that the supplementation of 50 µM folic acid to the maturation medium results in increased maturation of oocytes, making them more competent for the blastocyst development. Up-regulation of transcripts of folate cycle enzymes at 50 µM might explain the increase in the blastocyst production rate, which further needs to be validated.

Abstract
Spermatogonial stem cells (SSC) form the basis of spermatogenesis and continuous fertility in male. Their meagre population in the testis is a hindrance in the in vitro study of biological activity of these cells. The objective of the present study was to isolate and characterise goat SSC and increase their number during in vitro culture by different methods. Two goat testes (3 to 4 months of age) were collected from the slaughterhouse and transported to the laboratory. The testes were washed and seminiferous tubules were collected and minced in the laminar flow hood. The seminiferous tubules were washed twice with PBS to remove spermatozoa and subjected to double enzymatic digestion (collagenase, 1 mg mL−1, hyaluronidase, 1 mg mL−1, trypsin, 0.05%, and DNaseI, 10 µg mL−1 for 45 min and second digestion with same set of enzymes except trypsin for 30 min). The isolated cells were filtered sequentially through nylon mesh filters of pore size 70 and 40 µm. The cells were plated on DSA-lectin coated dishes for 4 h and the unattached cells were cultured on a Sertoli cell feeder layer prepared by treating with mitomycin-C for 3 h. The cells were cultured in DMEM/F-12 supplemented with human recombinant growth factors (glial cell-derived neurotrpic factor, 10 ng mL−1, fibroblast growth factor FGF, 10 ng mL−1, epidermal growth factor, 20 ng mL−1), 10% fetal bovine serum, and antibiotics. The expression of pluripotency markers (Oct4, Nanog, Sox2) and SSC-specific markers (Thy1, GfrA1, and Uchl1) in the SSC colonies was determined by RT-PCR and immunostaining, after in vitro culture of 3 weeks. The SSC population was enhanced by differential plating, Percoll density gradient (on Day 1) and SSC passaging (by passaging SSC colonies on Day 20). The cells were tagged with GfrA1 antibody and their population was tested by flow cytometry. The SSC colonies started appearing after 7 days and continued to grow in size and number until 3 weeks. The SSC colonies were positive for the pluripotency markers Oct4, Nanog, and Sox2 by RT-PCR and immunostaining. The SSC were also positive for the SSC-specific markers Thy1, GfrA1, and Uchl1 by RT-PCR and immunostaining. Flow cytometry showed that the GfrA1-positive population in the SSC enriched by the differential plating was 11.23%, Percoll density gradient was 23.57%, and by passaging of SSC colonies, after picking and trypsinising with 0.05% trypsin, was 91.23%. In vitro culture of the SSC enriched by these methods also revealed that the number of SSC colonies appearing in the cells enriched by passaging was higher than the other methods. From the results of present study, we conclude that SSC are positive for markers of pluripotency and SSC-specific markers. The SSC population can be enhanced to a very high level following SSC passaging, which is an inexpensive method and does not require expensive instruments like fluorescence- or magnetic-activated cell sorting.

Abstract
This study aimed to understand the molecular characteristics of buffalo leukemia inhibitory factor (BuLIF) and the generation of a stably transfected COS-1_BuLIF cell line for its functional characterization. Cumulus cells, isolated from oocytes, were separated, and total cDNA was prepared. The BuLIF gene was ligated into the cloning vector pJET1.2/blunt and expression vector pAcGFP-N1 which was transfected into COS-1 cells and confirmed by qRT-PCR and Western blot. BuLIF was immunoprecipitated and evaluated through a MTT assay. qRT-PCR of STAT3 was performed. The multiple sequence alignment of BuLIF showed high similarity with sheep (98.77%) and cattle (96.62%) compared with other species. The BuLIF gene has an open reading frame of 609 nucleotides coding for 202 amino acids. BuLIF was integrated into the genome of COS-1 cells and resulted in the formation of dome-like secondary structures which are indicative of its functional role mediated through STAT3 proteins. In conclusion, this cell line is suitable for understanding LIF-mediated biological functions.

