Abstract
Japanese encephalitis (JE), a neglected tropical zoonotic disease prevalent in south-east Asian and western pacific countries, caused by the flavivirus JE virus (JEV), has a dearth of electrochemical point-of-care (PoC) diagnostic tools available to manage endemic breakouts. To overcome this, we have developed a screen-printed carbon electrode (SPCE) immunosensor for rapid PoC detection of JEV nonstructural 1 (NS1) antigen (Ag), found circulating in serum of infected individuals using a smartphone based portable "Sensit" device. The modification of SPCE surface with JEV NS1 antibody (Ab) was confirmed via observation of globular protein structures via scanning electron microscopy (SEM), increase in electrode surface hydrophilicity via contact angle measurement and decrease in current via differential pulse voltammetry (DPV). The fabrication and testing parameters were optimized based on highest current output obtained using DPV. The SPCE was tested for detection limit of target JEV NS1 Ag ranging from 1 fM to 1 μM, which was determined as 0.45 fM in spiked serum. The disposable immunosensor was also found to be highly specific in detecting JEV NS1 Ag over other flaviviral NS1 Ag. Finally, the modified SPCE was clinically validated by testing 62 clinical JEV samples using both a portable miniaturized electrochemical "Sensit" device coupled with a smartphone and a laboratory-based potentiostat. The results were corroborated with gold-standard RT-PCR and showed 96.77% accuracy, 96.15% sensitivity, and 97.22% specificity. Hence, this technique may further be developed into a one-step rapid diagnostic tool for JEV, especially in rural areas.

Abstract
The present study evaluated healing potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) and BM-MSCs-conditioned medium (BM-MSCs-CM) for acute and subacute injuries in the rabbit peripheral nerve injury model. The regenerative capacity of MSCs was evaluated in 40 rabbits divided into eight groups, four groups each for acute and subacute injury models. BM-MSCs and BM-MSCS-CM were prepared by isolating allogenic bone marrow from the iliac crest. After inducing sciatic nerve crush injury, different treatments consisting of PBS, Laminin, BM-MSCs + laminin, and BM-MSCS-CM + laminin were used on the day of injury in the acute injury model and after ten days of crush injury in the subacute groups. The parameters studied included: pain, total neurological score, gastrocnemius muscle weight and volume ratio, histopathology of the sciatic nerve and gastrocnemius muscle, and scanning electron microscopy (SEM). Findings indicate that BM-MSCs and BM-MSCS-CM have augmented the regenerative capacity in acute and subacute injury groups with a slightly better improvement in the subacute groups than the animals in acute injury groups. Histopathology data revealed different levels of regenerative process undergoing in the nerve. Neurological observations, gastrocnemius muscle evaluation, muscle histopathology, and the SEM results depicted better healing in animals treated with BM-MSCs and BM-MSCS-CM. With this data, it could be concluded that BM-MSCs support the healing of injured peripheral nerves, and the BM-MSCS-CM does accelerate the healing of acute and subacute peripheral nerve injuries in rabbits. However, stem cell therapy may be indicated during the subacute phase for better results.

Abstract
Lateral flow assays (LFAs) are one of the most economical, point-of-care (PoC) diagnostic assays that exploit the colorimetric properties of gold nanoparticles (AuNPs). Up to the best of our knowledge, no rapid antigen-based LFA exists for Japanese Encephalitis Virus (JEV) detection. Herein, we have reported a novel portable sandwich-type LFA for on-site detection of the non-structural 1 (NS1) secretory protein of JEV. In-house JEV NS1 antibodies (Abs) were generated and labelled with AuNPs as immunoprobes. A glass fibre membrane conjugate pad was soaked with AuNPs-Ab solution, while the JEV NS1 Ab and anti-rabbit IgG 2° Ab were coated as the test and control lines, respectively, on a nitrocellulose (NC) membrane. Different layers of the LFA were fabricated and various parameters were standardised for optimum colour intensity development. JEV negative serum samples spiked with JEV NS1 Ags (linear range - 1 pg ml-1 to 1 μg ml-1) were applied onto the sample pad and the intensity of the red colour developed on the test line increased with increasing concentration of Ag. The visual limit of detection (LOD) determined from the LFA was 10 pg ml-1, which corresponded to the LOD determined by the graphical data obtained from ImageJ software and the Colorimeter smartphone application. Furthermore, the colorimetric based immunosensor showed minimal non-specific detection of other closely related flaviviral NS1 Ags in the spiked serum, provided a rapid result within 10 min, showed storage stability up to a month at 4 °C, successfully detected the JEV NS1 protein in clinically infected pig serum samples, and hence, may be developed into a PoC screening diagnostic kit for JEV.

Abstract
BACKGROUND The wound healing potential of canine bone marrow-derived mesenchymal stem cells (BMSCs) was evaluated in the excisional wound of streptozotocin-induced diabetic rats. RESEARCH DESIGN AND METHODS Xenogenic BMSCs were collected aseptically from the iliac crest of healthy canine donors under general anesthesia. Full-thickness experimental wounds (20 × 20 mm2) on the dorsum of forty-eight adult healthy Wistar white rats. The wounds were assigned randomly to three treatment groups: PBS (Group A) or BMSCs (Group B) injected into the wound margins on days 0, 7, and 14 or BMSCs (Group C) injected into the wound margins on days 7, 14, and 21 post-wounding. The degree of wound healing was evaluated based on macroscopical, hemato-biochemical, histopathological, and histochemical parameters. RESULTS The results indicated granulation tissue formation with reduced exudation and peripheral swelling in the treatment groups compared to the control group A. Similarly, the degree of wound contraction was significantly higher in groups B and C animals than group A on days 14 and 21 post-wounding. The transplantation of BMSCs resulted in early drying of wounds, granulation tissue appearance, and enhanced cosmetic appearance. CONCLUSION The histopathological, histochemical, and gross findings suggested the therapeutic potential of xenogeneic mesenchymal stem cell therapy in managing diabetic wounds.

