Methods Human umbilical cord blood mononuclear cells were isolated by Ficoll density-gradient centrifugation. EGM-2 culture fluid was added, and then cells were plated on dishes coated with human fibronectin. After 48 h, the nonadherent cells were collected and replated on fibronectin-coated dishes.

A new picorna-like virus was isolated from dead Evtropis oblique larvae deceased from NPV infection. Electron microscopic observations of purified virions were non-enveloped isometric particles with diameter of 26nm. The virions contain two capsid proteins: 31.5kDa and 28.8kDa, the amount of later is 2.5 times more than that of the former. Analysis of 3′terminal sequence of EoPV clone identified that it can encode RdRp and has eight conserved motifs. Homology analysis shows that it is closely related to Perina nuda picorna-like virus.

从核型多角体病毒感染致死的茶尺蠖幼虫尸体中分离到一株微小RNA病毒透射电镜观察纯化的病毒粒子为无囊膜、无表面特征、直径约26nm的球状颗粒。16%的SDS-PAGE显示它有两个分子量为31.5 kDa和28.8 kDa的衣壳蛋白，后者的含量是前者的2.5倍。3′端克隆序列分析表明EoPV基因组3′有poly尾，编码RNA聚合酶，含有微小RNA病毒RNA聚合酶的八个保守基序，同源性分析表明它与榕透翅毒蛾微小RNA病毒亲缘关系最近。

The results showed that the rates of mature oocyte were 75.2％, 73.1％, 69.8％, 63.5％and oocyte at telophase of MI were 16.3％, 15.9％, 16.9％, 27.0％, respectively. The rates of maturation of oocytes cultured in TCM199 with serum, EGF and TGFαwere significantly higher than that of with BSA team (P＜0.05) and the number of oocyte stayed at telophase of MI in TCM199 with serum, EGF and TGFαteam were significantly less than that with BSA team(P＜0.05); Significant higher rates (66.6％, 66.6％, 73.6％) of normalα-tubulin distribution in oocytes cultured in TCM199+ serum, EGF and TGFαwere compared to that of TCM199+BSA(43.3％)(P＜0.05). The rates of oocyte with cortical granules in cortex were 58.8％, 33.9％, 54.7％and 47.9％respectively, there was significant difference between oocytes cultured with serum, EGF and BSA(P＜0.05). In conclusion, TGFαand EGF can promote the oocyte nuclear transition from telophaseⅠto metaphase of meiosisⅡ, and improved the expression and distribution ofα-tubulin during the ovine oocytes maturation; EGF and serum could promote oocyte cytoplasm maturation. The results suggested that EGF and TGFαmight substitute some substance in serum to improve the quality of oocyte nucleus maturation in vitro, but EGF might be more functional than TGFαto promote the maturation of ovine oocyte ooplasm.

三、EGF和TGFα对卵母细胞成熟的影响未成熟卵母细胞分别在TCM199基础培养液+血清、TCM199基础培养液+BSA+EGF、TCM199基础培养液+BSA+TGFα和TCM199基础培养液+BSA四组成熟培养系统中成熟培养，22小时后上述各组卵母细胞的核成熟率分别为75.2％、73.1％、69.8％、63.5％，处于第一次减数分裂末期的比率分别为16.3％、15.9％、16.9％、27.0％，在添加血清、EGF、TGFα各组中核成熟率显著高于其它各组(P＜0.05)，处于末期的比例明显低于其它各组(P＜0.05)：添加血清、EGF、TGFα各组在a-Tubulin蛋白的分布与表达上(66.6％、66.6％、73.6％)明显高于BSA组的正常率43.3％(P＜0.05)；各组CG发生迁移较好的卵母细胞的比率分别为58.8％、33.9％、54.7％、47.9％，血清组和添加EGF组CG迁移至皮质区的比例明显高于仅添加BSA处理组(P＜0.05)。
