Abstract:The aim of this study was to verify the beneficial effects of different concentrations of epidermal growth factor (EGF) on survival and antrum formation of isolated ovine preantral follicles cultured in vitro. Ovine ovaries (n = 50) were collected from a local slaughterhouse and secondary follicles (150–200 μm in diameter), without antral cavities, were mechanically isolated by microdissection using 26-gauge needles. After selection, the follicles were individually cultured in 100-μL droplets of culture medium… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
