RESUMEN
Extracellular vesicles (EV),nanoscale vesicles encapsulated by phospholipid bilayers,are rich in biological molecules such as nucleic acids,metabolites,proteins,and lipids derived from parental cells.They are mainly involved in intercellular communication,signal transmission,and material transport and affect the functions of target cells.Ovulation disorders account for a higher proportion in the factors causing infertility which demonstrates increasing incidence year by year.Non-coding RNAs participate in a series of physiological and pathological processes of follicular development,playing a key role in female infertility.This review systematically introduces the types and biological roles of EV and elaborates on the regulation of follicular development from the effects of EV and non-coding RNAs on granulosa cell function,oocyte maturation,ovulation,luteal formation,and steroid hormone synthesis,providing a new idea and a breakthrough point for the diagnosis and treatment of infertility.
