Abstract
Feeder cells are essential to derive pluripotent stem cells (PSCs). Mouse embryonic fibroblasts (MEF) are widely used as feeder to generate and culture embryonic stem cells (ESCs) and induced PSCs (iPSCs) in many species. However it may not be suitable for livestock ESCs/iPSCs due to interspecies difference. Previously we derived bovine iPSCs from bovine Sertoli cells using MEF feeder. Here we compared the effects of MEF feeder and bovine embryonic fibroblasts (BEF) feeder on the maintenance of bovine iPSC pluripotency and morphology as well their contributions to the naïve-like conversion, based on a naïve medium (NM). The results showed successful conversion of the primed bovine iPSCs to naïve-like state within 3-4 days both on MEF feeder and BEF feeder in NM (termed as MNM and BNM respectively). These naïve-like iPSCs showed normal karyotype. There were more iPSC colonies under BNM condition than MNM condition. Epigenetically, histone modification H3K4 was upregulated, while H3K27 was downregulated in the naïve-like iPSCs. We further analyzed the naïve markers and differentiation potential both in vitro and in vivo of these cells, which were all reserved throughout the maintenance. Together, bovine naïve-like iPSCs can be generated both on MEF and BEF feeder in NM condition. The BNM condition is able to sustain the pluripotency and differentiation potential of the naïve-like bovine iPSCs, and improve the conversion efficiency.

Abstract
Schisandrin A and B (Sch A and B) are the important components of Asian dietary supplement and phytomedicine Schisandra chinensis (S. chinensis). They can enhance adult neurogenesis in vivo; however, these effects still need to be verified. Here NE-4 C neural stem cells (NSCs) were employed as the in vitro model and treated with Sch A and B at 0.1 μg/mL. EdU (5-Ethynyl-2'-deoxyuridine) labeling showed that both Sch A and B treatments enhanced NSC proliferation. Real-time PCR analysis showed the mRNA abundances of telomerase gene Tert and cell cycle gene Cyclin D1 were significantly up-regulated after the treatments. During the neurosphere induction, Sch B enhanced the neurosphere formation and neuronal differentiation, and increased the neurosphere semidiameters. Detection of the neuron differentiation marker Mapt indicates that both Sch A and B, especially Sch B, benefits the induced neuronal differentiation. Sch B treatment also enhanced mRNA expressions of the neurosphere-specific adhesion molecule Cdh2 and Wnt pathway-related genes including Mmp9, Cyclin D1 and β-catenin. Together, Sch A especially Sch B, promotes the proliferation, affects the survival, differentiation and neurogenesis of NSCs, which is consistent with their in vivo effects. This study provides further clue on the potential neuropharmacological effects of S. chinensis.

Abstract
Objective: Sertoli cells (SCs) are important sustentacular cells in the seminiferous tubules of the testis. Isolation and identification of SCs are the premise for studying their functions. Since New Zealand rabbit is a stable strain which is widely used for biomedical research and animal farming, this study aimed to develop a simple and effective protocol for SC isolation in New Zealand rabbits. Materials and Methods: The SCs of three 30-day-old New Zealand rabbits were isolated by incubation with enzymatic digestion I (Dulbecco’s modified Eagle medium supplemented with 1 mg/ml collagenase IV and 50 μg/ml DNase I) and digestion II (digestion I + 1 mg/ml hyaluronidase + 1 mg/ml trypsin), as well as differential plating. The cells were enriched and identified by using immunocytochemical staining and reverse transcription polymerase chain reaction analysis. Results: Homogeneous cells were obtained. They presented the typical large cell body and an irregular pyramidal shape after differential plating and passaging. These cells expressed mRNA of the SC marker sex-determining region Y-box 9 (SOX9) instead of the Leydig cell marker StAR. Immunocytochemically, they are positive of SOX9, GATA binding protein 4, and androgen-binding protein. Conclusion: The SCs were enriched from the testicular tissues of prepubertal New Zealand rabbits by a simple and effective protocol, which provides a basis for further theoretical researches and practical applications.

Abstract
Germplasm cryopreservation and expansion of gonocytes/prospermatogonia or spermatogonial stem cells (SSCs) are important; however, it's difficult in cattle. Since inhibitors of Mek1/2 and Gsk3β (2i) can enhance pluripotency maintenance, effects of 2i-based medium on the cultivation of bovine prospermatogonia from the cryopreserved tissues were examined. The testicular tissues of newborn bulls were well cryopreserved. High mRNA levels of prospermatogonium/SSC markers (PLZF, GFRα-1) and pluripotency markers (Oct4/Pouf5, Sox2, Nanog) were detected and the PLZF+ /GFRα-1+ prospermatogonia were consistently identified immunohistochemically in the seminiferous cords. Using differential plating and Percoll-based centrifugation, 41.59% prospermatogonia were enriched and they proliferated robustly in 2i medium. The 2i medium boosted mRNA abundances of Pouf5, Sox2, Nanog, GFRα-1, PLZF, anti-apoptosis gene Bcl2, LIF receptor gene LIFR and enhanced PLZF protein expression, but suppressed mRNA expressions of spermatogonial differentiation marker c-kit and pro-apoptotic gene Bax, in the cultured prospermatogonia. It also alleviated H2 O2 -induced apoptosis of the enriched cells and decreased histone H3 lysine (K9) trimethylation (H3K9me3) and its methylase Suv39h1/2 mRNA level in the cultured seminiferous cords. Overall, 2i medium improves the cultivation of bovine prospermatogonia isolated from the cryopreserved testes, by inhibiting Suv39h1/2-mediated H3K9me3 through Mek1/2 and Gsk3β signalling, evidencing successful cryopreservation and expansion of bovine germplasm.