Abstract
The caprine mesenchymal stem cells (MSCs) derived from fetal adnexa are highly proliferative. These cells possess tri-lineage differentiation potential and express MSC surface antigens and pluripotency markers with a wound-healing potential. This present study was conducted to compare the immunomodulatory potential of caprine MSCs derived from the fetal adnexa. Mid-gestation caprine uteri (2-3 months) were collected from the abattoir to isolate MSCs from amniotic fluid (cAF), amniotic sac (cAS), Wharton's jelly (cWJ) and cord blood (cCB), which were expanded and characterized at the 3rd passage. These MSCs were then stimulated with inflammatory cytokines (IFN-γ and TNF-α) to assess the percentage of inhibition produced on peripheral blood mononuclear cells (PBMCs) proliferation. The percentage of inhibition on activated PBMCs proliferation produced by cWJ MSCs and cAS MSCs was significantly higher than cCB and cAF MSCs. The relative mRNA expression profile and immunofluorescent localization of different immunomodulatory cytokines and growth factors were conducted upon stimulation. The mRNA expression profile of a set of different cytokines and growth factors in each caprine fetal adnexa MSCs were modulated. Indoleamine 2, 3 dioxygenase appeared to be the major immunomodulator in cWJ, cAF, and cCB MSCs whereas inducible nitric oxide synthase in cAS MSCs. This study suggests that caprine MSCs derived from fetal adnexa display variable immunomodulatory potential, which appears to be modulated by different molecules among sources.

Abstract
Models using in vitro produced buffalo embryos and in vitro cultured uterine epithelial cells (UECs) may be useful in understanding the intricacies of embryo-uterine cross talk. In the present study, buffalo UECs were obtained from slaughterhouse derived non-gravid uterus. UECs monolayer was treated with steroids (10pg/ml estradiol for 24h and 3.14 ng/ml progesterone for another 5 days). In vitro produced buffalo blastocysts were co-cultured over steroid treated UECs monolayer and at 72 h of co-culture, embryo attachment rate was higher in UECs treated with steroids (71.86% vs. 26.55%) while no attachment was observed on plastic surface. Naturally hatched or assisted hatched blastocysts were co-cultured over UECs monolayer treated with 3.14ng/ml progesterone (P4), or without any treatment for 72 h and the effect of co-culture on the expression profile of adhesion related biomolecules was analyed in UECs and blastocysts. Cultured UECs and blastocysts cultured in embryo culture media were considered as control. It was observed that the expression of MUC1 in UECs was significantly (p < 0.05) higher in control group than treatment groups. The relative mRNA abundance of integrins and osteopontin was significantly (p < 0.05) higher in UECs and blastocysts of treatment groups than control group. Expression of IFN-τ was significantly higher (p < 0.05) in embryos co-cultured with UECs than other treatment groups. It can be concluded that P4 supplementation is required for the modulation of adhesion molecules and co-culture of blastocysts and UECs together affect the expression of adhesion molecules both in blastocyts and in UECs.

Abstract
The COVID-19 outbreak, caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), was first identified in China, and it has quickly become a global threat to public health due to its rapid rate of transmission and fatalities. Angiotensin-converting enzyme 2 (ACE2) has been identified as a receptor that mediates the entry of SARS-CoV-2 into human cells, as in the case of severe acute respiratory syndrome coronavirus (SARS-CoV). Several studies have reported that ACE2 expression is higher in Leydig, Sertoli and seminiferous ductal cells of males, as well as in ovarian follicle cells of females, suggesting possible potential pathogenicity of the coronavirus in the reproductive system. Higher ACE2 expression in the human placenta and reports of vertical transmission of SARS-CoV-2 among clinical cases have increased the relevance of further studies in this area. This review focuses on the interaction between SARS-CoV-2 and the ACE2 receptor and speculates on the mechanistic interplay in association with male and female reproductive physiology. In addition, based on the available literature, we discuss the alleged sex differences in terms of the infectivity of SARS-CoV-2, which is claimed greater among males, and further explore the physiological role of ACE2 and 17β-oestradiol for the same.

Abstract
Intraspinal administration of allogenic bone marrow-derived mesenchymal stem cells (aBM-MSC) along with supportive therapy can be recommended as a therapeutic strategy for managing neural defects associated with non-deviating vertebral compression fractures in canine patients. Percutaneous technique described in this communication is a non-invasive and efficient method that can be used for transplanting stem cell into the target site without the need of any imaging or guidance system. Simplified implantation protocol that can be applied in the field level.
Stem cell therapy has been extensively evaluated for its potential in managing neuronal diseases and disorders. The present study was performed to evaluate the therapeutic potential of allogenic bone marrow-derived mesenchymal stem cells (aBM-MSC) for the management of neural defects associated with vertebral compression fracture (VCF) in canine. Six clinical cases presented with the history of neural defects secondary to non-deviating VCFs were included in the present study. All the animals were subjected to detailed clinical, radiological, and haematological investigations and observations were recorded. The neurological defects in each case were graded based on routine neurological examination. The aBM-MSCs were isolated, cultured, and characterized as per ISCT criteria from the bone marrow collected from healthy dogs presented for elective surgery. The prepared cell suspension containing aBM-MSC at 3rd passage was utilized for transplantation in the clinical cases of VCF. Following the intraspinal administration of aBM-MSC, the dogs were treated with methylcobalamin and gabapentin orally throughout the study period. Improvement was evaluated on the basis of a detailed neurological examination. Significant improvement in locomotor status and sensory functions was observed in all the cases. Findings of the present study suggest that intraspinal administration of aBM-MSCs along with supportive therapy can be recommended as a therapeutic strategy for managing neural defects associated with non-deviating VCFs in canine patients.

Abstract
Classical Swine Fever (CSF) is an extremely infectious and deadly disease of pigs and wild boars caused by the CSF virus (CSFV) which is a member of the Pestivirus genus and the family Flaviviridae. This study was designed to detect the permissibility and replication of CSFV in mesenchymal stem cells (MSCs) monolayer derived from Porcine Wharton's jelly. Porcine Wharton's jelly MSCs (pWJ-MSCs) were ex vivo expanded and propagated for more than 81 generations and third passage pWJ-MSCs were characterized as per standard criteria i.e., growth characteristics, trilineage differentiation potential and molecular characterization for pluripotency and stem cell surface markers. Porcine WJ tissue samples found negative for CSFV by RT-PCR test were processed further for the isolation of pWJ-MSCs and CSFV was propagated over the characterized pWJ-MSCs monolayer. No cytopathic effect was observed, which was consistent with non-cytopathic nature of CSFV. The replication of CSFV in pWJ-MSCs was affirmed by RT-PCR and demonstration of viral antigen in the cytoplasm of virus infected cells by immuno-staining technique. In total, three different CSFV isolates were propagated in pWJ-MSCs. Primary pWJ-MSCs permitted CSFV replication to good titer. To the best of our information, this is the first ever report of isolation of CSFV in pWJ-MSCs.

