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。 |

In the presence of hx , oocyte maturation to mil and the extrusion of polar body were highly synchronized , the oocytes matured to mil stage were activated in higher rates than oocytes matured without hx , and those oocytes matured exposed to hx for all the 24h showed a high rate ( 55 % ) of spontaneous activation Hx存在情況下成熟到m期的卵母細胞排出第一極體時同步化程度高，其孤雌活化能力高于正常成熟卵母細胞， hx作用24h組出現自發激活現象(自發活化比率55 ) 。 |

Microtubule form spindles during mil stage . it plays an important role in polar body extrusion , pronuclear formation and and early cleavage . as a result , it is reasonable to consider the line under - 9 - cell membrane and the spindles are both important indicators to evaluate cytoplasmic maturation 本研究分為兩部分，第一部分主要在卵巢顆粒細胞原代培養的基礎上，研究顆粒細胞的分泌功能以及fsh 、 gnrha對分泌功能的影響，其中顆粒細胞的純度鑒定、顆粒細胞分泌igfl和egf以及gnrha對顆粒細胞功能影啊的研究尚未見報道。 |

Since the success of dolly , the first cloned sheep with the adult somatic cells as karyoplast donor , new approaches have been developed for nuclear transfer technology . here we describe a handmade cloning method which combines the chemical induced enuleation and zona - free technology in embryo culture . enuleated oocytes were derived by exposing the oocytes to demecolcine and cytoheximide supplemented mdium sequently and its chromosome was depleted to the first polar body 將培養10h的化學去核卵母細胞與供體成纖維細胞融合后lh 、 2h 、 3h ，分別有77 . 6 % 、 70 . 6 % 、 58 . 9 %重構胚的染色質發生凝集，其余胚胎的染色體則處于原核期;而只在融合后3h ， 27 . 9 %重構胚被標記出組裝的紡錘體，且其中的同源染色體己經分離。 |

During male gametogenesis , the spermatogonia became primary spermatozoa through mitosis , and then became fourth equivalent cytoplasm , round sperm through meiosis . after maturation , they participated in embryo development with the mature oocyte through fertilization . but in female gametogenesis , the primary oocyte formed a matured egg and 1 ~ 3 polar bodies ( pb ) 雄性動物精子發生過程中精原細胞最后一次有絲分裂形成二倍體精母細胞后，經過兩次減數分裂形成了四個含等量細胞質、圓形的精子細胞，最終發育成四個具有正常生理功能的精子，與成熟卵母細胞受精后參與胚胎發育。 |

The objective of this study was whether the reconstituted embryo with the second polar body ( pb2 ) can develop . firstly , female mouse was superovulated with pmsg + hcg and keep in the same cage with male mouse , the pronuclear embryo was obtained at the different time after hcg injection with different motheds to investigate the existing time of pronuclear embryo . then pronuclear embryo was cultured with three different mediums to select the best to culture in vitro 母鼠在注射hcg后與公鼠同籠交配，并在注射hcg后不同時間(從18h到26h ) 、不同方法(體內法和體外法)獲取胚胎，研究獲取原核胚的最佳時間；在此基礎上獲得具有第二極體原核胚，然后對原核胚進行顯微操作，去除雌原核并注入第二極體，探討第二極體內遺傳物質支持胚胎發育的潛力；同時利用dna特異性染料h33342對原核胚進行染色，顯示并比較原核和第二極體內的dna遺傳物質。 |

The second medium included egf ing / ml and igf - 1 long / ml in addition to the control . likewise , the last medium contained 50 % granulosa cells conditioned medium . oocytes were cultured for 16 or 18 hours , and only the oocytes underwent first polar body extrusion were collected for future study Inmegflug ml十igf 110ng ml ）和顆粒細胞生長液組乃0顆粒細胞生長液） ，對昆明白小鼠生發泡期（ ge訕nalvesicle ， gv ）卵母細胞進行體外成熟培養； 5 |

These results indicate that chx at an app ropriate concentration can improve the parthenogenetic development of buffalo oocytes , cb at an appropriate concentration may inhibit the extrusion of the first polar body and increase the proportion of activated oocytes with two pronuclei 結果表明，適當濃度的chx能提高卵母細胞激活效果，適當濃度的cb可抑制卵母細胞第二極體的排出，提高孤雌激活后雙原核的比例。 2 |

After 15h of maturation . 98 % of oocytes released the first polar body and thus the first meiosis of mouse oocytes ended . secondly , strong chromosome to chromosome binding was induced by culturing pro - mi oocytes in demecolcine supplemented medium 第一次減數分裂期小鼠卵母細胞經化學去核后，去除透明帶，并胎兒成纖維細胞粘合、電融合并srcl2激活，培養于微孔中。 |

Then the zona and polar body of oocytes treated with drug were removed by transferring into the m2 containing 0 . 5 % protease . the mouse fetal fibroblast cells were glued to the oocytes memb 該結果與重構胚的體外發育相符，表明正是這些己恢復微組裝功能的化學去核卵母細胞才對其供體核具有重編程的支持能力。 |