Abstract
Sertoli cells (SC) have important functions in spermatogenesis by regulating development of spermatogenic cells. Glial cell line-derived neurotrophic factor (GDNF) are produced by SC. Although the effects of GDNF on spermatogenesis have been well studied, the understanding of how GDNF is synthesized is still limited, especially in food animal producing species. Because protein kinase (PK) has varied functions in multiple cellular processes and the PK pathway modulates SC functions, the objective of the present study was to determine whether PK modulates the abundance of GDNF protein in SC of cattle. To conduct this study, immature SC were enriched from cryopreserved testicular tissues of 1-day-old bulls. These cells had a marked proliferation capacity. Results from immunostaining analysis indicated that there was a sustained abundance of SC mRNA marker protein transcripts and marker proteins: androgen bind protein (ABP), GATA4 and VIMENTIN. There was subsequent characterization of SC treated with the PK inhibitor staurosporine for 0, 1 or 2 h. Results from real-time-PCR and Western blot analyses indicated the treatment (2 h) resulted in a decrease in Gdnf mRNA transcript and GDNF protein. Additionally, the staurosporine treatment resulted in an increase in the abundance of anti-apoptosis Bcl2 and decrease in pro-apoptosis Bax mRNA transcripts. Furthermore, results of the TUNEL assay indicated there was a decrease in apoptosis in the staurosprine-treated SC. Collectively, results indicate the PK signaling is involved in regulation of GDNF protein abundance in the immature SC and the survival of these cells in cattle.

Abstract
Parkinson's disease (PD) is associated with olfactory defects in addition to dopaminergic degeneration. Dopaminergic signalling is necessary for subventricular zone (SVZ) proliferation and olfactory bulb (OB) neurogenesis. Alpha-synuclein (α-syn or Snca) modulates dopaminergic neurotransmission, and SNCA mutations cause familial PD, but how α-syn and its mutations affect adult neurogenesis is unclear. To address this, we studied a bacterial artificial chromosome transgenic mouse expressing the A30P SNCA familial PD point mutation on an Snca-/- background. We confirmed that the SNCA-A30P transgene recapitulates endogenous α-syn expression patterns and levels by immunohistochemical detection of endogenous α-syn in a wild-type mouse and transgenic SNCA-A30P α-syn protein in the forebrain. The number of SVZ stem cells (BrdU+GFAP+) was decreased in SNCA-A30P mice, whereas proliferating (phospho-histone 3+) cells were decreased in Snca-/- and even more so in SNCA-A30P mice. Similarly, SNCA-A30P mice had fewer Mash1+ transit-amplifying SVZ progenitor cells but Snca-/- mice did not. These data suggest the A30P mutation aggravates the effect of Snca loss in the SVZ. Interestingly, calbindin+ and calretinin (CalR)+ periglomerular neurons were decreased in both Snca-/-, and SNCA-A30P mice but tyrosine hydroxylase+ periglomerular OB neurons were only decreased in Snca-/- mice. Cell death decreased in the OB granule layer of Snca-/- and SNCA-A30P mice. In the same region, CalR+ numbers increased in Snca-/- and SNCA-A30P mice. Thus, α-syn loss and human A30P SNCA decrease SVZ proliferation, cell death in the OB and differentially alter interneuron numbers. Similar disruptions in human neurogenesis may contribute to the olfactory deficits, which are observed in PD.

Abstract
Bovine bone marrow mesenchymal stem cells (bBMSC) are potential stem cell source which can be used for multipurpose. However, their application is limited because the in vitro maintenance of these cells is usually accompanied by aging and multipotency losing. Considering transforming growth factor-β (TGF-β) pathway inhibitor Repsox is beneficial for cell reprogramming, here we investigated its impacts on the maintenance and differentiation of bBMSC. The bBMSC were enriched and characterized by morphology, immunofluorescent staining, flow cytometry, and multilineage differentiation. The impacts of Repsox on their proliferation, apoptosis, cell cycle, multipotency, and differentiation were examined by Cell Counting Kit-8 (CCK-8), real-time polymerase chain reaction, induced differentiation and specific staining. The results showed that highly purified cluster of diffrentiation 73+ (CD73 + )/CD90 + /CD105 + /CD34 - /CD45 - bBMSC with adipogenic, osteogenic, and chondrogenic differentiation capacities were enriched. Repsox treatments (5 μM, 48 hr) enhanced the messenger RNA mRNA levels of the proliferation gene (telomerase reverse transcriptase [ TERT]; basic fibroblast growth factor [ bFGF]), apoptosis-related gene ( bax and Bcl2), antiapoptosis ratio ( Bcl2/bax), and pluripotency marker gene ( Oct4, Sox2, and Nanog), instead of changing the cell cycle, in bBMSC. Repsox treatments also enhanced the osteogenic differentiation but attenuated the chondrogenic differentiation of bBMSC, concomitant with decreased Smad2 and increased Smad3/4 expressions in TGF-β pathway. Collectively, inhibiting TGF-β/Smad signaling by Repsox regulates the in vitro maintenance and differentiation of bBMSC.
