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
