Endometriotic mesenchymal stem cells promote the fibrosis process of endometriosis through paracrine TGF‐β1 mediated RASAL1 inhibition

Endometrial-derived stem cells are key players in endometriosis (EMs) pathogenesis, while the mechanism involved is still unclear. Herein, the role and regulatory mechanism of endometriotic mesenchymal stem cells (ecto-MSCs) in regulating fibrosis during EMs progression were investigated.
