Abstract
The tolerance of Chenopodium ambrosioides to some heavy metals under in vitro environment was thoroughly investigated. A micropropagation protocol was developed to facilitate the mass production of plants and to identify metals-tolerant species for potential use in the restoration of polluted areas. Nodal explants exhibited callus formation when treated with N6-benzyladenin (BA) (1.5 mg/l) and a combination of BA/α-naphthalene acetic acid (NAA) at concentrations of 1.5/1.0 mg/l on the Murashige and Skoog (MS) medium. The optimal shoot formation was achieved with the callus grown on a medium enriched with 1.5/1.0 mg/l BA/NAA, resulting in an impressive number (21.89) and length (11.79 cm) of shoots. The in vitro shoots were rooted using NAA (1.0 and 1.5 mg/l) and were acclimatized in pots with 71% survival rate. After standardizing micropropagation protocol, the in vitro shoots were subjected to various doses of lead nitrate (Pb(NO3)2 and cadmium chloride (CdCl2). Pb(NO3)2 and CdCl2 in the media let to a reduction in shoot multiplication, decreasing from 18.73 in the control group to 11.31 for Pb(NO3)2 and 13.89 for CdCl2 containing medium. However, Pb(NO3)2 and CdCl2 promoted shoot length from 5.61 in the control to 9.86 on Pb(NO3)2 and 12.51 on CdCl2 containing medium. In the case of Pb(NO3)2 treated shoots, the growth tolerance index (GTI) ranged from117.64% to 194.11%, whereas for CdCl2 treated shoots, the GTI ranged from 188.23% to 264.70%. Shoots treated with high level of Pb(NO3)2induced reddish-purple shoots, while a low level of Pb(NO3)2 induced shoots displayed both green and reddish-purple colors in the same explants. In CdCl2 treated culture, the toxic effects were narrow leaf lamina, elongated petiole and a dark reddish purple coloration. These findings highlight the remarkable potential of C. ambrosioides to maintain growth and organogenesis even in the presence Pb(NO3)2 and CdCl2 on the MS medium, indicating a high degree of metal tolerance.

Abstract
The two gonadotropins, FSH and LH, stimulate growth and development of the gonads through gonadal biosynthesis of steroid hormones and growth factors. To date, cDNA sequences encoding gonadotropin subunits have been isolated and characterized from a large number of fish species. Recently, we successfully cloned and characterized gonadotropins (LHβ, FSHβ, and GPα) from the pituitary glands of the catfish, Heteropneustes fossilis. In the present study, we describe herein the production of recombinant stinging catfish, H. fossilis (hf) FSH (rhfFSH) and LH (rhfLH) using the methylotrophic yeast P. pastoris expression system. We further explored the hypothesis that the recombinant gonadotropins can modulate the hypothalamus-pituitary-ovarian (HPO) axis genes (avt, it, gnrh2, kiss2, and cyp19a1a) and regulate their transcriptional profile and steroid levels in relation to their annual developmental stage during preparatory and pre-spawning phases under in-vitro conditions. We found that the different concentrations of recombinant rhfFSH and rhfLH significantly stimulated E2 levels in the preparatory and prespawning season, and also upregulated gonadal aromatase gene expression in a dose dependent manner. Our results demonstrate that the yeast expression system produced biologically active recombinant catfish gonadotropins, enabling the study of their function in the catfish.

Abstract
RESEARCH QUESTION Does the addition of an antioxidant agent, xanthoangelol (XAG), to the culture medium improve in-vitro development of porcine embryos? DESIGN Early porcine embryos were incubated in the presence of 0.5 μmol/l XAG in in-vitro culture (IVC) media and analysed using various techniques, including immunofluorescence staining, reactive oxygen species (ROS) detection, TdT-mediated dUTP nick-end labelling (TUNEL), and reverse transcription followed by quantitative polymerase chain reaction (RT-qPCR). RESULTS The addition of 0.5 μmol/l XAG to IVC media increased the rate of blastocyst formation, total cell number, glutathione concentrations and proliferative capacity, while reducing reactive oxygen species concentrations, apoptosis and autophagy. In addition, upon XAG treatment, the abundance of mitochondria and mitochondrial membrane potential significantly increased (both P < 0.001), and the genes related to mitochondrial biogenesis (TFAM, NRF1 and NRF2) were significantly up-regulated (all P < 0.001). XAG treatment also significantly increased the endoplasmic reticulum abundance (P < 0.001) and reduced the concentrations of endoplasmic reticulum stress (ERS) marker GRP78 (P = 0.003) and expression of the ERS-related genes EIF2α, GRP78, CHOP, ATF6, ATF4, uXBP1 and sXBP 1 (all P < 0.001). CONCLUSION XAG promotes early embryonic development in porcine embryos in vitro by reducing oxidative stress, enhancing mitochondrial function and relieving ERS.

