摘要:

为了进一步优化猪胞浆内单精子注射(intracytoplasmic sperm injection,ICSI)胚胎制备条件,本试验将Piezo操作系统应用于猪ICSI胚胎制备过程中,并以胚胎各阶段存活率、分裂率和囊胚率作为衡量指标,对比Piezo操作系统与传统斜口针操作、Piezo操作条件时操作液中添加CB浓度、操作台温度及精子的不同处理方法对猪ICSI胚胎发育的影响。结果表明,Piezo操作系统可以显著提高注射卵的存活率和卵裂率(P<0.05),但对囊胚率没有显著影响(P>0.05);利用Piezo进行猪ICSI时,操作液中添加CB,可以减少显微操作时注射针卵母细胞的损伤,其中以7.5 μg/mL CB效果最佳;操作台温度30℃最适合制备猪ICSI胚胎;精子预先进行超声波断尾处理对猪ICSI胚胎的早期发育无显著影响。研究结果表明,精子预先进行超声波断尾处理后,操作液中添加7.5 μg/mL CB、操作台温度30℃,应用Piezo操作系统比较适合猪ICSI胚胎制备。

Abstract:

In order to optimize the preparating conditions on pig intracytoplasmic sperm injection (ICSI) embryos,the Piezo operating system was used in this experiment and the embryonic survival rate,cleavage rate and cell numbers of blastocysts developed in various stages were measured as traditional and Piezo operating system,the concentration of CB,the operating temperature with Piezo operating system and different sperm processing method in preparating pig ICSI embryos.The results showed that Piezo operating system could significantly improve the survival rate and cleavage rate of injected oocytes (P<0.05),but there was no significant effect on blastocyst rate.There was a slight damage to oocyte added CB in the operating fluid,and adding 7.5 μg/mL CB was most concentration,30℃ was most appropriate operating temperature,but there was no significant effect of early development on pig ICSI embryos with breaking sperm tail with ultrasonic wave.The results suggested that Piezo operating system could significantly improve the survival rate.The results suggested that breaking sperm tail with ultrasonic wave,adding 7.5 μg/mL CB in operating fluid and 30℃ of operating temperature and using Piezo operating system was more suitable for preparating pig ICSI embryos.
