PRC2 Inhibition Enables Self-Renewal of Chimpanzee Naive PSC
2026-06-09
Huang et al. (2025) demonstrate that targeted inhibition of the PRC2 complex overcomes a key barrier to the expansion and self-renewal of naive pluripotent stem cells (PSCs) from chimpanzee. This finding not only advances the derivation of primate stem cell models but also underscores the role of chromatin regulation in early pluripotency, with implications for comparative embryology and translational research.