Abstract
The objective of this study was to compare the therapeutic potential of canine bone marrow derived mesenchymal stem cells (BM MSCs) augmented mesh scaffold for wound healing potential in guinea pig before and after cryopreservation. Bone marrow aspirate was obtained from healthy dogs and culture was expanded in vitro. MSCs augmented mesh scaffold were cryopreserved for 30 days and then used for therapeutic purposes. Both fresh and frozen thaw MSCs augmented mesh scaffold along with fresh MSCs were used for therapeutic purposes in guinea pig. No significant (P > 0.05) difference was observed in population doubling time (PDT) among fresh and frozen thawed BM MSCs. Both fresh and frozen thawed BM MSCs expressed cell surface markers (CD73, CD90, and CD105), and did not express CD34 as was confirmed by Immunocytochemistry and Real-Time Polymerase Chain Reaction. The fresh and frozen thawed BM MSCs successfully differentiated into osteogenic, chondrogenic and adipogenic lineages. Therapeutic results revealed that the percent wound contraction on day 14 was more than 65 % for the mesh augmented with MSCs as well as freshly injected MSCs group as against 33-34 % in the control group. Healed wound quality parameters viz. surface epithelium, neovascularization, and collagen characteristics were better for the mesh augmented with MSCs as well as freshly injected MSCs group compared to the control group. No significant difference was noted among fresh and frozen thawed BM MSCs group and fresh MSCs injected group. Thus, it is concluded from this study that canine BM MSCs augmented mesh scaffold both fresh and frozen thaw can be used for quality wound healing.

Abstract
Background & objectives: The lower recovery of competent oocytes in buffalo species limits the commercialization of in vitro embryo production technology in field condition. In this context, pre-maturation of small follicle (SF)-derived oocytes with meiotic inhibition may be a promising alternative to obtain more number of competent oocytes. Thus, the present study was conducted with an objective to enhance the developmental potential of less competent SF-derived buffalo oocytes. Methods: All the visible follicles (used for aspiration) from buffalo ovaries were divided into two categories: large follicle (LF) (follicles having diameter ≥6 mm) and SF (follicles of diameter <6 mm). The competence of LF and SF oocytes was observed in terms of brilliant cresyl blue (BCB) staining, cleavage rate, blastocyst rate and relative gene expression of oocyte and blastocyst competence markers. Thereafter, less competent SF oocytes were treated with 0, 12.5, 25, 50 and 100 mM doses of roscovitine (cyclin-dependent kinase inhibitor) to enhance their developmental potential. Results: Based on parameters studied, LF oocytes were found to be more competent than SF oocytes. Pre-maturation incubation of SF oocytes with roscovitine reversibly arrested oocyte maturation for 24 h to ensure the proper maturation of less competent oocytes. A significantly higher number of BCB-positive oocytes were noted in roscovitine-treated group than SF group. Cleavage and blastocyst rates were also higher in roscovitine-treated group. The relative messenger RNA expression of oocyte (GDF9, BMP15, GREM1, EGFR, PTGS2 and HAS2) as well as blastocyst (INF-τ, GLUT1 and POU5F1) competence markers was significantly greater in roscovitine-treated group relative to SF group. Again, on comparison with LF group, these parameters depicted a lower value in the treatment group. Interpretation & conclusions: The findings of this study has revealed that pre-maturation incubation of SF-derived oocytes with 25 μM roscovitine can improve its developmental competence and thus can be utilized to get maximum number of competent oocytes for better commercialization of in vitro embryo production technology in buffalo.

Abstract
The present study describes an immunocytochemistry (ICC) assay with self-raised hyperimmune sera and a Baby Hamster Kidney-21 (BHK-21) cell line infected with Porcine Sapelovirus (PSV). Sapelovivus/IVRI/SPF-c-6/2015 strain Indian PSV was isolated from the porcine IBRS-2 cell line and investigated for growth on non-porcine cell lines. After two passages, PSV was successfully grown in BHK-21 and produced the same cytopathic effects as in IBRS-2 such as shrinking of cytoplasm, rounding of cells and detachment of cells from the surface of flask within 24 h. For raising of hyperimmune sera, PSV was grown in IBRS-2 cell line up to the required volume and purified by ultracentrifugation. With self-raised hyperimmune sera in laboratory rats, ICC was performed in BHK-21 cells infected with PSV. Positive signals consisted of large granular aggregates of virus in the cytoplasm near the nucleus, suggesting that PSV can infect cell lines other than those of porcine origin.

Abstract
The objective of the present study was to develop a rapid, simple, specific and sensitive Taqman-based real-time PCR assay for porcine sapelovirus (PSV) detection. Specific primers and probe were designed from the five untranslated regions (UTRs) of the viral genome. The detection limit of the real-time PCR was 102 copies. The specificity of the Taqman real-time PCR assay was evaluated using other animal viruses and nuclease free water as a negative control. Strong fluorescent signals were obtained only in the detection of PSV real-time PCR and conventional RT-PCR were preformed simultaneously on 90 faecal samples. Based on conventional RT-PCR study 17.7% (16/90) of the faecal samples were positive for PSV. Whereas 21 of 90 samples (23.3%) were positive by real-time RT-PCR. The results showed that real-time PCR was more sensitive than the conventional RT-PCR assay. In conclusion, the Taqman real-time PCR assay for detection of PSV developed, herein, is sensitive, specific, and reliable. This assay will be useful for clinical diagnosis, epidemiological, and pathogenesis studies.

