  1. 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率要顯著低於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，有助於抑制卵母細胞成熟，但在小鼠上ceo和do的自發成熟差異不明顯。
