Organoid Transplantation Can Improve Reproductive Prognosis by Promoting Endometrial Repair in Mice.

OBJECTIVE

Intrauterine adhesion (IUA) is one of the major causes of refractory secondary infertility, especially in regions and countries with high abortion rates. In this study, we used the mouse IUA model to evaluate the feasibility of the organoids, a 3D cell structure derived from endometrial tissue, as grafts for the treatment of post-traumatic endometrial regeneration disorders.

METHODS

The isolated and cultured endometrial organoid was transplanted into the model IUA uterus by the hydrogel scaffold method.

RESULTS

The cultured endometrial organoids were transplanted into the basal layer of the damaged endometrium for 28 days. They were completely implanted and grew normally. They not only reconstructed the structural integrity of the endometrial epithelium but also realized the functional repair of the endometrium through differentiation cultures and secretory functions.

CONCLUSION

For severe IUA, this method may be better than stem cell transplantation. These findings provide useful insights into the use of endometrial organoid regeneration in the treatment of injury repair.
