摘要:
为探讨直径为2 mm以下和2~6 mm猪卵泡卵母细胞的体外培养分裂率与囊胚率差异,采用相同体外成熟培养条件,来培养从不同直径的2种卵泡中所抽出的卵母细胞,在卵母细胞成熟培养后44~48 h,对卵母细胞进行化学激活和体外培养,观察胚胎体外发育能力;在培养48 h时进行分裂数据统计,培养168 h时统计囊胚个数。结果发现,2 mm 以下猪卵泡卵母细胞孤雌激活后胚胎的体外培养平均分裂率与2~6 mm猪卵泡卵母细胞孤雌激活后胚胎的体外培养平均分裂率差异显著,分别为62.46%、81.76%(P<0.05);2 mm以下猪卵泡卵母细胞孤雌激活后胚胎的体外培养平均囊胚率与2~6 mm猪卵泡卵母细胞孤雌激活后胚胎的体外培养平均囊胚率差异不显著,分别为11.71%、15.30%。说明正常卵泡、小腔卵泡的卵母细胞在体外成熟后,孤雌激活胚分裂率依次降低,孤雌胚胎的分裂能力随卵泡直径的增大而增强;正常卵泡、小腔卵泡的卵母细胞体外成熟后,孤雌激活胚囊胚率随卵泡直径的增大有一定增高,但变化不显著。
