摘  要：
探讨乙二胺四乙酸钠(EDTA-Na)对猪卵母细胞的体外成熟和孤雌激活后早期发育的影响。利用屠宰场猪卵巢卵母细胞,在不添加或添加不同浓度EDTA-Na的成熟培养液中体外成熟44~48 h,挑选核成熟卵母细胞进行孤雌激活,然后移到不添加或添加不同浓度EDTA-Na的胚胎培养液中进行体外培养168 h。结果表明:(1)胚胎培养液中添加适当浓度(25~100μmol.L-1)EDTA-Na对体外成熟猪卵母细胞孤雌激活后的早期发育具有促进作用,在EDTA-Na浓度为100μmol.L-1时,效果最佳;(2)成熟液和胚胎培养液中同时添加100μmol.L-1EDTA-Na对体外成熟猪卵母细胞孤雌激活后的早期发育具有促进作用;(3)成熟液或/和胚胎培养液中添加不同浓度EDTA-Na对体外成熟培养后的猪核成熟卵母细胞及孤雌激活后的4-细胞孤雌胚SDS-PAGE电泳的蛋白质表达图谱都无显著影响。

摘  要：
This study was to investigate the effect of EDTA-Na on in vitro maturation of porcine oocytes and subsequent early development after parthenogenetically activation.Porcine oocytes from abattoir ovaries were matured in maturation medium containing different concentrations of EDTA-Na for 44～48 h.Oocytes with the first polar body were parthenogenetically activated and then cultured in NCSU-23 medium containing different concentrations of EDTA-Na.The results showed:(1) supplementation with 25～100μmol·L1 EDTA-Na in embryo culture medium is beneficial to early development of porcine parthenogenetic embryos derived from oocytes matured and artificially activated in vitro,and the effect is significant with EDTA-Na concentration is 100μmol·L-1,its effect is the best;(2) supplementation with 100μmol·L-1 EDTA-Na in maturation and embryo culture media together is benificial to early development of porcine parthenogenetic embryos derived from oocytes matured and artificially activated in vitro;(3) supplementation with different concentrations of EDTA-Na in maturation medium or/and embryo culture medium has no significant effect on protein expression profiles of SDS-PAGE electrophoresis of porcine oocytes matured in vitro and 4-cell parthenogenetic embryos after artificial activated.
