Results The Southern blot result showed that 4 among 188 goats produced by pronuclear microinjection had integrated hEPO gene.

结果在原核注射获得的188头羔羊中，经Southern blot法检测有4头羊含有hEPO基因，其中3头为母羊，1头公羊于出生后20d死亡；3头转基因母羊hEPO基因的拷贝数分别为1、10、2；Western blot检测结果显示转基因羊乳中的hEPO分子质量为32kDa；MTT法检测结果表明，在泌乳10d的3只转基因羊乳汁中，每毫升乳汁中hEPO活性分别达到1.17×102IU、1.90×104IU、1.91×104IU。

Among these significant advances has been the ability to alter the genetic constitution of eggs by pronuclear and nuclear transfer as well as by the introduction of specific cloned genes into eggs and embryos.

The present study was conducted to investigate the effect of 6-DMAP on parthenogenetic activation rate, pronuclear formation and in vitro parthenote development of in vitro matured goat oocytes.

体外成熟的山羊卵泡卵母细胞用7%的乙醇和5μmol/L的离子霉素刺激处理后，分别置于含2 mmol/L 6-二甲基氨基嘌呤(6-DMAP)和不含6-DMAP的培养液中培养4 h，研究6-DMAP对体外成熟山羊卵泡卵母细胞孤雌激活率、原核形成以及孤雌胚体外发育潜能的影响。

The extra pronuclear of triploid zygotes after IVF is from sperm and the zygotes have no implantation value.

IVF后3PN卵子中多余的原核多为精子来源，没有移植价值；ICSI后3PN中多余的原核非精子来源，ICSI后3PN中二倍体率与IVF相比显著增高，在患者ICSI后无2PN卵子时可考虑行植入前遗传学诊断。

Even though the older oocytes were easier to activate and developoed more rapidly to the pronuclear stage than younger ones after artificial stimulation, the percentage of blastocyst development was lower than that in younger oocytes.