Abstract
Interferon tau (IFN-T) acts as a signaling molecule for maternal recognition of pregnancy (MRP) in ruminants. Aim of the present study was to identify various Buffalo Interferon tau (BuIFN-T) transcripts in buffalo trophoblast, phylogenetic comparison of these sequences with known mRNA sequences of buffalo, bovine, caprine and ovine and to express and purify the recombinant BuIFN-T (rBuIFN-T) isoforms. Following RNA extraction from trophectodermal cells, RT-PCR was performed using Ifn-t gene specific primers. 13 distinct cDNA variants encoding eight different BuIFN-T proteins were identified. BuIFN-T1a2 and BuIFN-T8 were expressed in prokaryotic expression system at 37 °C, 25 °C and 16 °C with 1 mM IPTG for 12 h and the recombinant proteins expressed at 16 °C were partially purified by Immobilised Metal Affinity Chromatography (IMAC). BuIFN-T isoforms have greater nucleotide and amino acid homology with caprine (98-100%, 96-100%), ovine (94-97%, 90-95%) and bovine (89.6-90.6%, 82-86%). These novel BuIFN-T isoforms contained pronounced nucleotide and amino acid sequence identity with one another (99.1-99.8%, 98-99%) but moderate sequence identity with previously identified buffalo IFN-T (90-92%, 82-86%). Solubility of expressed recombinant isoforms (rBuIFN-T1a2 and rBuIFN-T8) was highest at 16 °C. In conclusion, 13 distinct Ifn-t gene variants exist in trophectoderm of in vitro developed buffalo blastocysts that encode eight different proteins. rBuIFN-T1a2 and rBuIFN-T8 were successfully expressed in soluble form in Escherichia coli expression system at 16 °C with 1 mM IPTG and the resulting recombinant proteins were partially purified by IMAC.

Abstract
The present study was carried out for isolation and culture of adipose tissue-derived mesenchymal stem cells of goat (gADSC) and dogs (1 dog was suffering from hip dysplasia and another dog from paraplegia) and their characterisation with different markers. Adipose tissue of goat and dog were aseptically isolated and treated with collagenase for 2 h in a CO2 incubator. The enzymatic digested cells were filtered through a 41-µm filter and cells were resuspended in cell culture flask containing medium DMEM/F12, 10% fetal bovine serum, and 50 μg mL–1 gentamycin. In vitro-cultured ADSC were characterised by amplification of mesenchymal stem cell (MSC)-specific surface marker genes of CD44, CD29, and CD166 in PCR and by immunocytochemistry of MSC-specific marker of CD44. For in vitro chondrogenesis, ADSC at passage 3 were incubated in DMEM/F12 containing 100 nM dexamethasone, 1.25 μg mL–1 BSA, and 10 ng mL–1 BMP-4 ITS (insulin-transferrin-selenium) for 3 wk. Chondrogenic differentiation cells were confirmed by Safranin O staining and positive expression of chondrocyte-specific marker genes Aggrecan: primers F-TTGGACTTTGGCAGAATACC and R-CTTCCACCAATGTCGTATCC, and Collagen II: primers F-AACCCTGGAACTGACGGAAT and R-CTCACCCGTTTGACCTTTCG in PCR. Dog ADSC-derived chondrocytes were aseptically injected at 1 × 106 cells kg–1 of BW into dogs with hip dysplasia and paraplegia. Both dogs recovered well after 1 month of autologous transplantation and were able to move freely. Then, 10 dogs having massive wounds were injected with heterologous undifferentiated mesenchymal stem cells at 1 × 106 cells kg–1 of BW and all dogs were cured in an average of 20 days. Then, the paralyzed and fractured dogs were further treated with undifferentiated MSC at 1 × 106 cells kg–1 of BW and most of the dogs were cured properly. These findings may have implications for defining the physiological roles of ADSC in arthritis, some orthopaedic problems, joint regeneration, and neurological disorders and several new applications leading to novel therapeutic opportunities.

