Development of a New Improvement and Multiplication System in Domestic Animals Using a Embryonic Manipulation Technique II. Effects of Duration and Concentraton of Cytochalasin D on Parthenogenetic Activation and Development of Bovine Follicular Oocyte
세포조작 기술을 이용한 새로운 축산개량증식 체계 개발 II. Cytochalasin D의 처리시간과 농도가 소 난포란의 단위발생의 활성화와 발달에 미치는 효과
Abstract
Bovine follicular oocytes were matured in vitro for 3D hr and exposed to Dulbecco's phosphate buffered saline containing 7% ethanol for 7 minutes for their activation, and incubated in TCM199 containing 10% fetal calf serum (FCS) and cytochalasin D (CD). When the oocytes were exposed to cytochalasin D for 0, 5, 10 and 15 hr, 5 hr showed highest developmental rate to blastocyst (16%), expanded blastocyst (13%) and hatched blastocyst (7%). Also when the oocytes were cultured for 7 hours in medium contai ning 0, 2.5, 5 and 7.5
본 연구는 체외성숙한 소의 난포란을 ethanol로 활성화시켰을 때 cytochalasin에 노출한 시간과 농도가 난포란의 배반포단계로의 발달에 미치는 영향을 검토하였다. 30시간 체외성숙시킨 소 난포란을 7% ethanol이 든 Dulbecco's phosphate buffered saline에 7분간 노출시켜 활성화를 시킨 후, cytochalasin D가 첨가된 TCM+199+10% fetal calf serum에서 일정시간 배양하여 세포주기를 억제시켰다. 난포란을 활성화시킨 후, 0, 5, 10 그리고 15시간 cytochalasin D(5
