GSE136441: Single-cell analysis RNA sequencing of prenatal and neonatal gonads/ovaries at E11.5, E12.5, E14.5, E16.5, E18.5, P1 and P5

• Organsim mouse
• Type RNASEQ
• Target gene

We sequenced more than 52,500 single cells from E11.5 to P5 gonads to analyze primordial follicles and wave 1 medullar follicles during mouse fetal and perinatal oogenesis. Germ cells clustered into six meiotic substages as well as dying/nurse cells. We also define genes expressed by epithelial progenitors, and clarify the similar but distinct genetic programs of bipotential-derived and epithelial-derived pre-granulosa cell progenitors. Their differentially expressed genes are candidates to control the distinctive developmental programs of wave 1 and wave 2 follicles. These observations provide a strong basis for further studies of the development, physiology, and evolutionary conservation of mammalian ovarian follicle formation.