Abstract
BACKGROUND Chlorogenic acid (CGA) is one of the well-known polyphenol compounds possessing several important biological and therapeutic functions. In order to optimize a culture system to achieve complete development of follicles, we focused on the effects of CGA supplementation during in vitro culture (IVC) on follicular development, oxidative stress, antioxidant capacity, developmental gene expression, and functional potential in cultured mouse ovarian tissue. METHODS AND RESULTS The collected whole murine ovaries were randomly divided into four groups: (1) non-cultured group (control 1) with 7-day-old mouse ovaries, (2) non-cultured group (control 2) with 14-day-old mouse ovaries, (3) cultured group (experimental 1) with the culture plates containing only the basic culture medium, (4) cultured group (experimental 2) with the culture plates containing basic culture medium + CGA (50, 100 and 200 µmol/L CGA). Afterward, histological evaluation, biochemical analyses, the expression assessment of genes related to follicular development and apoptosis as well as the analysis of 17-β-estradiol were performed. The results showed that supplementation of ovarian tissue with the basic culture media using CGA (100 µmol/l) significantly increased the survival, developmental and functional potential of follicles in whole mouse ovarian tissues after 7 days of culture. Furthermore, CGA (100 µmol/L) attenuated oxidative damage and enhanced the concentration of antioxidant capacity along with developmental gene expression. CONCLUSION It seems that supplementation of ovarian tissue with culture media using CGA could optimize follicular growth and development in the culture system.

Abstract
The thin cell layer (TCL) culture system was initially reported in relation to the model plant Nicotiana tabacum, giving rise to 47 years of continuous application and investigation on micropropagation and plant breeding of over 100 plant species or hybrids. The small sizes of the tissue sections (100 μm to 1-2 mm in thickness), its classification into transverse TCL (tTCL) or longitudinal TCL (lTCL) categories, and the interaction between the cultured cells and the culture medium are the main drivers of its efficacy in tens of plants for the induction of somatic embryogenesis, relative to the conventional in-vitro culture system. Furthermore, it promotes higher productivity and reduced time in the proliferation of cultures, which is key for the differentiation of cells and plant tissues. This chapter describes the main characteristics of the TCL sections, and the interaction between cells under in-vitro culture. In addition, it highlights the latest findings reporting the success of TCL in ornamental, herbaceous, woody, and recalcitrant plants. In most cases, studies on the use of TCL in combination with techniques such as bioreactors, histology, genetic transformation, and fidelity analysis, provide indisputable evidence that highlights the importance of this technique in plant biotechnology. Finally, the perspectives on TCL use are described, underlining the advantages and constraints of the technique for its continued use and future application.

Abstract
OBJECTIVE To preserve human ovarian tissue structure and improve follicular growth and survival during in-situ culture, various biomaterials are used. In this study we aimed to compare agar as a cultivation substrate with matrigel-coated insert in order to achieve an optimum system for in-situ human follicle culture. STUDY DESIGN Frozen-thawed human ovarian cortical tissues were cultured on either matrigel-coated inserts or agar-soaked substrates. The proportion of morphologically viable and degenerated follicles at different developmental stages, secreted hormonal levels, and apoptotic and proliferation gene expressions were compared between the cultured groups after 7-days of culture. RESULTS The follicular growth was not significantly different between the two cultured groups, although showing higher percentage of growing follicles in agar cultured group. The secreted hormonal levels didn't have any difference between two cultured groups. Although the apoptotic gene expressions didn't show any difference between the cultured groups, the apoptotic index was lower in agar cultured group. In addition, Ki67 gene expression, a proliferative marker, showed a significantly higher expression in agar cultured group. CONCLUSION Based on the results, agar is as suitable as matrigel-coated inserts for the survival and growth of follicles during culture. Therefore, agar can be an inexpensive alternative substrate for culturing frozen-thawed human ovarian cortical strips.

