한국어 초록
본 연구는 체외성숙/체외수정 유래의 돼지 난자를 이용하여 체외발달시 배양액의 종류나 교체에 따른 영향을 구명하고자 수행하였다. mNCSU-23에서 체외성숙시킨 다음 mTBM에서 체외수정시킨 난자를 목적에 따라 두 가지로 나누어 실험한 결과는 다음과 같다. 1. 체외성숙/체외수정란을 NCSU-23에서 배양액 교체없이 7일 동안 배양하거나 CZB에서 4일 배양한 다음 Pig-MEM으로 옮겨서 나머지 3일간 배양한 결과, 난분할율은 배양액간 차이를 보이지 않
영어 초록
This study was carried out to examine the effects of development media and those change on in vitro development (IVD) of porcine oocytes matured and fertilized in vitro. Putative embryos, which were matured in vitro in modified NCSU-23 (mNCSU-23) supplemented with 10% porcine follicular fluid (pFF) and were fertilized in mTBM, were developed in vitro as the experimental scheme. The results are as follows. When porcine putative embryos were cultured in vitro in NCSU-23 or CZB/Pig-MEM, the percentage of oocytes cleaved was not different between two systems, but the percentage of blastocysts in NCSU-23 was significantly higher than in CZB/Pig-MEM (P<0.05). And when porcine putative embryos were cultured in vitro in NCSU-23 during 7 days with or without changing media at day 5, which was supplement with or without 10% fetal bovine serum(FBS), the percentage of oocytes cleaved, blastocysts at day 6, and the cell number of ICM, TE and total of blastocysts at day 7 were not different among three treatments. As a result of this study, it is supposed that NCSU-23 be more favorable, to develop porcine embryos derived from IVM/IVF, than CZB/Pig-MEM, but that demonstration on the effects of changing medium with fresh one stand in need of the more experiments.