Abstract
This study was conducted to characterize canine bone marrow-derived mesenchymal stem cells (BMSCs); in vivo tracking in mice, and therapeutic evaluation in canine clinical paraplegia cases. Canine BMSCs were isolated, cultured, and characterized in vitro as per International Society for Cellular Therapy criteria, and successfully differentiated to chondrogenic, osteogenic, and adipogenic lineages. To demonstrate the homing property, the pGL4.51 vector that contained luciferase reporter gene was used to transfect BMSCs. Successfully transfected cells were injected around the skin wound in mice and in vivo imaging was done at 6, 12 and 24 hr post MSCs delivery. In vivo imaging revealed that transfected BMSCs migrated and concentrated predominantly toward the center of the wound. BMSCs were further evaluated for allogenic therapeutic potential in 44 clinical cases of spinal cord injuries (SCI) and compared with conventional therapy (control). Therapeutic potential as evaluated by different body reflexes and recovery score depicted significantly better results in stem cell-treated group compared to control group. In conclusion, allogenic canine BMSCs can serve as potent therapeutic candidate in cell-based therapies, especially for diseases like SCI, where the conventional medication is not so promising.

Abstract
The aim of the present study was to see the impact of L-Carnitine (LC) on lipid biosynthesis and metabolism of buffalo embryos, and post thaw blastocyst survivability. In vitro fertilized (IVF) embryos were derived from slaughterhouse derived COCs and cultured in different doses of LC i.e. 0, 1 mM, 1.5 mM, 2 mM starting at 48 h post IVF. Blastocyst rate was significantly (p < 0.05) higher in 1.5 mM group than control and 1.0 mM group. Lipid content was measured indirectly by fluorescent intensity of lipid droplets after Nile red staining, and it was lower (p < 0.05) in treated than control groups. CPT1B, DGAT2 and DGAT1 mRNA expression was up regulated (p < 0.05) while AMPKg1 expression was down regulated in 1.5 mM and 2 mM groups compared to other groups (p < 0.05). mRNA expression of GLUT1, OCT4 and IFN-tau was higher (P < 0.05) in 1.5 mM group than the control group. Expression of BAX was down regulated at 1.5 mM LC. Blastocyts were vitrified by a modified OPS method and post thaw survivability of blastocysts was higher (P < 0.05) in 1.5 mM LC than other groups. In post thaw blastocysts, mRNA expression of GLUT1, OCT4 and IFN-tau was higher (P < 0.05) in 1.5 mM than other groups. Thus, it can be concluded that supplementation of l-carnitine (1.5 mM) in embryo culture media improved the quality of buffalo embryo production and post thaw blastocysts survivability by reducing fatty acid synthesis, enhancing fatty acid metabolism, and reducing lipid droplet formation.

Abstract
Articular cartilage injury poses a major challenge for both the patient and orthopaedician. Articular cartilage defects once formed do not regenerate spontaneously, rather replaced by fibrocartilage which is weaker in mechanical competence than the normal hyaline cartilage. Mesenchymal stem cells (MSCs) along with different growth factors and scaffolds are currently incorporated in tissue engineering to overcome the deficiencies associated with currently available surgical methods and to facilitate cartilage healing. MSCs, being readily available with a potential to differentiate into chondrocytes which are enhanced by the application of different growth factors, are considered for effective repair of articular cartilage after injury. However, therapeutic application of MSCs and growth factors for cartilage repair remains in its infancy, with no comparative clinical study to that of the other surgical techniques. The present review covers the role of MSCs, growth factors and scaffolds for the repair of articular cartilage injury.

Abstract
The current study was designed to study the persistence and distribution of caprine bone marrow derived mesenchymal stem cells (cBM-MSCs) when administered intra-dermally in experimentally induced cutaneous wounds in rabbits. MSC's from goat bone marrow were isolated and their differentiation potential towards adipogenic and osteogenic lineages were assayed in vitro. The isolated cells were phenotypically analysed using flow cytometry for the expression of MSC specific matrix receptors (CD73, CD105 and Stro-1) and absence of hematopoietic lineage markers. Further, these in vitro expanded MSCs were stained with PKH26 lipophilic cell membrane red fluorescent dye and prepared for transplantation into cutaneous wounds created on rabbits. Five, 2 cm linear full thickness skin incisions were created on either side of dorsal midline of New Zealand white rabbits (n = 4). Four wounds in each animal were implanted intra-dermally with PKH26 labelled cBM-MSCs suspended in 500 µl of Phosphate Buffer Saline (PBS). Fifth wound was injected with PBS alone and treated as negative control. The skin samples were collected from respective wounds on 3, 7, 10 and 14 days after the wound creation, and cryosections of 6 µM were made from it. Fluorescent microscopy of these cryosections showed that the PKH26 labelled transplanted cells and their daughter cells demonstrated a diffuse pattern of distribution initially and were later concentrated towards the wound edges and finally appeared to be engrafted with the newly developed skin tissues. The labelled cells were found retained in the wound bed throughout the period of 14 days of experimental study with a gradual decline in their intensity of red fluorescence probably due to the dye dilution as a result of multiple cell division. The retention of transplanted MSCs within the wound bed even after the complete wound healing suggests that in addition to their paracrine actions as already been reported, they may have direct involvement in various stages of intricate wound healing process which needs to be explored further.

Abstract
The present study examined the comparative expression and secretory profile of vital signaling molecules in buffalo fetal fibroblasts (BFF) and Wharton's jelly (BWJ) feeder layers at different passages. Both feeder layers were expanded up to 8th passage. Signaling molecules viz. bone morphogenetic protein 4 (BMP4), fibroblast growth factor 2 (FGF2), leukemia inhibitory factor (LIF) and transforming growth factor beta 1 (TGFB1) and pluripotency-associated transcriptional factors (POU5F1, SOX2, NANOG, KLF4, MYC and FOXD3) were immunolocalized in the both feeder types. A clear variation in the expression pattern of key signaling molecules with passaging was registered in both feeders compared to primary culture (0 passage). The conditioned media (CM) was collected from different passages (2, 4, 6, 8) of both the feeder layers and was quantified using enzyme-linked immunosorbent assay (ELISA). Concomitant to expression profile, protein quantification also revealed differences in the concentration of signaling molecules at different time points. Conjointly, expression and secretory profile revealed that 2nd passage of BFF and 6th passage of BWJ exhibit optimal levels of key signaling molecules thus may be selected as best passages for embryonic stem cells (ESCs) propagation. Further, the effect of mitomycin-C (MMC) treatment on the expression profile of signaling molecules in the selected passages of BFF and BWJ revealed that MMC modulates the expression profile of these molecules. In conclusion, the results indicate that feeder layers vary in expression and secretory pattern of vital signaling molecules with passaging. Based on these findings, the appropriate feeder passages may be selected for the quality propagation of buffalo ESCs.

