Advances in Human Umbilical Cord Mesenchymal Stem Cells-Derived Extracellular Vesicles and Biomaterial Assemblies for Endometrial Injury Treatment

Endometrial injury caused by repeated uterine procedures, infections, inflammation, or uterine artery dysfunction can deplete endometrial stem/progenitor cells and impair regeneration, thereby diminishing endometrial receptivity and evident
