1、摘要猪卵母细胞的体外成熟与孤雌激活研究生姓名:陈晓宇指导教师:李青旺教授张德福研究员摘要猪卵母细胞体外成熟和孤雌激活的研究,有助于完善猪卵母细胞体外成熟体系、提高成熟率和探索出适宜的孤雌激活方法。但是现有猪卵母细胞体外成熟体系成熟率较低,孤雌激活率和激活质量也较差,制约猪胚胎工程进一步研究。本试验主要对猪卵母细胞不同收集方法、不同添加物在体外成熟体系中的作用以及温度和乙醇在孤雌激活中的激活效率进行了研究,获得了如下结果。①切剖法所获A级卵母细胞比例显著高于抽吸法和机械破碎法(41.7%、27.5%,20.3%,P2、获卵母细胞的PbI排出率显著高于机械破碎法(41.6%、16.3%,P3、(42.0%、11.0%,12.7%,P0.05);添加0.6mmo1/LL-cysteine(半肤氨酸)和1011g/LrpGH(猪重组生长激素)后卵母细胞成熟率分别是30.4%和61.7%,均显著高于其它浓度(P4、者之间无显著性差异(P>O.05);血清在添加时灭活处理与否,差异并不显著(32.2%,29.4%,P>O.05).⑤100111微滴法培养卵母细胞的体外成熟率优于400111四孔板(33.7%,26.5%)(PO.05);在培养24h后去掉培养液中的激素可显著提高卵丘扩散率(100%、77.5%,P<0.05),但更换激素对PbI排出率无明显促进作用(P>0.05)o5、⑥猪卵母细胞在7%乙醇处理10min后再经过25℃下40min的孤雌激活,2-cell孤雌卵裂率为33.9%,显著高于乙醇单独激活时的3.7%(P<0.05);4-cell孤雌卵裂率是11.9%,显著高于温度单独激活时的1.6%(P<0.05)。关键词:猪卵母细胞体外成熟孤雌激活猪卵母细胞的休外成熟与孤雌激活InVitroMatureandPathenogeneticActivationofPorcineOocytesPostgraduate:ChenXiaoyuAdviser:LiQingwangScientistZhangDefu6、(TheCollegeofAnimalScienceandTechnologyNorthwestSci-techUniversityofAgricultureandForestryYangling,Shaanxi712100,F.R.China)AbstractsTheobjectiveofthispaperwastryingtoestablishanoptimummaturesystemtoimprovematureefficiency,andfindapropermethodofpathenogenticactivationofp7、orcineoocytesmaturedinvitro.Invitromature(IVM)rateandpathenogeticactivationrateofporcineoocytes,atpresent,arestilllow,whichbecomeabarriertoprogressinresearchofporcineembryonicengineering.Theefectofoocytecollectionmethods,diferentsupplementsinmaturesystemandpathenogetica8、ctivationmethodsonporcineoocytedevelopmentwereinvestigatedinthisstudy.Theresultswereasfollows:①RateofclassAcum
