2、胞为受体,构建异种核移植重构胚,并从核移植融合/激活方式、培养液两个方面进行优化。【结果】70枚食蟹猴一猪异种核移植胚胎中,有49枚分裂(70.o%),与猪同种核移植胚胎的分裂率(76.6%)无显著差异;使用微卫星引物D15S823对食蟹猴一猪异种核移植胚胎进行遗传学鉴定,均能扩增获得D15S823条带(350bp);食蟹猴一猪异种核移植胚胎融合后1h的染色体早熟凝集率(24.2%)显著低于猪同种核移植胚胎(44.7%)和猪孤雌激活胚胎(100.0%),通过使用无Ca2+融合液能够显著提高染色体早熟凝集率(48.2%);在PZM一3、HECM.10和HECM一1
3、0+10%FBS3种培养液中,食蟹猴一猪异种核移植胚胎的分裂率无显著差异。【结论】食蟹猴体细胞核能够在猪MII期去核卵母细胞胞质中发生核重塑,并发育到8.细胞阶段。关键词:食蟹猴;猪;异种核移植;胚胎发育中图分类号:Q813.2文献标志码:A文章编号:2095—1191(2013)09—1547—05ConstructionofclonedcynomolgusmonkeyembryosusingenucleatedpigoocytesLIANGMing—ming,QUANLi,HUANGGao-bo,SUNRu-yu,XUHui-yan,LUSheng—shen
