Researchers map turtle egg cell genes for conservation
PubMed · 2026-08-31
Scientists mapped the ovarian cells of the Chinese pond turtle at the single-cell level, identifying specific genes that mark egg cells and the support cells around them. This helps researchers understand turtle reproduction and could inform conservation efforts for this species.
1
Single-cell RNA sequencing identified major ovarian cell types in Mauremys reevesii, including granulosa cells and oocytes
2
WNT4 and WNT6 genes were identified as specific markers for granulosa cells
3
UCHL1 was identified as a marker for oocytes, with granulosa markers validated via dual-color in situ hybridization
