Abstract
|
|
|
|
The study was conducted to investigate on in vitro developmental rates of bisected bovine embryos co-culture in 10% FCS＋TCM-199 media containing hormones, oviductal epithelial cells and cumulus cells 0 to 7 days after bisection. In vitro developmental rates was defined as development rates on in vitro culture or FDA-test. The results are summarized as follows : 1. In vitro developmental rates of bisected bovine embryos co-cultured in 10% FCS＋TCM-199 media containing PMSG＋hCG, PMSG＋beta-estradiol, hCG＋beta-estradiol, PMSG, hCG 0 to 3 days and 4 to 7 days were 16.7~30.0% and 11.1~25.0%, respectively. In vitro developmental rates of bisected embryos co-cultured in 10% FCS＋TCM-199 media containing hormones significantly higher than that of non co-culture. 2. In vitro developmental rates of bisected bovine embryos co-cultured 10% FCS＋TCM-199 media containing oviductal epithelial cells 0 to 3 days and 4 to 7 days were 25.0% and 22.2%, respectively.
