Materials and methods the mouse, golden hamster and human sperm were incubated with endotoxin in different concentration for different time to get capacitation, respectively, and ar was induced by progesterone after capacitation, then the rates of capacitation and ar were detected by chlortetracycline ( ctc ) and hoechst 33258 fluorescent staining method. the medium was with endotoxin in different concentration in sperm - oocyte fusion step during ivf, then the fertilization rate was observed. the 1 - cell, 2 - cell and zona - free 2 - cell mouse embryos were incubated in the medium with endotoxin, then the rate of blastocysts was recorded

珠被並不是將珠心完全封閉,而是留有珠孔以便受精時花粉管進入胚囊,或裸子植物的藏卵器。Background : in - vitro maturation ( ivm ) of human oocytes would be an attractive alternative to gonadotrophin stimulation for in - vitro fertilization ( ivf ). it could avoid the complications of gonadotrophin stimulation and reduce the cost of drugs. however, the efficiency of existing ivm technique is suboptimal because embryos resulting from ivm oocytes exhibit frequent cleavage blocks and low implantation rate
研究背景:近20年來,輔助生育技術有了突飛猛進的發展,體外受精、卵漿內單精子注射技術( intracytoplasmicsperminjection , icsl )和種植前遺傳學診斷技術的成熟標志著人類生殖醫學進入了嶄新的領域,但同時也不能否認,在這一領域中還存在諸如妊娠率低、藥物副作用和多胎率高等問題。The female seahorse inserts her eggs into the belly of the male seahorse, and he then inseminates the eggs inside his belly
雌性的海馬將卵子輸入雄海馬的腹部,雄海馬在腹部使卵子受精。Male reproductive cells travel down the tube and join with the ovule, fertilizing it
雄性生殖細胞到達花柱然後加入卵子,使它授精。Different amount of copies in different tissues attribute to the different density of positive signals. the result of the experiment suggested that the transgenic animals can be produced by spermatozoa - mediated gene transfer after the entrapment of liposome. and because the exogenous dna occurs losing the segments. partly integration, or existin g outside of genome dna, the rate of chimerism is relatively high
結果表明: ( 1 )脂質體包裹外源基因轉染精子的方法,可將外源基因導入受精卵中,能夠獲得轉基因動物,並得到了較高的轉基因陽性率; ( 2 )精子攜帶的外源dna的整合過程是隨機的,在受精過程和胚胎早期分化過程中可能發生了片段丟失、不完全整合或游離于基因組存在而產生嵌合體。Ip3 is one of the key factors for ca2 + to release from calcium - storage and for oocytes to be activated. in this experiment, ip3 was guided into cytoplasm by instant holds on cell membrane which were made by electric stimulation, calcium - storage in cytoplasm was opened up with ip3s second messenger, and the effects of ip3 on artificial activation of oocytes was evaluated, with ca2 + waves of zygote being imitated
本實驗利用電激活過程中卵母細胞膜上形成的瞬間孔洞,向卵子內導入一定量的ip _ 3 ,通過ip _ 3第二信使途徑,打開胞內鈣庫,模仿自然受精過程中卵母細胞內ca ~ ( 2 + )的波動性變化,研究電場導入ip _ 3對小鼠卵子的激活作用。In practice this means that sperm and egg are brought together in a petri dish ; the resulting embryos are grown in a laboratory and then transferred to the womb of the mother
它實際上是把精子和卵子一起放入一個有蓋的培養皿中,並在實驗室培養由此產生的晶胚,然後將其移入母體的子宮。About 2s after fertilization in 17, sperms arrive at micropylar tube ; 3s, sperm penetrates into ovum where cytoplasm is sunken ; 5s, the spermaster come into being ; 20s, fertilization stopper appears ; 60s, sperms in micropylar apparatus begin to disaggregate
精子在受精2s到達精孔管, 3s進入卵子, 5s形成精子星光, 20s形成受精塞, 60s后精孔器內精子開始溶解。有多精入卵現象,極少數卵子多精受精。Once harested, the eggs are fertilised in the lab while the woman receies hormone drugs to ready her womb for implantation. it is then hoped a normal pregnancy will ensue
一旦採集到卵子,就將其在實驗室進行受精,同時婦女要服用激素類藥物,以便使她們的子宮適宜植入。接著就是希望正常懷孕的到來了。We also sought to determine whether we could induce human eggs to divide into early embryos without being fertilized by a sperm or being enucleated and injected with a donor cell
我們也想知道,卵子是否可以無需精子的受精作用,或不必去核再注入其他細胞核,就可以直接分裂成早期胚胎。The results showed that pcr applify a 485 specific molecular band in 672 individuals, the rate of positive reaction is 60 %, southern blot result shows a strong signal in transgenic fish. it is concluded that hu - - ifn gene has been integrated and expression. it is also that foreign gene integrating position and copy number is different individuals, by elis a detecting, 23. 5 % transgenic fish " were detected hu - - ifn gene expression in all 672 transgenic fish, but expression level of hu - - dfn is significant difference in different individuals and growth period
2000年共顯微注射32197粒草魚受精卵,出苗12945尾草魚魚苗,經孵化培育最後獲得1120尾五寸左右草魚,對1120尾草魚提取血液總dna進行pcr和southern雜交檢測, 2000年轉導的草魚的pcr檢測結果,有672尾草魚即600k轉化個體的總dna能擴增出一條485kb的特異分子帶,說明轉化個體整合有huj ifn基因,經southern雜交進一步證實,轉入的抗病相關基因己在轉基因草魚體內染色體上得以整合,但整合位點沒有固定區域,整合的拷貝數存在較大差異。分享友人
