This study was performed to investigate the stimulating effect on oocyte maturation and cumulus cell expansion in TC199 media by human cord serum (HCS) supplementation. Immature mouse oocyte cumulus complexes (OCCs) were cultured in TC199 media supplemented with bovine serum albumin (BSA), HCS and human chorionic gonadotropin (hCG) instead of luteinizing hormone (LH) respectively, and the expression of cumulus expansion and oocyte maturation were observed. After 4hr and 24hr culture with or without OCCs, media containing 0.4% BSA, 10% HCS and 10 lU hCG respectively were collected and analyzed for changing concentrations of estradiol (E2), progesterone(P4), testosterone(T), and PGF2. There were no elevation of E2, T, and PGF2 by OCCs culture, but minute elevation of P4 level by 24hr OCCs culture in hCG supplementation (p=0.048). The stimulating pattern of cumulus expansion of OCCs by HCS and hCG supplementation was similar to our previously report using Ham's F-10 media, however oocyte maturation rates after 24hr OCCs culture in all media were increased by 20~30% compared to Ham's F-10 media. These results suggest that LH in HCS induce cumulus expansion probably by P4 secretion of OCCs, and TC199 is efficient media for immature mouse oocyte maturation.
