Rat cumulus - enclosed oocyte ( ceo ) and denuded oocyte ( do ) both spontaneously resume meiotic maturation in vitro , when cultured for 2h , the germinal vesical breakdown percentage of do reaches up to 88 % , and ceos get 53 % . oocytes begin to extrude first polar body 1 ( fb1 ) when cultured for 8h . mouse oocyte spontaneous maturation in vitro can be inhibited by 4mm hypoxanthine ( hx ) or 25um 3 - isobutyl - methylxanthine ( ibmx ) . while , 4mm hx can not inhibit the spontaneous maturation of rat oocyte , and the lowest effective concentration of ibmx to inhibit rat oocyle spontaneous maturation in vitro is 50um . treated with the same concentration of ibmx , gvbd percentage of rat ceo is lower than that of do , the results indicat that cumulus cells delay rat oocyte spontaneous maturation and potentate the inhibition effect of ibmx , but it ' s not the case on mouse Ceo和do培養8h時都開始排出pb1 ；在卵母細胞成熟抑制模型中， 4mm次黃嘌呤( hx )和25 m的異丁基甲基黃嘌呤( ibmx )是小鼠卵母細胞成熟的有效抑制劑，但4mm的hx抑制大鼠卵母細胞成熟效果不理想，用hx - m199和hx - mem培養24h ， gvbd率分別為61 ， 81 ，而ibmx有效抑制大鼠卵母細胞自發成熟的最小濃度為50 m ， ibmx可以降低大鼠ceo和do的gvbd率，但ceo中的卵母細胞gvbd率要顯著低于do的gvbd率， 100 m的jbmx處理24h后，大鼠ceo和do的gvbd率分別為24 ， 84 ，提示卵丘細胞的存在可以延遲大鼠卵母細胞的自發成熟，有助于抑制卵母細胞成熟，但在小鼠上ceo和do的自發成熟差異不明顯。 |

Abstract : the early embryo developmental block is a common phenomenon in mammal when embryos are cultured in vitro . many studies of phosphorus , glucose , hypoxanthine and cytoplasmic factors on early embryo developmental block carried out by different methods such as morphology , biochemistry , molecular biology and micromanipulation have been reviewed . the merit and shortcoming were analyzed and the necessity of using simple or components limited media overcoming early embryo developmental block were also reviewed . media that have been shown effective in overcoming early embryo developmental block in mouse , rat , hamster , rabbit , pig , sheep , cattle and monkey were listed 摘要哺乳動物胚胎在體外培養中普遍存在早期發育阻滯的現象.對此,人們用形態學、生物化學、分子生物學、顯微操作等手段開展了磷酸、葡萄糖、次黃嘌呤和細胞質因素對早期胚胎發育阻滯的影響的研究.本文綜合分析了共培養系統的優缺點.說明了采用完全成分已知的培養液對進行有關研究的必要性.列出了有效運用于克服小鼠、大鼠、倉鼠、兔、豬、羊、牛、猴等動物早期胚胎阻滯的成分已知的培養液的名稱。 |
