Single-cell RNA-sequencing of bovine fetal gonads using 10x Genomics

Project description:The germ cell lineage ensures the creation of new individuals perpetuating the genetic information across generations. Primordial germ cells (PGCs) are pioneers of gametes and exist transiently during development until they differentiate into oogonia in females, or spermatogonia in males. Little is known about the molecular characteristics of PGCs in cattle. By performing single-cell RNA-sequencing of bovine fetal gonads we evaluated the molecular signatures of bovine germ cells and their niche at 50 days of development. Our results indicate that PGCs and somatic cells were in very early stages of development, and that bovine and human germ cells share expression of transcriptional regulators of germline specification, and several genes coding for membrane-bound proteins. Additionally, the expression of members of Notch, Nodal/Activin, and BMP signaling cascades in the bovine fetal ovary, suggests that these pathways are involved in the interaction between germ cells and their niche. Results of this study provide insights into the mechanisms involved in the development of bovine PGCs and put in evidence similarities between the bovine and human germline.

Single-cell analysis of fetal human gonads (male and female) using 10X genomics

Project description:Single cell transcriptomic analyses are increasingly being employed to study human developmental processes in the gonad to advance our understanding of human gametogenesis. However, to date, these analyses have primarily focused on germ cells, while the somatic niche has been largely overlooked. Moreover, a comparative transcriptomic analysis of both female and male early gonad development on the single cell level is currently lacking. We performed single cell RNA-Seq on whole human fetal gonads from first and second trimester, both from male and female. We define gene expression profiles, which include novel marker genes, of major gonadal somatic cell types and validate them on the protein level. We identify the genetic signature of early human male rete cells, both in male and in female gonads. Overall, our study provides an in-depth molecular characterization of both male and female somatic cell types in early fetal gonads.

Expression analysis of Wv/Wv fetal gonads

Project description:Following sex determination, XY and XX gonads develop into a testis and an ovary, respectively. Depending on the sex of the gonad, resident germ cells will subsequently be committed to either spermatogenesis or oogenesis. In this study we took advantage of the Wv/Wv mouse genetic model, in which gonads are almost devoided of germ cells, to uncover gene expression underlying fetal germ cell development. Male and Female gonads were collected at 12, 14 and 16 days post coitum (dpc) from wild-type and Wv/Wv mouse embryos. Total RNAs were extracted and hybridized on Affymetrix microarrays. Expression signals from male and female gonads or from wild-type and mutant gonads were compared to identify sexually dimorphic genes as well as genes expressed in germ cell during fetal gonad development.

Reconstructing the human first trimester fetal-maternal interface using single cell transcriptomics - 10x data

Project description:To explore the interactions between the range of maternal and fetal placental cell types present, we profiled the transcriptomes of more than 50,000 single cells from matched first trimester samples of maternal blood and decidua, as well as fetal cells from the placenta itself. RNA-seq was done using the standard 10x chromium v2 chemistry.

A spatiotemporal regulatory network for steroidogenesis of human fetal adrenal glands and gonads

Project description:Human fetal adrenal glands are huge endocrine organ, produce prodigious quantities of dehydroepiandrosterone and its sulfate (DHEA/DHEAS), which is the most prominent precursor for steroid hormones, adrenal gonads dysfunction leads to states of virilization or effemination. However, for a long time the function of fetal adrenal in initial sex differentiation is unclear. Herein, we draw out a single-cell transcriptional landscape of human fetal adrenals and gonad from 6 to 14 gestational weeks (GW). We found that the adrenal glands begin to express CYP17A1 steroid-related enzyme much early than testis, subsequent testis steroid express pattern support de novo or halfway testosterone synthesis. Excepted steroidogenic cell, notably, the immune cells or neurocyte shows steroid metabolism or regulation ability, such as CD5L+ macrophage interacted with steroidogenic cell and SRD5A1+ AKR1C2+ chromaffin cells synthesis active testosterone DHT through backdoor pathway. Sex different were found at adrenal glands and gonad development: there is a small HSD3B2 peak occurs only in female adrenal glands around 10-12 GW within the time window of sex differentiation. SST expression levels or SST+ cells quantity in adrenal glands and gonads are different in two gender. Our research indicates that a sex different in spatial and temporal disparities steroidogenic regulatory networks in adrenal glands and gonads, facilitating further exploration of development and physiology of human adrenal glands.
