| Description |
Normal ovarian development is necessary for the production of healthy oocytes. However, the characteristics of oocytes development at different stages and the regulatory relationship between oocytes and somatic cells have not been accurately resolved. Here, we performed scRNA-Seq, as well as spatial transcriptomic sequencing to profile the ovarian transcriptome atlas in rat. We identified four components of developing granulosa cell (GC) including cumulus, primitive, mural, and luteal cells and constructed their differential transcriptional regulatory networks. Several undiscovered growth signalings were identified from oocytes to cumulus cells, such as Jag1/Notch2 and Fgf9/ Fgfr2. Moreover, we described three cumulus sequential phases with follicle development and determined key transcriptional factors in each cumulus phases. We also pinpointed that macrophages may involve in luteal regression. Altogether, The single-cell spatial transcriptomic profile of the ovary provide a new research dimension for temporal and spatial analysis of ovarian development. It is also provided an important data resources and research basis for in-depth excavation of the mechanisms of mammalian ovary development. |
