Project description:The cell identities of CD49f+GSCs were further identified by comparing them with the E11.5 PGCs and P2 GSCs. The transcriptomic analysis revealed that the CD49f+GSCs had 1/3 similar genes profile to the E11.5 PGCs and P2 GSCs. Further gene ontology (GO) analysis demonstrated that the E11.5 PGCs, P2 GSCs, and CD49f+GSCs shared the partial similar gene expression profile of pluripotency regulation signaling pathway, PI3K-AKT signaling, chemokine signaling, and HIF-1 signaling.
Project description:To gain insight into the role of Runx3 in TrkC neurons we performed RNA-seq on E11.5 TrkC neurons isolated from cervical ganglia of Runx3-P2+/- and Runx3-P2-/- mice
Project description:The present investigation was to identify transcriptomic changes of control and Dnd1-cKO PGCs at E11.5 by RNA-seq analysis. We identified 181 upregulated and 141 downregulated genes in Dnd1-cKO PGCs.
Project description:We have characterized by small-RNAseq the miRNA expression pattern of mouse male and female Primordial Germ Cells (PGCs) and somatic stromal cells from gonads at E11.5, E12.5 and E13.5. MiRNA accumulation was higher in somatic cells than in PGCs and more stable across the different developmental stages analyzed. Differential expression analyses showed differences in the regulation of key miRNA clusters such as miR-199-214, miR-182-183-96 and miR-34c-5p whose targets have defined roles in both germ and somatic cells in gonadal sexual determination. Extensive analyses of miRNA sequences revealed an increase in non-canonical isoforms in PGCs at E12.5 compared to E11.5 and E13.5 and a dramatic change in isomiR expression and non-template 3' nucleotide additions in female PGCs at E13.5 respect to the other samples.
Project description:To elucidate the molecular mechanisms by which PGCs become pluripotent cells, we performed whole transcriptome analysis during the conversion of PGCs into EGCs. There are 3 groups of gene expression profiles, time course analysis of PGCs to EGCs, forced expression of germ cell genes in ESCs, and chemical treatment of PGCs at day2 of the culture
Project description:We profiled a time-course single-cell RNA-seq on C57BL/6 mouse ovary from E11.5 to E14.5 to study the cell population heterogeneity and regulation of meiosis initiation. We collected single cell from XX gonads at E11.5, E12.5, E13.5 and E14.5, and were further captured with 10x Genomics based single-cell system. By using single-cell RNA seq, we recapitulated the progression of meiosis using pseudotime ordering of all germ cells and delineated key molecular network among all germ cell clusters. Besides, we provide candidate meiosis stage-specific master regulons along the progression of meiosis and provide detailed transcriptome profile information for controversial Xist+ PGCs. Our data here offers the opportunity for exploring mechanisms underlying germ cell meiosis progression at single cell resolution.
Project description:The growth factors and signaling pathways that are essential for the inducing proliferation of chicken PGCs is unclear. We investigated the effect of basic fibroblast growth factor (bFGF) on the survival and proliferation of PGCs under feeder-free conditions. We used microarrays to examine the genes regulated by bFGF treatment in chicken PGCs. Cultured PGCs were collected before and after withdrawal of bFGF for 24 h, and 24 h after bFGF replacement. The RNA was extracted and hybridized on Affymetrix microarrays. Three replicates each.