Abstract
Isolation of cells or stem cells from clinically dead animals may serve applications such as revival of the animal through somatic cell nuclear transfer (SCNT) or cryopreservation of their cells for a long period so that cells can be used in the future. Thus, combining isolation of cells from clinically dead animals and SCNT of germplasm of elite animals could benefit research into endangered or extinct species. In the present study, we tried to isolate and culture adipose-derived mesenchymal stem cells (ADSC) from a clinically dead dog. Adipose tissues were collected surgically from the abdomen of a dead dog after 3 h and processed tissues within 10 h of death. The isolated tissues were washed in 70% ethanol for 30 s and washed 5 times in Dulbecco’s PBS supplemented with 50 µg mL–1 gentamicin. These fat tissues were minced to very small pieces and washed in DMEM by centrifugation at 800 rpm for 3 min. The tissue pellet was subjected to enzymatic digestion (collagenase 1 mg mL–1 of Dulbecco’s PBS) at 37°C in CO2 incubator for 1 h, with intermittent shaking after every 10 min. The digestive enzyme was inactivated by equal volume of DMEM/F-12 supplemented with fetal bovine serum (20%) and centrifuged at 1000 rpm for 10 min. The pellet was resuspended in DMEM/F-12 with 10% fetal bovine serum and cultured at 1 × 106 cells mL–1 in 25-cm2 tissue culture flasks. The medium was changed after every 48 h. Mesenchymal stem cells (MSC) were observed under an inverted microscope after 6 days. These cells were subcultured and a confluent monolayer was obtained. We have already standardized the protocol of MSC culture and characterisation as we are treating wounded and paralysed dogs using these MSC in a pet clinic. Characterisation of MSC was performed with specific surface marker genes of CD44, CD29, and CD166 in PCR and by immunocytochemistry of MSC-specific marker of CD44. Differentiation of these MSC into osteogenesis and chondrogenesis were observed after 3 weeks. Chondrogenic differentiation was confirmed by positive expression of chondrocyte-specific marker genes Aggrecan F-TTGGACTTTGGCAGAATACC and R-CTTCCACCAATGTCGTATCC and Collagen II F-AACCCTGGAACTGACGGAAT and R-CTCACCCGTTTGACCTTTCG primer in PCR. The MSC were cryopreserved after 80% confluency was reached. The monolayer cells were scraped out from the culture flask and pelleted down. The pellet was resuspended in DMEM containing 10% DMSO and 20% fetal bovine serum. The number of cells was determined by trypan blue staining using an automatic cell counter and 105 cells mL–1 were added to a 2-mL cryogenic vial. The cryogenic vials were kept in a cryobox at –80°C for slow cooling. Then these vials were transferred to liquid nitrogen tanks after 12 h for long-term storage. We conclude that ADSC were successfully cultured from adipose tissue of a dog within 10 h of death and further subcultured under in vitro conditions. The cells could be used for SCNT to revive the dead animal and cryopreserve these cells for use in the future.

Abstract
The aim of our study was to optimize growth and induction parameters, for expression and large scale purification of functionally active buffalo interferon tau, and to study its possible impact on in vitro blastocyst development. The buffalo interferon-tau gene (BuIFN-T1) bearing gene bank accession No. JX481984, with signal sequence, was obtained through polymerase chain reaction (PCR) from bovine early embryos and was cloned into pJET vector. After being verified, the fragments without signal sequence, were inserted into the expression vector pET-22b and the recombinant plasmid was induced to express the recombinant protein in a prokaryotic expression system. The recombinant BuIFN-T was confirmed by SDS-PAGE and Western blot and subjected to three steps of large scale purification using His Affinity chromatography, Anion Exchange chromatography and Gel Filtration chromatography. The purified recombinant BuIFN-T protein was validated by mass spectroscopy analysis. To examine the effect of recombinant BuIFN-T protein on developmental competency of buffalo embryos, purified recombinant BuIFN-T protein was added to in vitro embryo culture medium (at concentration of 0, 1μg/ml, 2μg/ml, 4μg/ml) for 9days. Addition of recombinant BuIFN-T (2μg/ml) significantly improved the rate of blastocyst production, 45.55% against 31.1% control (p<0.01). Here we conclude that the recombinant BuIFN-T was successfully purified to homogeneity from a prokaryotic expression system and it significantly increased the blastocyst production rate in buffalo. These findings suggest a potential impact of IFN-T in promoting embryonic growth and development.