Abstract
The present study investigated the combined effect of fibroblast growth factor 2 (FGF2) and vascular endothelial growth factor A (VEGF-A) on estradiol (E2) secretion and relative abundance of mRNA for aromatase enzyme (CYP19A1), proliferating cell nuclear antigen (PCNA) and BCL-2 associated X protein (BAX) in cultured buffalo granulosa cells (GCs). Follicles were isolated and classified into four groups based on size and E2 concentration in follicular fluid (FF): Small, 4-6mm diameter, E2<0.5ng/ml; Medium, 7-9mm, E2=0.5-5ng/ml; Large, 10-13mm, E2=5-40ng/ml; Preovulatory (PFs), >14mm, E2>180ng/ml. The GCs of PF were cultured in 24 well cell culture plates and allowed to become 75-80% confluent. Then cultured GCs were treated with FGF2 (200ng/ml) and VEGF-A (100ng/ml) separately and in combination for three incubation periods (24, 48 and 72h). Estradiol secretion was greater in GCs treated with FGF2+VEGF-A compared to FGF2 or VEGF-A at all incubation periods and was greatest (P<0.05) at 72h of incubation. The relative abundance of CYP19A1 and PCNA mRNA were relatively consistent with the amount E2 secretion. In contrast, the relative abundance of Bax mRNA was less in GCs treated with the combination of FGF2 and VEGF-A as compared to either FGF2 or VEGF-A alone and the least concentration (P<0.05) was at 72h of incubation. Findings with use of immunocytochemistry of cells treated with these factors were consistent to the relative abundance of mRNA transcript for the factor. The present findings indicate that FGF2 and VEGF-A may function in a synergistic manner to promote steroidogenesis and survival of cultured buffalo GCs.

Abstract
The role of growth factors in the modulation of ovarian function is an interesting area of research in reproductive biology. Recently, we have shown the expression and role of IGF, EGF, VEGF and FGF in the follicle and CL. Here, we report the presence of Bone Morphogenetic Proteins (BMPs) and their functional receptors in the corpus luteum (CL) of buffalo. The bubaline CL was classified into four stages according to the morphology and progesterone (P4) concentration. The qPCR, immunoblot and immunohistochemistry studies revealed that BMP2 and BMP Receptors (BMPR1A, BMPR1B and BMPR2) were significantly upregulated during the mid stage whereas BMP4 and BMP7 were upregulated during the early stage of CL (P<0.05). Studies on primary luteal cell culture (LCC) using mid CL showed a significant time and concentration dependent effect of BMP4 and BMP7 (P<0.05). At 100ngml-1, the BMPs maximally stimulated the transcripts of StAR, CYP11A1 and 3βHSD that paralleled with P4 accretion in the media (P<0.05). Further, the BMP4 as well as BMP7 upregulated the transcripts of PCNA and downregulated CASPASE3 in the LCC at the same concentration (P<0.05). Though the combined effect of BMP4 and 7 was significantly higher (P<0.05) than that of individual one, it was not additive. In conclusion, the expression of BMPs and their receptors were dependent on the stages of CL in the buffalo. Treatment of LCC with BMPs in vitro confirmed the presence of functional receptors that stimulated the P4 production and luteal cell survival. Moreover, the results support the concept that the upregulation of P4 and its biosynthetic pathway enzymes such as CYP11A1, StAR and 3βHSD in the CL is likely due to the autocrine and /or paracrine effects of BMP4 and BMP7 under physiological milieu.

Abstract
The present study was designed to investigate the effect of MSCs-conditioned media (CM) on quality buffalo embryo production in vitro. MSCs were harvested from Wharton's jelly of 2-3 month old fetus and MSCs CM was collected. Immunocytochemistry and western blot assay revealed that MSCs secrete several important growth factors viz. FGF-2, IGF-1, LIF, TGF-β, and VEGF. Slaughterhouse derived culture grade cumulus oocyte complexes (COCs) were matured and fertilized in vitro. Presumptive zygotes were divided in four groups and cultured in vitro in respective media viz. group I (100% mSOF), Group II (100% Knockout Media DMEM+SR), Group III (50% CM + 50% mSOF), and group IV (100% CM). It was found that though the cleavage rate did not changed significantly (p < 0.05), but blastocyst rate was increased significantly (p < 0.05) in Group III and IV (24.24 ± 1.34 and 23.29 ± 1.25, respectively) compared to group I and II (16.04 ± 1.46 and 17.72 ± 0.94, respectively). Similarly, TCN was significantly (p < 0.05) higher in 50% CM and 100% CM replacement group (93.33 ± 1.91 and 92.13 ± 1.04, respectively) than the other two groups. It can be concluded from the study that MSCs secrete several important growth factors and MSCs-CM can be effectively used for enhancement of quality buffalo embryo production in vitro.

