Analysis of spermatogonial stem cells (SSCs) at various time points following withdrawal and replacement of glial cell line-derived neurotrophic factor (GDNF) and GDNF-family receptor alpha-1 (GFRalpha1). Results provide insight into the mechanisms of GDNF-supported in vitro self-renewal of SSCs.

(Submitter supplied) GDNF-regulated gene expression was studied in cultures of actively self-renewing spermatogonial stem cells established from 6 day old male mice. GDNF is the essential growth factor regulating mouse spermatogonial stem cell self-renewal. Using a serum-free chemically defined culture system that supports mouse spermatogonial stem cell self-renewal for extended periods of time, GDNF-regulated genes were identified using microarray profiling. more...

(Submitter supplied) Expression of GDNF-regulated genes was studied in cultures of self-renewing rat spermatogonial stem cells established from 8-10 day old rat pups maintained in a defined serum free medium. GDNF is the primary regulator of spermatogonial stem cell self renewal in the rat. GDNF regulated genes were identified using microarray profiling rat spermatogonial stem cells in the presence and absence of GDNF.

(Submitter supplied) Insight into mechanisms controlling gene expression in the spermatogonial stem cell (SSC) will improve our understanding of the processes regulating spermatogenesis and aid in treating problems associated with male infertility. In this study we explored the global gene expression profiles of glial cell line-derived neurotrophic factor (GDNF) regulated transcription factors, Ets variant gene 5 (Etv5), B-cell CLL/lymphoma 6, member B (Bcl6b) and POU domain, class-3 transcription factor-1 (Pou3f1). more...

(Submitter supplied) Self-renewal and differentiation of spermatogonial stem cells (SSCs) provides the foundation for testis homeostasis, yet mechanisms that control their functions in mammals are poorly defined. We used microarray transcript profiling to identify specific genes whose expression are augmented in the SSC-enriched Thy1+ germ cell fraction of mouse pup testes. Comparisons of gene expression in the Thy1+ germ cell fraction to the Thy1-depeleted testis cell population identified 202 genes that are expressed 10-fold or higher in Thy1+ cells. more...

(Submitter supplied) Objectives: Fibroblast growth factor 9 (FGF9) is expressed by somatic cells in the seminiferous tubules, yet little information exists about its role in regulating spermatogonial stem cells (SSCs). Materials and Methods: Fgf9 overexpression lentivirus was injected into mouse testes, and PLZF immunostaining was performed to investigate the effect of FGF9 on spermatogonia in vivo. Effect of FGF9 on SSCs was detected by transplanting cultured germ cells into tubules of testes. more...

(Submitter supplied) The primary spermatogonial stem cells (SSCs), which arise from gonocytes during neonatal development, serve as a foundational self-renewing reservoir to ensure continuous production of spermatozoa throughout adulthood. The transformation of gonocytes into SSCs takes place in a niche established by Sertoli cells. To date, the factors that guide Sertoli cells to establish the initial stem cell niche remain largely unknown. more...

(Submitter supplied) In the normal adult testis GDNF specifically targets spermatogonial stem cells and early progenitor spermatogonia. Inhibition of GDNF signaling for 9 days alters only 171 of the 15,000 transcripts expressed in the mouse testis. Many of these transcripts are known to be expressed by the spermatogonial stem cells. One transcript that is affected is Kif26A, a known suppressor of GDNF signaling.

(Submitter supplied) MicroRNAs (miRs) play a key role in the control of gene expression in a wide array of tissue systems where their functions include the regulation of self-renewal, cellular differentiation, proliferation, and apoptosis. However, the functional importance of individual miRs in controlling spermatogonial stem cell (SSC) homeostasis has not been investigated. Using high-throughout sequencing, we profiled the expression of miRs in the Thy1+ testis cell population, which is highly enriched for SSCs, and the Thy1- cell population, composed primarily of testis somatic cells. more...

(Submitter supplied) Spermatogonial stem cells (SSCs) provide foundation for spermatogenesis by undergoing continuous self-renewal division. Previous studies have reported conflicting results on the role of the pituitary gland activity in SSC self-renewal. In this study, we analyzed the role of hormonal regulation of SSCs using Lhcgr (luteinizing hormone/choriogonadotropin receptor) knockout mice. Analysis of gene expression profiles showed that testes of Lhcgr-deficient mice exhibit significantly enhanced Wnt5a expression in Sertoli cells. more...

(Submitter supplied) The spermatogonial stem cells (SSCs) niche is critical for SSC maintenance and the subsequent spermatogenesis. Numerous reproductive hazards impair the SSC niche, thereby result in aberrant SSC self-renewal and male infertility. However, promising agents targeting the impaired SSC niche to promote SSC self-renewal are still limited. Here, we screen out and assess the effects of Lovastatin on the self-renewal of mouse spermatogonial stem cells (mSSCs). more...

(Submitter supplied) Testis immune privilege is thought to be mediated by somatic cells. However, it is not strong enough to protect allogeneic spermatogonial stem cells (SSCs) transplanted into the seminiferous tubules. Here we report successful production of allogeneic offspring by inducing PD-L1 in SSCs. Activation of self-renewal division induced PD-L1 and B7-H3 expression in cultured SSCs, which produced sperm after allogeneic transplantation. more...
