Expression profiling by high throughput sequencingSummary
We have identified a Golgi- and microtubule-rich vesicular structure, termed “Visham”, which resembles the Drosophila fusome and accumulates asymmetrically during germ cell cyst divisions starting at E11.5. Genes associated with Visham become enriched in presumptive oocytes during cyst divisions and early meiosis, suggesting its role as a potential oocyte rejuvenation center. To investigate this further, we performed single-cell RNA sequencing (scRNA-seq) of mouse fetal germ cells at E10.5, E11.5, and E15.5, including developmental stages not previously covered in earlier datasets (GSE136441) and thus generated a composit dataset of E10.5-P5 germ cells. Additionally, we analyzed Dazl homozygous and heterozygous mutant ovarian germ cells at E11.5 and E12.5 to study the impact of Dazl loss on cyst formation and Visham-associated gene expression dynamics. This dataset provides a comprehensive resource to explore transcriptional changes across key stages of fetal ovarian development and in the context of Dazl function.