Abstract
Background In farm animals, there is no suitable cell line available to understand liver-specific functions. This has limited our understanding of liver function and metabolism in farm animals. Culturing and maintenance of functionally active hepatocytes is difficult, since they survive no more than few days. Establishing primary culture of hepatocytes can help in studying cellular metabolism, drug toxicity, hepatocyte specific gene function and regulation. Here we provide a simple in vitro method for isolation and short-term culture of functionally active buffalo hepatocytes. Results Buffalo hepatocytes were isolated from caudate lobes by using manual enzymatic perfusion and mechanical disruption of liver tissue. Hepatocyte yield was (5.3±0.66)×107 cells per gram of liver tissue with a viability of 82.3±3.5%. Freshly isolated hepatocytes were spherical with well contrasted border. After 24 hours of seeding onto fibroblast feeder layer and different extracellular matrices like dry collagen, matrigel and sandwich collagen coated plates, hepatocytes formed confluent monolayer with frequent clusters. Cultured hepatocytes exhibited typical cuboidal and polygonal shape with restored cellular polarity. Cells expressed hepatocyte-specific marker genes or proteins like albumin, hepatocyte nuclear factor 4α, glucose-6-phosphatase, tyrosine aminotransferase, cytochromes, cytokeratin and α1-antitrypsin. Hepatocytes could be immunostained with anti-cytokeratins, anti-albumin and anti α1-antitrypsin antibodies. Abundant lipid droplets were detected in the cytosol of hepatocytes using oil red stain. In vitro cultured hepatocytes could be grown for five days and maintained for up to nine days on buffalo skin fibroblast feeder layer. Cultured hepatocytes were viable for functional studies. Conclusion We developed a convenient and cost effective technique for hepatocytes isolation for short-term culture that exhibited morphological and functional characteristics of active hepatocytes for studying gene expression, regulation, hepatic genomics and proteomics in farm animals.

Abstract
UNLABELLED Mammary gland is an exocrine and sebaceous gland made up of branching network of ducts that end in alveoli. Milk is synthesized in the alveoli and secreted into alveolar lumen. Mammary gland represents an ideal system for the study of organogenesis that undergoes successive cycles of pregnancy, lactation and involution. To gain insights on the molecular events that take place in pubertal and lactating mammary gland, we have identified 43 differentially expressed proteins in mammary tissue of heifer (non-lactating representing a virgin mammary gland), and lactating buffaloes (Bubalus bubalis) by 2D-difference gel electrophoresis (2D-DIGE) and mass spectrometry. Twenty one proteins were upregulated during lactation whereas 8 proteins were upregulated in heifer mammary gland significantly (p<0.05). Bioinformatics analyses of the identified proteins showed that a majority of the proteins are involved in metabolic processes. The differentially expressed proteins were validated by real-time PCR and Western blotting. We observed differential expressions of certain new proteins including EEF1D, HSPA5, HSPD1 and PRDX6 during lactation which have not been reported before. The differentially expressed proteins were mapped to available biological pathways and networks involved in lactation. This study signifies the importance of some proteins which are preferentially expressed during lactation and in heifer mammary gland. BIOLOGICAL SIGNIFICANCE This work is important because we have generated information in water buffalo (B. bubalis) for the first time which is the major milk producing animal in Indian Subcontinent. Out of a present production of 133milliontons of milk produced in India, contribution of buffalo milk is around 54%. Its physiology is somewhat different from the lactating cows. Buffalo milk composition varies from cow milk in terms of higher fat and total solid content, which confers an advantage in preparation of specialized cheese, curd and other dairy products. Being a major milk producing animal in India it is highly essential to understand the lactation associated proteins in the mammary gland of buffalo. In the present investigation our attempt has been to identify new protein evidences which are expressed in lactating buffalo mammary gland and have not been reported before. The findings reported in the present study will help in understanding the lactation biology of buffalo mammary gland in particular and the mammary gland biology in general.

