Project description:Sertoli cells are essential nurse cells in the testis that regulate the process of spermatogenesis and establish the immune-privileged environment of the blood-testis-barrier (BTB). The induction of human Sertoli cells from fibroblasts could provide cellular sources for fertility and transplantation treatments. Here, we report the in vitro reprogramming of human fibroblasts to Sertoli cells and characterize these human induced Sertoli-like cells (hiSCs). Initially, five transcriptional factors (NR5A1, GATA4, WT1, SOX9 and DMRT1) and a gene reporter carrying the AMH promoter were utilized to obtain the hiSCs. We further reduce the number of reprogramming factors to two, i.e., NR5A1 and GATA4, and show that these hiSCs have transcriptome profiles that are similar to those of primary human Sertoli cells. Consistent with the known cellular properties of Sertoli cells, hiSCs attract endothelial cells and exhibit high number of lipid droplets in the cytoplasm. More importantly, hiSCs can sustain the viability of spermatogonia cells harvested from mouse seminiferous tubules. In addition, hiSCs suppress the production of IL-2 and proliferation of human T lymphocytes. When hiSCs were cotransplanted with human embryonic kidney cells, these xenotransplanted human cells survived longer in mice with normal immune systems. hiSCs also allow us to determine a gene associated with Sertoli-only syndrome (SCO), CX43, is indeed important in regulating the maturation of Sertoli cells.

Project description:To compare the the genomic profile of MEFs, immature Sertoli, mature Sertoli cells, and MEFs (NWD) after infection of Nr5a1, Wt1 and Dmrt1 after 1 month of dox exposure. MEFs (NWD) were infected with Nr5a1, Wt1 and Dmrt1 and were exposed to dox for 1 month. MEFs, immature Sertoli and mature Sertoli cells were cultured for 3 days and collected

Project description:The effects of Gata4 inhibition on global gene expression in TM4 Sertoli cells was analyzed. Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Sertoli cell line TM4. Among the downregulated genes were regulators of blood-testtis barrier function and lactate metabolism. TM4 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted.

Project description:The effects of Gata4 inhibition on global gene expression in TM4 Sertoli cells was analyzed. Using microarray analysis we identified a set of genes that are downregulated or upregulated following siRNA-mediated silencing of Gata4 in the murine Leydig tumor cell line mLTC-1. Among the downregulated genes were enzymes of the androgen biosynthetic pathway. TM4 cells were transfected with non-targeting (NT) siRNA and Gata4 siRNA respectively. 72h post transfection cells were lysed and RNA was extracted. n=3 of each sample group; control samples are samples 3-6 (TM4 cells treated with non-targeting siRNA)

Project description:To investigate the role of the nuclear receptor NR5A1 in testis after sex determination, we have analyzed mice lacking NR5A1 in Sertoli cells (SC) from embryonic day (E) 13.5 onwards. Ablation of Nr5a1 impairs the expression of genes characteristic of the SC identity (e.g., Sox9, Amh), causes SC death from E14.5 through a Trp53-independent mechanism related to anoikis, and induces disorganization of the testis cords. Together, these effects cause germ cells to enter meiosis and die. Single-cell RNA-sequencing experiments revealed that NR5A1-deficient SC change their molecular identity: some acquire a “pre-granulosa-like” identity, while other revert to a “supporting progenitor-like” cell identity, most of them being “intersex” because they express both testicular and ovarian genes. Fetal Leydig cells (LC) do not display significant changes, indicating that SC are not required beyond E14.5 for their emergence or maintenance. In contrast, adult LC were absent from the postnatal testes. In addition, adult mutant males display persistence of Müllerian duct derivatives, decreased anogenital distance and reduced penis length, which can be explained by the loss of AMH and testosterone synthesis due to SC failure.

Project description:Nuclear receptor subfamily 5 group A member 1 (NR5A1) encodes steroidogenic factor 1 (SF1), a key regulatory factor that determines gonadal development and coordinates endocrine functions. Here, we have established a stem cell-based model of human gonadal development and applied it to evaluate the effects of NR5A1 during the transition from bipotential gonad to testicular cells. We combined directed differentiation of human induced pluripotent stem cells (46,XY) with activation of endogenous NR5A1 expression by conditionally-inducible CRISPR activation. The resulting male gonadal-like cells expressed several Sertoli cell transcripts, secreted anti-Müllerian hormone and responded to follicle-stimulating hormone by producing sex steroid intermediates. These characteristics were not induced without NR5A1 activation. A total of 2691 differentially expressed genetic elements, including both coding and non-coding RNAs, were detected immediately following activation of NR5A1 expression. Of those, we identified novel gonad-related putative NR5A1 targets, such as SCARA5, which we validated also by immunocytochemistry. In addition, NR5A1 activation was associated with dynamic expression of multiple gonad- and infertility-related differentially expressed genes. In conclusion, by combining targeted differentiation and endogenous activation of NR5A1 we have for the first time, been able to examine in detail the effects of NR5A1 in early human gonadal cells. The model and results obtained provide a useful resource for future investigations exploring the causative reasons for gonadal dysgenesis and infertility in humans.

Project description:The nuclear receptor subfamily 5 group A member 1 (NR5A1), encoding steroidogenic factor 1 (SF-1), has been identified as a critical factor in gonadal development in animal studies. A previous study of ours suggested that upregulation of NR5A1 during early gonadal differentiation in male (46,XY) human pluripotent stem cells steers the cells into a more mature gonadal cell type. However, the detailed role of NR5A1 in female gonadal differentiation has yet to be determined. In this study, by combining the processes of gonadal differentiation and conditional gene activation, we show that NR5A1 induction predominantly upregulates the female gonadal marker inhibin subunit α (INHA) and steroidogenic markers steroidogenic acute regulatory protein (STAR), cytochrome P450 family 11 subfamily A member 1 (CYP11A1), cytochrome P450 family 17 subfamily A member 1 (CYP17A1), hydroxy-delta-5-steroid dehydrogenase (HSD3B2) and hydroxysteroid 17-beta dehydrogenase 1 (HSD17B1). In contrast, NR5A1 induction did not seem to affect the bipotential gonadal markers gata binding protein 4 (GATA4) and Wilms tumour suppressor 1 (WT1) nor the female gonadal markers r-spondin 1 (RSPO1) and wnt family member 4 (WNT4). Differentially expressed genes were highly associated with adrenal and ovarian steroidogenesis pathways. Moreover, time-series analysis revealed different dynamic changes between male and female -induced samples, where continuously upregulated genes in female gonadal differentiation were mostly associated with adrenal steroidogenesis. Thus, in contrast to male gonadal differentiation, NR5A1 is necessary but not sufficient to steer human embryonic stem cell (hESC)-derived bipotential gonadal-like cells towards a more mature somatic, female cell fate. Instead, it seems to direct bipotential gonadal-like cells more towards a steroidogenic-like cell population. The information obtained in this study helps in elucidating the role of NR5A1 in gonadal differentiation of a female stem cell line.