Abstract
The present study was conducted with an objective of isolation, in vitro expansion, growth kinetics, molecular characterization and in vitro differentiation of fetal adnexa derived caprine mesenchymal stem cells. Mid-gestation gravid caprine uteri (2–3 months) were collected from abattoir to derive mesenchymal stem cells (MSCs) from fetal adnexa {amniotic fluid (cAF), amniotic sac (cAS), Wharton’s jelly (cWJ) and cord blood (cCB)} and expanded in vitro. These cultured MSCs were used at the 3rd passage (P3) to study growth kinetics, localization as well as molecular expression of specific surface antigens, pluripotency markers and mesenchymal tri-lineage differentiation. In comparison to cAF and cAS MSCs, cWJ and cCB MSCs showed significantly (P<0.05) higher clonogenic potency, faster growth rate and low population doubling (PDT) time. All the four types of MSCs were positive for alkaline phosphatase (AP) and differentiated into chondrogenic, osteogenic, and adipogenic lineages. These stem cells expressed MSC surface antigens (CD73, CD90 and CD105) and pluripotency markers (Oct4, Sox2, Nanog, KLF, cMyc, FoxD3) but did not express CD34, a hematopoietic stem cell marker (HSC) as confirmed by RT-PCR, immunocytochemistry and flow cytometric analysis. The relative mRNA expression of MSC surface antigens (CD73, CD90 and CD105) was significantly (P<0.05) higher in cWJ MSCs compared to the other cell lines. The mRNA expression of Oct4 was significantly (P<0.05) higher in cWJ, whereas mRNA expression of KLF and cMyc was significantly (P<0.05) higher in cWJ and cAF than that of cAS and cCB. The comparative assessment revealed that cWJ MSCs outperformed MSCs from other sources of fetal adnexa in terms of growth kinetics, relative mRNA expression of surface antigens, pluripotency markers and tri-lineage differentiation potential, hence, these MSCs could be used as a preferred source for regenerative medicine.

Abstract
The aim of the present study was to demonstrate the modulatory role of leptin on bubaline granulosa cells (GCs) and luteal cells (LCs) functions using an in vitro cell culture system and to establish a cross talk between leptin and insulin-like growth factor-1 (IGF-1). GCs were collected from group IV follicles (>13 mm size) and LCs from mid-luteal phase corpus luteum and were grown in serum-containing media supplemented with leptin at three different dose rates (0.1, 1, and 10 ng/mL) and time durations (24, 48, and 72 hours). We evaluated the production and secretion of estradiol (E2) and progesterone (P4) using RIA and the mRNA expression of steroidogenic acute regulatory protein (STARD1), cytochrome P450 cholesterol side-chain cleavage (CYP11A1), 3β-hydroxysteroid dehydrogenase (3β-HSD), cytochrome P450 aromatase (CYP19A1), sterol regulatory element-binding protein 1 (SREBP1), steroidogenic factor-1 (SF1), anti-apoptotic gene PCNA, pro-apoptotic gene caspase 3 and endothelial cell marker, Von Willebrand factor (vWF), using quantitative real-time polymerase chain reaction. The results depicted a direct inhibitory action of leptin on GCs steroidogenesis in a time-dependent manner (P < 0.05), whereas in the presence of IGF-1 the inhibitory effect was reverted. Furthermore, leptin augmented both cellular proliferation (PCNA) and apoptosis (caspase 3). On the other hand, in LCs, leptin alone showed an apparent stimulatory effect on steroidogenesis (P < 0.05); however, in the presence of IGF-1, an antagonistic effect was witnessed. Moreover, leptin had an inhibitory effect on apoptosis while promoted cellular proliferation and angiogenesis. These findings were further strengthened by immunocytochemistry. To conclude, these observations for the first time reported that in buffaloes leptin has a direct dose-, time-, and tissue-dependent effect on ovarian steroidogenesis, angiogenesis, and cytoprotection, and furthermore, it can regulate the effect of systemic factors like IGF-1. Hence, this in vitro study provides an insight into the putative roles of leptin alone and its interactions in vivo.

Abstract
The objective of this study was to characterize in vitro expression and secretion of vascular endothelial growth factor (VEGF) in bubaline granulosa cells (GC), grown in serum containing media supplemented with luteinizing hormone (LH), insulin like growth factor-1 (IGF-1), and epidermal growth factor (EGF) at three different doses and time durations. GCs were collected from ovarian follicles of varying diameters [Gp-I (small), 4-6 mm; Gp-II (medium), 7-9 mm; Gp-III (large), 10-13 mm; Gp-IV (pre-ovulatory), >13 mm]. In general, each of the three treatments resulted in a dose as well as time dependent increase in the mRNA expression and secretion of VEGF in the cultured GCs of Gp-IV follicles. These results were well supported by our observations on immunocytochemistry in Gp IV granulosa cell culture (GCC). We also looked into the expression dynamics of an anti-apoptotic factor--proliferating cellular antigen (PCNA) and a pro-apoptotic factor--Bcl-2-associated X protein (BAX) in GCs of Gp IV follicles on treatments with LH, IGF-1, and EGF to evaluate their cytoprotective/anti-apoptotic property. Relative expressions of PCNA and BAX showed a mutually opposite trend with the PCNA expression increasing and BAX expression decreasing with increase in dose and time to reach the zenith (P<0.05) and nadir (P<0.05) at the highest dose(s) at the maximum time duration (72 h) for PCNA and BAX respectively on treatment with all the three factors. Thus, it can be concluded that LH, IGF-1, and EGF treatments have a cytoprotective/anti-apoptotic effect and stimulate VEGF production in granulosa cells of bubaline pre-ovulatory follicles.

Abstract
BACKGROUND AND OBJECTIVES Use of somatic cells as a feeder layer to maintain the embryonic stem cells (ESCs) in undifferentiated state limits the stem cell research design, since experimental data may result from a combined ESCs and feeder cell response to various stimuli. Therefore, present study was designed to evaluate the developmental competence of the buffalo ESCs over different homogenous feeders and compare with various extracellular matrices using different concentrations of LIF. METHODS AND RESULTS Inner cell masses (ICMs) of in vitro hatched blastocysts were cultured onto homologous feeders viz. fetal fibroblast, granulosa and oviductal cell feeder layers and synthetic matrices viz. fibronectin, collagen type I and matrigel in culture medium. Developmental efficiency was found higher for ESCs cultured on fetal fibroblast and granulosa layers (83.33%) followed by fibronectin (77.78%) at 30 ng LIF. Oviductal feeder was found to be the least efficient feeder showing only 11.11% undifferentiated primary ESC colonies at 30 ng LIF. However, neither feeder layer nor synthetic matrix could support the development of primary colonies at 10 ng LIF. Expression of SSEA- 4, TRA-1-60 and Oct-4 were found positive in ESC colonies from all the feeders and synthetic matrices with 20 ng and 30 ng LIF. CONCLUSIONS Fetal fibroblast and granulosa cell while, amongst synthetic matrices, fibronectin were found to be equally efficient to support the growth and maintenance of ESCs pluripotency with 30 ng LIF. This well-defined culture conditions may provide an animal model for culturing human embryonic stem cells in the xeno-free or feeder-free conditions for future clinical applications.

