Single-cell RNA-seq of the developing C57BL/6 mouse ovary from E11.5 to E14.5

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. We totally analyzed ~20,000 single cell transcriptome profile from E11.5 to E14.5 XX gonads to reveal cellular heterogeneity during meiosis initiation stage.
