摘要: 为进一步完善牛胚胎体外发育体系,以体外受精胚胎为研究对象,对精子获能液、胚胎培养液、血清与BSA添加浓度、卵丘细胞共培养等影响体外胚胎发育体系的各个因素进行筛选优化。结果表明,BO获能液比普通获能液能够获得更高的卵裂率;添加葡萄糖、BSA以及不同浓度血清的牛胚胎培养液比未添加组有更好的发育效果,卵裂率、囊胚率分别达到(79.85±0.74)%、(28.69±1.45)%;在此基础上,牛卵丘细胞与牛胚胎共培养可将囊胚率进一步提高至(32.70±1.73)%,并用免疫荧光染色验证其卵丘细胞未发生凋亡。本研究进一步优化了牛胚胎体外发育体系,提高了体外胚胎的囊胚发育率。

Abstract: Abstract: In order to improve the system for embryo culture in vitro. In vitro fertilization embryos were used as research models, screening and optimizing the various factors that affect IVF embryo development in vitro, such as sperm capacitation medium, embryo culture medium, the concentration of serum and BSA and cumulus cells and embryo co-culture. Our results showed that the the IVF embryos cultured in BO capacitation medium obtain higher cleavage rate than that cultured in normal capacitation medium. Added glucose and, BSA and FBS to embryo culture medium obtained better embryo development effect, the cleavage rate and blastocyst rate reached (79.85±0.74)% and (28.69±1.45)% respectively. On this basis, the blastocyst rate increased to (32.70±1.73)% in bovine cumulus cells and embryos co-culture,The results of immunofluorescence staining showed that the bovine cumulus cells was not apoptotic during co-culture. This study further optimized the bovine embryo development system in vitro and improved the rate of blastocyst in vitro culture.