Abstract
Autogenic and allogenic bone marrow derived mesenchymal stem cells (BM-MSCs) were compared for repair of bone gap defect in rabbits. BM-MSCs were isolated from bone marrow aspirates and cultured in vitro for allogenic and autogenic transplantation. A 5mm segmental defect was created in mid-diaphysis of the radius bone. The defect was filled with hydroxyapatite alone, hydroxyapatite with autogeneic BM-MSCs and hydroxyapatite with allogenic BM-MSCs in groups A, B and C, respectively. On an average 3.45×10(6) cells were implanted at each defect site. Complete bridging of bone gap with newly formed bone was faster in both treatment groups as compared to control group. Histologically, increased osteogenesis, early and better reorganization of cancellous bone and more bone marrow formation were discernible in treatment groups as compared to control group. It was concluded that in vitro culture expanded allogenic and autogenic BM-MSCs induce similar, but faster and better healing as compared to control.

Abstract
The present study was designed to investigate whether gonadotropins [follicle-stimulating hormone (FSH) and luteinizing hormone (LH)] and buffalo follicular fluid (bFF) supplementation in maturation medium influences the transcript abundance of germ cell marker genes [maternal antigen that embryos require (MATER), Zygote arrest 1 (ZAR1), growth differentiation factor 9 (GDF9), and bone morphogenetic protein 15 (BMP15)] mRNA in buffalo (Bubalus bubalis) oocytes. Buffalo ovaries were collected from local abattoir, oocytes were aspirated from antral follicles (5-8 mm) and matured in vitro using two different maturation regimens, viz, group A: gonadotropin (FSH and LH) and group B: non-gonadotropin-supplemented maturation medium containing 20% buffalo follicular fluid (bFF). mRNA was isolated from immature (330) and in vitro matured oocytes from both the groups (A, 320; B, 340), and reverse transcribed using Moloney murine leukemia virus reverse transcriptase. Expression levels of MATER, ZAR1, GDF9, and BMP15 mRNA transcripts were analyzed in oocytes of both maturation groups as well as immature oocytes using real-time PCR. QPCR results showed that GDF9 and BMP15 transcripts were significantly (p<0.05) influenced with gonadotropins and bFF supplementation during in vitro maturation of buffalo oocyte; however, MATER and ZAR1 transcripts were not influenced with gonadotropins and bFF supplementation in vitro. These results indicated that the expression levels of MATER, ZAR1, GDF9, and BMP15 mRNA were varied differentially during in vitro maturation of buffalo oocyte and were found to be gonadotropins (FSH and LH) or bFF dependent for GDF9 and BMP15.

Abstract
Leptin is supposed to play a crucial role in ovarian luteal dynamics. The present study was aimed to investigate the importance of leptin and its receptors in buffalo corpus luteum (CL) obtained from different stages of the estrous cycle. Real-time RT-PCR (qPCR), western blot and immunohistochemistry techniques were applied to investigate mRNA expression, protein expression and localization of examined factors. Additionally to assess the contribution of leptin in progesterone production the expression profiles of StAR, P450scc and HSD were also investigated. In general, we demonstrated presence of leptin and its receptors in buffalo CL during the estrous cycle. The mRNA levels of leptin and its receptors were significantly up regulated in (P<0.05) in all the stages and highest levels were observed in mid and late luteal stages consistent with in vivo luteinization of buffalo CL and declined coincidental to luteal regression. The expression of StAR, P450scc and HSD factors maintained low in early luteal phase, after that level of expression increased steadily to show a significant rise (P<0.05) in mid luteal phase followed by gradual decline in late luteal phase and regressed CL and this correlates well with the Ob and ObR receptor activity, verifying their key role in progesterone and other steroids production in functional CL. As revealed by immunohistochemistry, leptin protein was localized predominantly in large luteal cells however leptin receptor (Ob-R) was localized in large luteal cells as well as in endothelial cells. It can be concluded from our study that leptin via its autocrine/paracrine effects play a significant role in promoting angiogenesis, steroidogenesis and also acts as key survival factor in bubaline CL.

Abstract
Immune privileged mesenchymal stem cells (MSCs) can differentiate into multiple cell types and possess great potential for human and veterinary regenerative therapies. This study was designed with an objective to isolate, expand and characterize buffalo bone marrow-derived MSCs (BM-MSCs) at molecular and cellular level. Buffalo BM-MSCs were isolated by Ficoll density gradient method and cultured in Dulbecco's modified Eagle's medium supplemented with fetal bovine serum (FBS). These cells were characterized through alkaline phosphatase (AP) staining, colony-forming unit (CFU) assay, mRNA expression analysis (CD 73, CD 90, CD 105, Oct4 and Nanog), immunolocalization along with flow cytometry (Stro 1, CD 73, CD 105, Oct4, Sox2 and Nanog) and in situ hybridization (Oct4 and Sox2). Multilineage differentiation (osteogenic, adipogenic and chondrogenic) was induced in vitro, which was further assessed by specific staining. Buffalo BM-MSCs have the capacity to form plastic adherent clusters of fibroblast-like cells and were successfully maintained up to 16(th) passage. These cells were AP positive, and further CFU assay confirmed their clonogenic property. RT-PCR analysis and protein localization study showed that buffalo BM-MSCs are positive for various cell surface markers and pluripotency markers. Cytoplasmic distribution of mRNA for pluripotency markers in buffalo BM-MSCs and multilineage differentiation were induced in vitro, which was further assessed by specific staining. To the best of our knowledge, this is the first report of buffalo BM-MSCs, which suggests that MSCs can be derived and expanded from buffalo bone marrow and can be used after characterization as a novel agent for regenerative therapy.