Abstract
Interferon tau (IFN-tau) is known as maternal pregnancy recognition factor in ruminants. IFN-tau not only acts as a signalling molecule of pregnancy recognition but also performs various functions for successful implantation and pregnancy establishment. The aim of the present study was to produce recombinant buffalo interferon-tau (BuIFN-Tau) and observe if it has any effect on in vitro embryo development. The BuIFN-Tau gene was obtained through polymerase chain reaction (PCR) from hatched buffalo blastocysts and was cloned into pJET cloning vector. Screening of the recombinant colonies gave 8 distinct buffalo IFN-tau isoforms, out of which the predominant buffalo IFN-t tau1 isoform (gene bank accession number JX481984), was subcloned into expression vector pET22b without signal sequence. The recombinant plasmid was induced to express the recombinant protein by isopropyl b-D-1-thiogalactopyranoside. Analysis of the products of recombinant BuIFN-tau without signal sequence by SDS–PAGE revealed a new 20-kDa protein coinciding with the molecular weight of IFN-tau as reported earlier in literature. The purified recombinant BuIFN-tau was confirmed by Western blot using anti-HIS antibody and was subjected to three steps of large-scale purification using HIS affinity chromatography, anion exchange chromatography, and gel filtration chromatography. Finally, a relatively pure histidine-tagged recombinant protein, which had a purity of at least 90%, was generated as confirmed through SDS. The concentration of recombinant BuIFN-tau was 1 mg mL–1 by Bradford assay. The purified recombinant BuIFN-tau was used as supplement of the culture medium for IVF early buffalo embryos at the following concentrations: control, 1, 2, and 4 µg mL–1. Sixty oocytes each in 4 groups (with 20 oocytes/drop in three replicates for each group) were used for in vitro maturation. After 24 h, the matured oocytes were incubated with in vitro capacitated sperm cells for 18 h; thereafter, the presumptive zygotes were cultured in IVC medium supplemented with 0, 1, 2, or 4 µg mL–1 of the purified recombinant BuIFN-tau. The experiment was repeated 3 times. The data were analysed using SYSTAT 7.0 (SPSS Inc., Chicago, IL, USA) after arcsin transformation of percentage values. The differences were analysed by one-way ANOVA followed by Fisher's least significant difference test. Out of 3 concentrations of recombinant BuIFN-tau, the 2 µg mL–1 concentration significantly promoted the rate of blastocyst development, 45.55% against 31.1% (control; P < 0.01). Blastocyst development rate for low and high concentrations was 29.97% and 10.18% respectively. It is concluded that the addition of 2 µg mL–1 of recombinant BuIFN-tau enhances the blastocyst development rate in buffalo, and hence there is some evidence that BuIFN-tau has not only a role in maternal recognition of pregnancy but also in embryonic development.

Abstract
Stem cells have potential for therapeutic application. Continuous repair of ovarian surface epithelium following folliculogenesis and ovarian carcinoma suggests the presence of stem cells in ovarian epithelial cells. In vitro gametogenesis in livestock will result in large numbers of oocytes production from a single ovary, resulting in faster multiplication of superior germplasm of livestock species, treatment of infertile animals, and conservation of endangered species. The present study was conducted with the objective of in vitro differentiation of putative ovarian surface epithelial stem cells into oocyte-like structures in goat model. Ovary samples of 1- to 2-year-old goats were collected from slaughterhouse. The surface of the ovary was gently scraped using sterile blunt scraper to isolate ovarian surface epithelial stem cells. These scraped cells were cultured in DMEM/F12 supplemented with 20% FBS for 3 weeks in 5% CO2 at 37°C with maximum humidity. The cultured stem cells were characterised for stemness by RT-PCR and immunostaining for Oct4, Sox2, and Nanog genes after 3 weeks. These putative stem cells were in vitro differentiated spontaneously to oocyte-like structures in DMEM/F12 medium and characterised for premeiotic markers by RT-PCR and immunostaining for VASA, DAZL, and STELLA genes. Results of this study provide evidence for the presence of putative stem cells with pluripotent characteristics in the ovarian surface epithelium. The cultured cells were found to be round in shape, with a high nucleus to cytoplasm ratio under inverted microscope, and found positive for stem cell markers of Oct4, Sox2, and Nanog genes. A total of 66 oocyte-like structures were produced from 12 ovaries. These oocyte-like structures were nearly similar to oocytes produced in vivo, both morphologically and in molecular gene expression. The oocyte-like structures were also found positive for premeiotic markers of VASA, DAZL, and STELLA genes by RT-PCR and immunostaining. From this study, we concluded that the ovarian surface epithelial cells have putative stem cells which can be in vitro differentiated into oocyte-like structures in goat. These oocyte-like structures need further characterisation of their surface membrane, more molecular markers, and following their developmental potential. These oocytes can help for multiplication of elite germplasm, curing infertile animals, and saving endangered species.

