Project description:A 1.5-year-old healthy male Hu sheep was selected and castrated for testis collection, then single cell suspension was obtained using enzymatic digestion method for single cell sequencing. And the cell types of sheep testis and marker genes of each cell type were identified based on the RNA sequencing.
Project description:A 6-month-old healthy male Hu sheep was selected and castrated for testis collection, then single cell suspension was obtained using enzymatic digestion method for single cell sequencing. And the cell types of sheep testis and marker genes of each cell type were identified based on the RNA sequencing.
Project description:Sheep testes undergo a dramatic rate of development with structural changes during sexual maturity, including the proliferation and maturation of somatic niche cells and the initiation of spermatogenesis. To explore this complex process, 12,843 testicular cells from three sexual maturity (3 month-old) rams were sequenced using 10x Genomic platform single-cell sequencing (scRNA-seq).Nine testicular somatic cell types and five male germ cell types were observed.The study revealed significant changes in germline stem cells during sexual maturation. Candidate factors and pathways for the regulation of germ and somatic cell development were identified that represent the scientific basis for the development of a livestock stem cell breeding program.
Project description:To reveal distinct transcriptomes associated with spermatogonial stem cell renewal vs. initiation of differentiation, single-cell transcriptomes from P6 ID4-EGFP+ spermatogonia (sorted for brightest or dimmest) or unselected testis cells were used for Drop-Seq analysis. The GFP-bright and dim phenotypes exhibit distinct fates when assayed by transplantation, with ID4-EGFPbright cells highly enriched for SSCs, and ID4-EGFPdim cells enriched for progenitors. We used the 10x Genomics Chromium (a commercial Drop-Seq variant) to perform single-cell RNA-seq
Project description:Testis is the most important male reproductive organ, and the integrity of its physiological function is crucial to the successful production of sperm. In this study, the expression profiles of 11 991 and 8 930 cells in testicular tissue of yak and cattle-yak after sexual maturity were established using Single-cell RNA sequencing. The identification results of cell subpopulations and marker genes were analyzed and their possible mechanisms were predicted.