Cells are blessed with a group of stress protector molecules known as heat shock proteins (HSPs), amongst them HSP70, encoded by HSPA-1A gene, is most abundant and highly conserved protein. Variety of stresses hampers the developmental competence of embryos under in vivo and in vitro conditions. Present work was designed to study the quantitative expression of HSPA-1A mRNA in immature oocytes (IMO), matured oocytes (MO), in vitro produced (IVP) and in vivo-derived (IVD) buffalo embryos to assess the level of stress to which embryos are exposed under in vivo and in vitro culture conditions. Further, HSPA-1A gene sequence was analysed to determine its homology with other mammalian sequences. The mRNA expression analysis was carried out on 72 oocytes (40 IMO; 32 MO), 76 IVP and 55 IVD buffalo embryos. Expression of HSPA-1A was found in oocytes and throughout the developmental stages of embryos examined irrespective of the embryo source; however, higher (p < 0.05) expression was observed in 8-16 cell, morula and blastocyst stages of IVP embryos as compared to IVD embryos. Phylogenetic analysis of bubaline HSPA-1A revealed that it shares 91-98% identity with other mammalian sequences. It can be concluded that higher level of HSPA-1A mRNA in IVP embryos in comparison with in vivo-derived embryos is an indicator of cellular stress in IVP system. This study suggests need for further optimization of in vitro culture system in which HSPA-1A gene could be used as a stress biomarker during pre-implantation development.

Abstract
Effect of sodium nitroprusside (SNP), a nitric oxide (NO) donor, on in vitro survival, growth, steroidogenesis, and apoptosis of buffalo preantral follicles (PFs) was investigated. PFs (200~250 µm) were isolated by micro-dissection and cultured in 0 (control), 10-3, 10-5, 10-7, and 10-9 M SNP. To examine the reversible effect of SNP, PFs were cultured with 10-5 M SNP + 1 mM Nω-nitro-L-arginine methyl ester (L-NAME) or 1.0 µg hemoglobin (Hb). The results showed that greater concentrations of SNP (10-3, 10-5, 10-7 M) inhibited (p < 0.05) FSH-induced survival, growth, antrum formation, estradiol production, and oocyte apoptosis in a dose-dependent manner. However, a lower dose of SNP (10-9 M) significantly stimulated (p < 0.05) the survival, growth, antrum formation, follicular oocyte maturation, and stimulated progesterone secretion compared to the control. A combination of SNP + L-NAME promoted the inhibitor effect of SNP while a SNP + Hb combination reversed this effect. Nitrate and nitrite concentrations in the culture medium increased (p < 0.05) in a dose-dependent manner according to SNP concentration in the culture medium. At higher concentrations, SNP had a cytotoxic effect leading to follicular oocyte apoptosis whereas lower concentrations have stimulatory effects. In conclusion, NO exerts a dual effect on its development of buffalo PFs depending on the concentration in the culture medium.

Abstract
The present study was designed to investigate the expression of nitric oxide synthase (NOS) isoforms in buffalo ovarian preantral (PFs), antral (AFs) and ovulatory (OFs) follicles (Experiment 1); effect of NO on in vitro survival and growth of PFs (Experiment 2) and NOS activity in immature oocytes by NADPH-diaphorase test (Experiment 3). In Experiment 1, NOS isoforms (neuronal, inducible and endothelial) were localized immunohistochemically; mRNA and protein expression was analyzed by semi-quantitative RT-PCR and western blot, respectively. In Experiment 2, PFs were isolated by micro-dissection method from buffalo ovaries and cultured in 0 (control), 10(-3), 10(-5), 10(-7) and 10(-9) M sodium nitroprusside (SNP). PFs were further cultured with 10(-5) M SNP + 1.0 mM N(ω)-nitro-L-arginine methyl ester (L-NAME) or 1.0 μg/ml hemoglobin (Hb) to examine the reversible effect of SNP. Immunohistochemical studies demonstrated that inducible nitric oxide synthase (iNOS) immunoreactivity was predominantly localized in granulosa and theca cells whereas, neuronal (nNOS) and endothelial (eNOS) nitric oxide synthase in the theca, granulosa and cumulus cells of PFs, AFs and OFs. The amount of mRNA as well as protein of nNOS and eNOS was found similar between different stages of follicles. In contrast, higher level of iNOS mRNA was observed in OFs and protein in the AFs. Higher doses of SNP (10(-3), 10(-5), 10(-7) M) inhibited (P < 0.05) while, lower dose of SNP (10(-9) M) stimulated (P < 0.05) the survival, growth, and antrum formation of PFs. The inhibitory effects of SNP were reversed by Hb, while L-NAME was not found effective. In conclusion, expression of NOS isoforms mRNA and protein in PFs, AFs, and OFs and NOS enzyme activity in immature follicular oocytes suggest a role for NO during ovarian folliculogenesis in buffalo. NO plays a dual role on growth and survival of PFs depending on its concentration in the culture medium.

Abstract
OBJECTIVE Investigate the effect of various growth factors viz. IGF-I, TGF-alpha + TGF-beta1 and bFGF either alone or in combination, with FSH on in vitro growth, survival, antrum formation, steroidogenesis and apoptosis of buffalo preantral follicles (PFs). METHODS Buffalo ovaries were collected from abattoir; PFs were isolated and divided into five treatment groups. TCM-199 supplemented with 10% FBS, 1% ITS+EGF+FSH control (group a), control+IGF-I (group b), control + TGF-alpha + TGF-beta1 (group c), control + IGF-I + TGF-alpha + TGF-beta1 (group d) and control+bFGF (group e). Progesterone (P4) and 17beta-estradiol (E2) concentrations were evaluated by RIA and apoptosis by TUNEL assay. RESULTS TGF-alpha + TGF-beta1 inhibited follicular survival and induced oocyte apoptosis, while IGF-I + TGF-alpha + TGF-beta1 suppressed this inhibitory action. IGF-I significantly (P < 0.05) enhanced the follicle survival, growth and induced antrum formation. FGF had greater effects on both survival and growth rate of oocytes than other treatment groups. Progesterone and estradiol accumulation was significantly (P < 0.05) greater in presence of FGF and IGF-I than TGF-alpha + TGF-beta1. CONCLUSION Survival, growth, antrum formation and steroidogenesis are stimulated by IGF-I and bFGF, whereas TGF-alpha + TGF-beta1 inhibited growth and survival of PFs which led to induced oocyte apoptosis in buffalo PFs.
