    The effect of sperm-motility enhancing agents on the in vitro fertilization of Bubalus bubalis oocytes and their subsequent development to blastocyst

    • 摘要: 主要探讨精子活动促进剂对水牛Bubalusbubalis卵母细胞体外受精及随后胚胎发育的影响.来自屠宰场水牛卵巢的卵母细胞和卵丘细胞复合体,在体积分数为5%CO2的培养箱中培养24~26 h,然后通过体外受精测定其受精和胚胎发育能力.试验1解冻的精子用50 g/mL的胰蛋白酶处理30 min,然后进行受精;试验2受精在含不同浓度咖啡因(0, 2.5, 5.0 和 10.0 mmol/L)的受精液中进行;试验3在含不同浓度的钙离子载体A23187(0, 0.1, 1.0 和 2.5 μmol/L)的受精液中进行体外受精;试验4在PHE、咖啡因和A23187不同组合(空白,PHE, PHE+2.5 mmol/L咖啡因+2.5 μmol/L A23187和PHE+2.5 μmol/L A23187)的受精液中进行体外受精. 试验结果表明,精子用胰蛋白酶处理后的受精卵囊胚发育率显著下降(12.5%和2.6%,P<0.05),而用咖啡因和钙离子载体A23187处理,对卵母细胞的卵裂率和囊胚发育率没有明显影响.在体外受精中PHE和钙离子载体的组合使用能提高受精卵的胚胎发育率,而高浓度的咖啡因则降低卵母细胞的卵裂率和胚胎发育率.
