Variation of cholesterol contents in porcine cumulus-oocyte complexes is a key factor in regulation of fertilizing capacity.

Abstract

The aims were to explore substances affecting maturation of porcine oocytes and effects of cholesterol efflux by methyl-β-cyclodextrin (MBCD). Cumulus-oocyte complexes (COCs) were collected from ovaries with or without corpora lutea (CL). Ovarian cholesterol content was determined and histologic sections were prepared for immunostaining of lanosterol 14… (More)