Abstract
Different factors, such as basic fibroblast growth factor (bFGF) and kit ligand (KL), are used in ovarian cortical culture to promote activation of primordial follicles. In the present study, the effects of bFGF and KL, alone and in combination, were evaluated on human follicular activation and growth during in-situ cortical culture. Slow frozen-thawed human ovarian cortical tissues (n = 6) were cultured in 4 different groups: 1) control (base medium), 2) KL (base medium; BM + 100 ng/ml KL), 3) bFGF (BM + 100 ng/ml bFGF) and 4) bFGF + KL (BM + 100 ng/ml KL + 100 ng/ml bFGF) for a week. The proportion of morphologically normal and degenerated follicles at different developmental stages, secreted hormonal levels and specific gene expressions were compared. Although the proportion of growing follicles was higher than primordial counterpart in all cultured groups, no significant differences were observed among the cultured groups. In all cultured groups, anti-Müllerian hormone (AMH), progesterone and estradiol hormones levels increased after 7 days of culture; however, this increase was only significant for estradiol in the bFGF + KL group. The expression of Ki67 gene indicated an increase in ovarian cell proliferation in the three experimental groups compared to the control group, however this increment was only significant for the bFGF + KL group. It can be concluded that KL and bFGF factors individually have no beneficial effects on in-situ follicular growth, but their combination positively influences steroidogenesis of granulosa cells without significantly increasing the number of growing follicles.

Abstract
RESEARCH QUESTION Does a three-dimensional culture system based on magnetic levitation with nanoparticles assembly maintain the follicular structure and viability with adequate growth rates leading to oocyte maturation after long-term culture? DESIGN Randomized-controlled trial of treatments in a bovine model. Secondary follicles (n = 213) isolated from bovine ovaries were cultured in a two-dimensional system (two-dimensional control) or three-dimensional levitation system with different concentrations (three-dimensional 50 µl/ml, 100 µl/ml and 200 µl/ml) of magnetic nanoparticles. Follicular growth (diameter, daily growth and growth patterns), morphology (normal, degenerated and extruded follicles), antrum formation, oocyte viability and chromatin configuration were assessed. RESULTS Secondary follicles of three-dimensional 200-µl/ml treatment showed higher viability, antrum formation and lower degeneration rates than two-dimensional control. Also, follicles cultured in the three-dimensional 200-µl/ml treatment presented a most homogenous daily growth rate as shown by the lowest variance and standard deviation. Compared with the two-dimensional control, the proportion of non-growing and slow-growing follicles were 3.8-fold lower and 1.6-fold higher, respectively, in the three-dimensional 200-µl/ml treatment. After in-vitro maturation, the three-dimensional 200-µl/ml had a greater proportion of viable oocytes (1.7-fold) and meiotic resumption rates (2.4-fold) than the two-dimensional control treatment. CONCLUSION The three-dimensional levitation culture system improves the viability of in-vitro development of bovine secondary follicles, antrum formation and lower extrusion and degeneration rates and adequate growth rate leading to relevant oocyte viability and meiotic resumption after in-vitro maturation. This approach does not require a specific medium, and has the potential as an alternative method to in-vitro follicle culture in several species, including humans.

Abstract
The mammalian testis has two main roles, production of gametes for reproduction and synthesis of steroid- and peptide hormones for masculinization. These processes are tightly regulated and involve complex interactions between a number of germ and somatic cell-types that comprise a unique microenvironment known as the germ stem cell niche. In humans, failure of normal testicular development or function is associated with susceptibility to a variety of male reproductive disorders including disorders of sex development, infertility and testicular cancer. Whilst studies in rodent models have provided detailed insight into the signaling pathways and molecular mechanisms that regulate the testis, there are important species differences in testicular development, function and reproductive disorders that highlight the need for suitable experimental models utilising human testicular tissues or cells. In this review, we outline experimental approaches used to sustain cells and tissue from human testis at different developmental time-points and discuss relevant end-points. These include survival, proliferation and differentiation of cell lineages within the testis as well as autocrine, paracrine and endocrine function. We also highlight the utility of these experimental approaches for modelling the effects of environmental exposures on testicular development and function.

