It is concluded that (1) there are no relationships between fusion rate and relativeness of the recipient cytoplasm to nucleus donor cells,(2) cytoplast of the goat MII oocyte can support the preimplantation development of SCNT embryos reconstructed with nucleus from other species,(3) the blastocyst rate of close relative inter-species SCNT embryos is higher than that of distant relative inter-species SCNT embryos.

The results showed that 1 there were no significant differences in the rates of cytoplast protrusion and enucleation between oocytes that were incubated in colchicine (0.4 μg/mL) for 0.5 h and oocytes that were incubated in colchicine (0.4 μg/mL) for 1 h, and the rate of cytoplast protusion can be 85.4% while the rate of cytoplast enucleation is 100%. 2 There was no significant difference in oocyte enucleation between oocytes treated with medium containing 0.2 μg/mL colchicine for 0.5 h and oocytes treated with medium containing 0.4 μg/mL colchicine for 0.5 h. 3 A maturation time of 18–23 h did not affect the rates of cytoplast protusion and enucleation by chemically assisted enucleation, whereas the rate of enucleation of oocytes by blind enucleation was found to decrease with a prolonged incubation time. 4 The development rates of reconstructed embryos could not be influenced by these two enucleation methods, increased from oocytes matured for 21–23 h.

结果表明： 1 卵母细胞在0.4 mg/mL的秋水仙素溶液中分别孵育0.5 h和1 h，胞质突起率和去核率没有显著的差异，突起率可高达85.4%，去核率达到100%； 2 0.2 mg/mL或0.4 mg/mL秋水仙素溶液将卵母细胞处理0.5 h，对去核效果没有显著影响； 3 对于体外成熟18~23 h的卵母细胞，随着成熟时间的延长，盲吸法的去核率降低，但没有影响秋水仙素诱导胞质突起的比率和去核率； 4 两种去核方法对重构胚的发育没有产生显著影响，但成熟21~23 h卵母细胞重构胚囊胚的发育率显著高于成熟18~20 h卵母细胞重构胚囊胚的发育率。
