Swiss Scientists Grow Shedding-Resilient Uterine Organoids for Research

Summary

Story summary

Swiss researchers created endometrium organoids that regenerate after shedding, mimicking uterine lining, in a Cell Stem Cell study published on 28 April.
They isolated epithelial cells from biopsies, embedded them in a matrix, used estrogen-progesterone cycles with withdrawal and breakdown to trigger shedding and regeneration.
Analysis showed luminal epithelial cells, not deep-tissue stem cells, drive repair, and the epithelial-only model may aid endometriosis research, Konstantina Nikolakopoulou and Deena Emera said.