Abstract
The aim of this study is to generate parthenogenetic embryos from chemically activated in vitro matured caprine oocytes and to study the in vivo developmental potency of such embryos. The parthenogenetic embryos (2-8 and 16 cells to morula stage) were surgically transferred in 26 recipients. Pregnancy in recipients following embryo transfer was monitored by ultrasonography. The recipient aborted a foetus on day 34 post transfer. Sexing of parthenogenetic foetus showed a single band of amelogenin gene indicating female cell DNA. Microsatellite analysis revealed that the recipient has not contributed genetically to the parthenogenetic foetus confirming the identity of aborted foetus of parthenogenetic origin. The authors believe that this is the first authentic report on in vivo development of parthenogenetic foetus in Capra hircus.

Abstract
Nanog is a homeodomain containing protein which plays important roles in regulation of signaling pathways for maintenance and induction of pluripotency in stem cells. Because of its unique expression in stem cells it is also regarded as pluripotency marker. In this study goat Nanog (gNanog) gene has been amplified, cloned and characterized at sequence level with successful over-expression in CHO-K1 cell line using a lentiviral based system. gNanog ORF is 903 bp long which codes for Nanog protein of size 300 amino acids (aas). Complete nucleotide sequence shows some evolutionary mutation in goat in comparision to other species. Protein sequence of goat is highly similar to other species. Overall, gNanog nucleotide sequence and predicted protein sequence showed high similarity and minimum divergence with cattle (96 % identity/4 % divergence) and buffalo (94/5 %) while low similarity and high divergence with pig (84/15 %), human (81/23 %) and mouse (69/40 %) indicating evolutionary closeness of gNanog to cattle and buffalo. gNanog lentiviral expression construct was prepared for over-expression of Nanog gene in adult goat fibroblast cells. Lentiviral expression construct of Nanog enabled continuous protein expression for induction and maintenance of pluripotency. Western blotting revealed the expression of Nanog gene at protein level which supported that the lentiviral expression system is highly promising for Nanog protein expression in differentiated goat cell.

Abstract
The present work was carried out to investigate the global gene expression profile to search differentially expressed candidate transcripts between parthenogenetic and in vitro-fertilized (IVF) caprine morula. For this study, total RNA was isolated from diploid parthenogenetic and IVF embryos, and complementary DNA was synthesized. Microarray and relative real-time polymerase chain reaction analysis were performed to check global gene expression profile and validation, respectively. According to the microarray analysis, the total number of upregulated (UR) and downregulated (DR) genes was 613 and 220, respectively in diploid parthenogenetic morula as compared with IVF morula. The number of genes showing about two-, two- to five-, five- to 10-, 10- to 20-, and above 20-fold UR and DR genes was 147, 229, 122, 59, and 56 and 94, 73, 18, 13, and 22, respectively. Five UR genes validated (PTEN, PHF3, CTNNB1, SELK, and NPDC1) and all of them were significantly higher in parthenotes, which was in accordance with microarray results, whereas the expression of DR (AURKC and KLF15) genes were downregulated in parthenotes as observed in microarray results but the difference was not significant (P < 0.05). In conclusion, our findings demonstrate differential expression of a large number of genes in parthenotes compared with IVF embryos, which may be the reason for aberrant parthenogenetic embryo development in caprine species.

