摘要: 体外成熟的绵羊卵母细胞,经5 μmol/L A23187 5 min和2 mmol/L 6-DMAP 4 h激活后,分别在SOFaa、M-199两种培养液中进行培养,试验比较了SOFaa、M-199液分别添加BSA和不同浓度(10%、20%)胎牛血清对绵羊孤雌生殖胚体外发育的影响。M-199+FCS组的卵裂率显著低于SOFaa+BSA和SOFaa+FCS组(P<0.05),SOFaa+BSA组的囊胚率显著低于M-199+BSA、SOFaa+FCS、M-199+FCS三组(P<0.05);SOFaa+10% FCS与SOFaa+20% FCS组的卵裂率及囊胚率均无显著差异,M-199+10% FCS和M-199+20% FCS组的卵裂率及囊胚率间均无显著差异。结果表明:SOFaa比M-199更适合绵羊孤雌生殖胚体外发育,此外添加10%的FCS即可达到较好的培养效果。

Abstract: Matured ovine oocytes were activated by 5 μmol/L A23187 for 5 min an
d then 2 mmol/L 6-DMAP for 4 h,afterwards cultured in SOFaa and M-199 medium supplemented with BSA and serum of different concentrations, respectively. The cleavage rate of group M-199+FCS(29.9%) was significantly lower than SOFaa+BSA(52.7%) and SOFaa+FCS (52.8%) groups (P<0.05). And the blastocystrate of SOFaa+BSA(0.8%) group was significantily lower than M-199+BSA(7.6%),SOFaa+FCS(11.8%),M-199+FCS(10.2%) groups (P<0.05). The cleavage rate and blastocyst rate of oocyte treated with SOFaa+10% FCS(50.7%,11.3%)and SOFaa+20% FCS(59.2%,9.9%)were not significantly different, and those data of M-199+10% FCS(29.6%,5.6%) and M-199+20% FCS(32.4%,9.9%)were also same. These results showed that SOFaa medium is suitable for the development of ovine parthenogenetic embryos cultured in vitro , and SOFaa added with10% FCS can improve its function on those IVC embryos.
