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.

These observations show that reprogramming is easier in interspecific embryos reconstructed with ES cells than that reconstructed with somatic cells, and that ES cells have the higher ability to direct the reconstructed embryo development normally than fibroblast cells. Oocytes were reconstructed with outbreeding Kunming albino mouse ES cells and enucleated rabbit oocytes, and the effects of the passages of ES cells and 6-DMAP on the development of interspecific reconstructed oocytes were analyzed. The interspecific reconstructed ES-rabbit oocytes were activated either by combined two set electric pulses and 6-DMAP or by two set electr

Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4. The oviducts were obtained after being delayed 5min 24h after the mice were injected with hCG. The oocytes were cultured in CZB. About 81.1% occurred spontaneous activation, evidently lower than parthenogenetic rate (96.4%) with SrCl_2. Spontaneous activable oocytes had high cleavage rate(93.2%) and 4-cell rate(87.3%). However, spontaneous activable oocytes had blastula development rate(18.7%) as low as parthenogenetic oocytes by SrCl_2(22.9%).

Our study includes four aspects. In the first aspect we study several important conditions of porcine oocytes maturation in vitro and oocytes cleavage after parthenogenetic activation and found mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15% PFF+0.57mMcysteine is a good culture condition .When the Cocs are cultured in it ,the maturation rate and oocytes cleavage rate are higher than those of foreign covered. Our result are (86.7±3.35)% and (86.3±4.16)% and the highest report of foreign is(85.7±4.1)%.In the second aspect we study the effect of different chemical activations on development of porcine parthennogenetic embryo and found two best activation method. The first one is that putting the maturation MII oocytes in the 20μmol/L ionomycin for 30 minutes and then putting them in the NCSU-23 condition containing 5μg/mICB and 5mM/L6-DMAP for 3.5 hours, the oocytes cleavage rate and morulae/blastocysts development rate are (76.7±7.6)% and (37.1±6.4)%.The second one is that putting the maturation MII oocytes in the 200μM/L Thimerosal for 20 minutes and then putting them in the NCSU-23 condition containing 8mM DTT for 30 minutes

本研究分为4个部分，第一部分对影响猪卵母细胞体外成熟和孤雌激活后胚胎分裂的几个重要条件进行了比较研究，确立了一种较好的培养方法：与颗粒细胞共培养，找到了一种适合猪卵母细胞体外成熟的培养基：mNCSU-23+15IU/mlPMSG+20IU/mlHCG+15%PFF+0.57mM半胱氨酸，成熟率和分裂率分别为(86.7±3.35)%和(86.3±4.16)%，国外报道的最高成熟率为(85.7±4.1)%；第二部分对猪卵母细胞孤雌激活的化学方法进行了研究，确立了化学激活猪卵母细胞的两种最佳方法：1将成熟的去卵丘颗粒细胞的MII期卵母细胞用20μmol/Lionomycin作用30min，再将卵母细胞培养于含5μg/mlCB和5mM/L 6-DMAP(6-二甲基氨基嘌呤)的NCSU-23培养液中，卵裂率和桑囊胚发育率达到(76.7±7.6)%和(37.1±6.4)%2将成熟的去卵丘颗粒细胞的MII期卵母细胞在200μM/L的Thimerosal中处理20min，再与8mM的DTT共孵育30min，卵裂率和桑/囊胚形成率为(81.0±2.8)%和(39.6±2.7)%；第三部分对孤雌激活胚胎的培养条件进行了研究，确立了一种最佳的胚胎培养条件：在SOF简单培养基中添加颗粒细胞进行前3天的培养，然后转入添加胎牛血清的NCSU—23培养基并和输卵管上皮细胞进行后期的培养，其桑椹胚和囊胚的发育率为(59.5±3.2)%；第四部分研究了IGF-I

Following chemical activation, blastocysts rate of the treated oocytes was similar to untreated oocytes.8 Following fertilization, however, few oocytes inhibited with CHX developed into morulae/blastocysts, due to a high incidence of polyspermy.9 Cortical granule migration occurred during inhibition, but CHX inhibition impaired CG migration, significantly no oocytes inhibited by CHX completed CG migration after maturation.10 CHX inhibition had no effects onα-microtubles and microfilaments of goat oocytes.

抑制24h转为正常培养24h，不影响卵母细胞的成熟和孤雌激活能力，并且CHX抑制后再成熟的卵母细胞经孤雌激活发育到囊胚的比例与对照组卵母细胞相似。8、体外受精后，CHX抑制后再成熟卵母细胞的多精受精现象显著增加，发育到桑椹胚/囊胚的比例显著低于对照组。9、CHX抑制过程中皮质颗粒仍能发生迁移，但是CHX抑制会对皮质颗粒的迁移造成不可恢复的损伤，使再成熟的卵母细胞内皮质颗粒不能完全迁移。10、CHX抑制对山羊卵母细胞α-微管和微丝都没有影响，无论是抑制后处于生发泡期的卵母细胞，还是抑制后再成熟的卵母细胞，微管和微丝的分布都与对照卵母细胞相似。