Abstract
The maternal pregnancy recognition factor interferon tau (IFN-τ) is expressed in multiple isoforms in all pecoran ruminant species. Interferon-τ, as the first pregnancy signaling molecule, performs a significant role in implantation as well as establishment of pregnancy. Due to low reproductive efficiency of buffalo compared with bovine and IFN-τ being the key molecule of reproductive physiology in ruminants, the objective of our study was framed to identify the various IFN-τ transcripts in buffalo embryonic trophoblast cells, to know their relative abundance to identify the relatively predominant isoform, and lastly to clone and express it in a heterologous host. Following total cellular RNA extraction from primary trophectodermal cells, RT-PCR was performed using gene-specific primers designed against known bovine IFN-τ sequence. Cloning of the amplified product and screening of the recombinant colonies gave 13 distinct cDNA variants that encoded for 8 distinct buffalo IFN-τ isoforms. These buffalo IFN-τ isoforms have a greater nucleotide and amino acid homology with caprine IFN-τ (98–100% and 96–100%) than ovine (94–97% and 90–95%) and bovine (89.6–90.6% and 82–86%), respectively. The novel buffalo IFN-τ isoforms showed pronounced nucleotide and amino acid sequence identity with one another (99.1–99.8% and 98–99%) but only moderate identity with previously identified buffalo IFN-τ (90–92% and 82–86%). All the 13 transcript sequences were accepted in GenBank. Out of 8 isoforms, buffalo IFN-τ1 has been found to be the relatively predominant, which was subcloned into expression vector pET 22b without signal sequence from pJET cloning vector and expressed in competent BL21 (DE3) Escherichia coli strain. Expression of the recombinant protein in soluble form was induced by isopropyl β-D-1-thiogalactopyranoside (0.1 mM) at 30°C for 6 h. The recombinant BuIFN-τ obtained was confirmed by Western blot using anti-HIS antibody. A new 20-kDa protein was detected coinciding the molecular weight of IFN-τ reported earlier in literature. In conclusion, the current study revealed that there are 8 different isoforms of IFN-τ that are expressed in trophectodermal out-growths during early pregnancy of buffalo. Predominantly found isoform IFN-τ 1 was expressed in pET 22b vector, and recombinant soluble protein was confirmed by Western blot.

Goat ADSCs were isolated from goat adipose tissue by the enzymatic digestion method and were enriched by filtering through a 41-μm filter. Thus, filtered cells resuspended in a cell culture flask containing growth enriching medium and cultured in 5% CO2 in air at 38.5°C. Goat ADSCs were characterised by amplification of mesenchymal stem cell specific markers i.e. CD29, CD34, CD44, CD90, and CD166 as positive markers and CD41 and CD71 as negative markers. Immunocytochemistry of mesenchymal stem cell was also carried out with specific markers CD44 and CD90. Goat ADSCs were further characterised by in vitro differentiating them into osteocytes, chondrocytes, and adipocytes. For in vitro differentiation of gADSCs into osteocytes gADSCs were supplemented with conditioned medium i.e. DMEM containing fetal bovine serum (FBS), dexamethazone, B-glycerol phosphate and L-ascorbic acid. Osteogenic differentiation was confirmed by positive Alizarin red S staining and amplification of Osteopontin and Collagen I genes. For differentiation into chondrocytes cells, gADSCs were incubated in DMEM/F12 containing dexamethazone, ITX, BMP-4, and FBS for 21 days. Differentiated cells were confirmed by positive Safranin O staining and expression of chondrocytes specific Collagen III and Aggrecan genes. For adipogenesis, gADSCs were incubated with DMEM/F12 containing FBS, dexamethasone, and ITX and differentiated cells were confirmed by positive Oil Red O staining and amplification of adipocytes specific genes i.e. LPL, PPRγ and PPRα. For in-vitro differentiation gADSCs into pancreatic islets-like cells on the third or fourth passage gADSCs were incubated in conditioned medium containing serum-free DMEM/F12 medium with glucose (17.5 mM) in the presence of nicotinamide (10 mM), activin-A (2 nM), exendin-4 (10 nM), pentagastrin (10 nM), retinoic acid (10 μM) and mercaptoethanol (20 μM). The in vitro differentiation gADSCs into pancreatic islets-like cells was confirmed by amplification of pancreatic endoderm specific genes i.e. igf-1, sst, ngn3, pdx-1, isl-1, c-kit, thy-1, and Glut-2, and no expression was detected for above endoderm specific genes in undifferentiated gADSCs. Pancreatic islets-like cells were further characterised by immunostaining and Western blotting of Pdx-1, insulin, and Islets-1 specific protein. It could be concluded that gADSCs was differentiated into different lineages and secretory insulin was produced from pancreatic islets-like cells.
