摘 要:目的利用亮甲酚蓝(BCB)染色提高猪体外胚胎培养体系的效率。方法对猪卵丘卵母细胞复合体(COCs)进行BCB染色,观察染色后猪卵母细胞成熟率和早期胚胎发育能力并进行分析。结果着色组(BCB+)猪卵母细胞达到减数分裂Ⅱ(MⅡ)期的比率(91.6%)显著高于未着色组(BCB-)(64.0%)和对照组猪卵母细胞(77.5%)(P〈0.05);BCB+孤雌猪胚胎的囊胚率(34.9%)显著高于BCB-(9.5%)和对照组(23.1%)(P〈0.05);BCB+核移植猪胚胎的囊胚率(23.0%)显著高于BCB-(5.0%)和对照组(14.1%)(P〈0.05)。结论BCB染色是一种有效筛选具有较强发育能力猪卵母细胞的方法。Objective To enhance efficiency of in vitro embryos culture system of pig using brilliant cresyl blue (BCB) stain. Methods To stain the cumulus-oocyte complexes through BCB then evaluate oocytes maturation rates and developmental competence of early embryos. Results The percentage (91.6%) of the MⅡ stage oocytes of pigs was higher in the BCB-colorable group (BCB+) than those (64.0%) in the non-colorable (BCB-) and control (77.5%) groups (P〈0.05). The pig parthenogenetic blastocyst rate (34.9%) was significantly higher in the BCB+ group than those in the control and BCB-groups,(23% and 9.5%) respectively (P〈0.05). The rate (23.9%) of pig somatic cell nucleus-transferred embryos into blastocyst was significantly higher in the BCB+ group than those in the control and the BCB-groups,(14.1% and 5.0%) respectively (P〈0.05). Conclusion The BCB staining is a useful way to select more developmentally competent pig oocytes for embryo production in vitro.
