Project description:To examine the transcriptome of early testicular somatic cells during gonadogenesis at 12.5dpc RNA sequencing (RNA-Seq) was performed on murine primary testicular cell lineages isolated from the Sf1-eGFP line by FACS. The three main somatic cell lineages of the testis were isolated: the Sertoli cells which direct male development; the fetal Leydig cells (FLCs) that produce steroid hormones and virilise the XY individual and a heterogenous population of interstitial cells, some of which give rise to the adult Leydig cells (ALCs). This dataset provides a platform for exploring the biology of FLCs and understanding the role of these cells in testicular development and masculinization of the embryo, and a basis for targeted studies designed to identify causes of idiopathic XY DSD. RNA-Seq of 3 enriched cell populations from 12.5dpc mouse gonad (Sertoli cells, Leydig cells and Interstitial cells isolated by FACS-sorting) on an Illumina HiSeq 1500, in triplicate.

Project description:BACKGROUND: Phthalates are manmade industrial additives used mostly as plasticizers. In addition to their deleterious effects on male genital development, population studies have recently documented correlations between phthalates exposure and subtle impacts on reproductive tract development and on the metabolic syndrome in male adults. In mature rodents liver di-(2-ethylhexyl)-phthalate (DEHP) activates the peroxisome proliferators-activated receptor (PPARalpha), a member of the nuclear receptor (NR) superfamily. OBJECTIVES: Using a systems biology approach, we aimed at defining potential mechanisms underlying the impacts of DEHP on adult mouse liver and testis. METHODS: Thus, we performed a parallel analysis of transcript and metabolic profiles in the liver from adult mice exposed to varying DEHP doses. Moreover, we obtained pangenomic mRNA profiles of laser-captured Leydig and Sertoli cells from mature animals exposed to DEHP. RESULTS: Hepatic genes modulated by DEHP are predominantly PPARalpha targets. However, the induction of some prototypic cytochrome P450 genes strongly supports the activation of additional NR pathways. Integration of hepatic transcriptomic and metabonomic profiles further revealed a correlation between the impacts of DEHP on a cluster of genes and metabolites linked to heme synthesis and on a cluster of Rev-erbalpha target genes related to metabolic and circadian clock pathways. Cell-specific effects of DEHP were investigated in the adult testis and a noticeable impact of DEHP was observed on Leydig cells transcriptome. CONCLUSIONS: We report a detailed analysis of DEHP interference with hepatic Constitutive Androstane Receptor (CAR) and Rev-erbalpha pathways and a novel transcriptional impact of DEHP on adult endocrine cells of the testis. Experiment Overall Design: two condition experiment, Leydig cells from DEHP-treated mice vs. Leydig cells from vehicle-treated mice. Biological replicates: 2 DEHP-treated samples and 3 vehicle-treated samples. Each treated sample has been hybridized against each vehicle-treated sample in a dye-swap design.

Project description:Leydig cells (LCs) are the primary androgen producing cells in males throughout development and appear in chronologically distinct populations; fetal Leydig cells (FLCs), neonatal LCs and adult Leydig cells (ALCs). ALCs are responsible for progression through puberty and for maintenance of reproductive functions in adulthood. In patients with reproductive problems, such as infertility or testicular cancer, and especially in men with high gonadotrophin levels, LC function is often impaired, and LCs may cluster abnormally into hyperplastic micronodules. The purpose of this study was to investigate whether ALCs within hyperplastic micronodules display characteristics of FLCs. Transcriptome profiling was performed on LCs microdissected from 12 frozen human tissue samples, including morphologically normal foetal (gestational week 10-11) and adult testis samples, and adult specimens with LC micronodules or LC micronodules adjacent to chorionic gonadotrophin (hCG)-producing testicular germ cell tumours. Fifteen additional foetal and adult testis tissue specimens were used for validation of the expression data at the protein level. The study revealed the the gene expression profiles of FLCs and all ALC subgroups were clearly different, but there were no significant differences in expressed genes between the normally clustered and hyperplastic ALCs. Close similarity between transcriptome profiles of the normally clustered and hyperplastic ALCs suggest that the changes in LC function and morphology observed in patients with reproductive disorders possibly reflect subtle changes in the expression of many genes rather than regulatory changes of single genes or pathways. The transcriptome of FLCs revealed several genes not known previously to be expressed in this cell type during early development, including SULT2A1, WISP2, HPGD, and IGF2BP1, and their expression changes were validated at the protein level.

Project description:Whereas the human fetal immune system is poised to generate immune tolerance and suppress inflammation in utero, an adult-like immune system emerges to orchestrate anti-pathogen immune responses in post-natal life. It has been posited that cells of the adult immune system arise as a discrete ontological “layer” of hematopoietic stem-progenitor cells (HSPCs) and their progeny; evidence supporting this model in humans has, however, been inconclusive. Here, we combine bulk and single-cell transcriptional profiling of lymphoid, myeloid, and HSPCs from fetal, perinatal, and adult developmental stages to demonstrate that the fetal-to-adult transition occurs progressively along a continuum of maturity—with a substantial degree of interindividual variation at the time of birth—rather than via a transition between discrete waves. These findings have important implications in the design of strategies for prophylaxis against infection in the newborn, and for the use of umbilical cord blood (UCB) in the setting of transplantation. Naïve CD4 and CD8 T cells, and CD34+ hematopoietic stem and progenitor cells (HSPCs) were isolated from human samples of three different groups: Fetal (18-23 gestational weeks), full-term newborn (37+ gestational weeks at birth), and adults age 23 to 53. For each group, five independent donors were analyzed, but not all cell types could be sequenced for every patient.
