The study was conducted to investigate on the survival rate of bisected porcine embryos co-cultured in 10% FCS(v/v)＋TCM-199 media containing hormones, oviductal epithelial cells and cumulus cells 0 to 72 hrs after bisection. In vitro survival rate was defined as development rate on in vitro culture or FDA-test. The results are summarized as follows ; 1. The survival rate of bisected porcine embryos cultrued in 10% FCS＋TCM-199 media contaning PMSG, hCG, PMSG＋hCG, hCG＋beta-estradiol 0 to 20 hrs and 20 to 40 hrs were 37.6% and 37.5%, 28.6% and 28.6%, 35.7% and 28.8%, 30.8% and 23.1%, 38.5% and 30.7%, respectively. The survival rate of bisected embryos co-cultured in TCM-199 media containing hormones, oviductal epithelial cells and cumulus cells was significantly higher than that of non co-culture. 2. The survival rate of bisected porcine embryos co-cultured 10% FCS＋TCM-199 media containing oviductal epithelial cells 4 to 5 hrs and 20 to 24 hrs were 42.9% and 38.5%, respectively. 3. The survival rate of bisected porcine embryos co-cultured in 10% FCS＋TCM-199 media containing cumulus cells 4 to 5 hrs and 20 to 24 hrs were 40.0% and 35.7%, respectively.