Abstract
Ovarian tissue is increasingly being collected from cancer patients and cryopreserved for fertility preservation. While the only available option to restore fertility is autologous transplantation, this treatment is not appropriate for all patients due to the risk of reintroducing cancer cells and causing disease recurrence. Harnessing the full reproductive potential of this tissue to restore fertility requires the development of culture systems that support oocyte development from the primordial follicle stage. While this has been achieved in the mouse, the goal of obtaining oocytes of sufficient quality to support embryo development has not been reached in higher mammals despite decades of effort. In vivo, primordial follicles gradually exit the resting pool, whereas when primordial follicles are placed into culture, global activation of these follicles occurs. Therefore, the addition of a factor(s) that can regulate primordial follicle activation in vitro may be beneficial to the development of culture systems for ovarian tissue from cancer patients. Several factors have been observed to inhibit follicle activation, including anti-Müllerian hormone, stromal-derived factor 1 and members of the c-Jun-N-terminal kinase pathway. This review summarizes the findings from studies of these factors and discusses their potential integration into ovarian tissue culture strategies for fertility preservation.

Abstract
BACKGROUND This study evaluated the performance of routine permanent stain and cultivation method in comparison with polymerase chain reaction assay as the reference technique to detect Blastocystis sp. METHODS A cross-sectional study was conducted among aboriginal populations that reside in Pahang, Peninsular Malaysia in Feb to Mar 2015. A total of 359 stool samples were examined using Wheatley's trichrome stain, in-vitro cultivation in Jones' medium and PCR assay. Positive amplicons were subjected to sequencing and phylogenetic analysis. RESULTS Fifty-six (15.6%) samples were detected positive with Blastocystis sp. by Wheatley's trichrome stain and 73 (20.3%) by in-vitro culture, while PCR assay detected 71 (19.8%) positive samples. Detection rate of Blastocystis sp. was highest in combination of microscopic techniques (27.9%). The sensitivity and specificity of Wheatley's trichrome staining and in-vitro culture techniques compared to PCR assay were 49.3% (95% CI: 37.2-61.4) and 92.7% (95% CI: 89.1-95.4) and 39.4% (95% CI: 28.0-51.8) and 84.4% (95% CI: 79.7-88.4), respectively. However, the sensitivity [60.6% (95% CI: 48.3-71.9)] of the method increased when both microscopic techniques were performed together. False negative results produced by microscopic techniques were associated with subtype 3. The agreement between Wheatley's trichrome stain, in-vitro culture and combination of microscopic techniques with PCR assay were statistically significant by Kappa statistics (Wheatley's trichrome stain: K = 0.456, P<0.001; in-vitro culture: K = 0.236, P<0.001 and combination techniques: K = 0.353, P<0.001). CONCLUSION The combination of microscopic technique is highly recommended to be used as a screening method for the diagnosis of Blastocystis infection either for clinical or epidemiological study to ensure better and accurate diagnosis.

Abstract
In this study, anterior pituitary glands were collected from 12 young male buffalo calves after slaughter, cultured with gonadotropin releasing hormone (GnRH) and estrogen stimulus and the extract obtained. Adult male rabbits (n = 15) were divided into three equal groups. Rabbits of Group A served as control; those of Groups B and C were given extract containing 4 and 8 mIU of follicle stimulating hormone (FSH), respectively twice daily for 3 weeks. Body weight of rabbits was recorded before and after treatment; blood samples were collected after treatment and analyzed for hemoglobin (Hb), red blood cell (RBC) count, white blood cell (WBC) count, packed cell volume (PCV), platelet counts, mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH), while serum samples were analyzed for FSH and total cholesterol. Then, all rabbits were slaughtered, and weight of paired testes was recorded. Results showed that the values for weight gain, RBC count, WBC count, PCV and MCH did not differ among rabbits of three groups. Blood Hb was greater (P < 0.05) in rabbits of Group B than Group C. Testis weight, serum FSH, total cholesterol and blood platelets count were greater in rabbits of Groups B and C, while MCV was less in rabbits of Group C, compared to the control (P < 0.05). In conclusion, in vitro cultured cells of adenohypophysis from male buffalo calves showed FSH activity. This FSH increased testes size, serum FSH, total cholesterol and blood platelets counts and decreased MCV in rabbits. However, it had no effect on weight gain, RBC counts, WBC counts, PCV and MCH.
