  4. In summary, we constructed and characterized a bac library of silky, a unique chinese native breed of chicken. the library has high genome coverage ( 13 - fold ), chimerism ( 6 % ) and overlapped bacs, which made it a valuable resource to complete chicken physical map, study functional genes and construct bac contigs. we analyzed the whole genomic sequence and snps of tyrp1 and found that silky tyrp1 is different with other breeds both in microsatellite and transcription regulation site

    中國農業人學博卜學位論文摘要本研究構建了中國特有雞種絲羽鳥骨雞基因組bac文庫並進行了文庫質量鑒定,它所具有的13倍高基因組覆蓋率、 6 %的嵌合率和部分重疊的克隆使其成為完善雞的基因組圖譜、研究基因功能和構建bac重疊群的優質資源。
  5. 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。
  6. Hematopoietic chimerism produces durable and robust immune tolerance to kidney allografts, although incomplete tolerance to donor skin grafting

    造血嵌合能夠對腎移植產生持久有力的免疫耐受,但對于皮膚移植無效。
  7. These data showed that the chimerism were specially tolerant to donor xenoantigens in skin grafting and mixed lymphocyte reaction ( mlr ) assays, however were still immunocompetent to mhc - disparate third party c57bl / 6 mouse. in the second experiment, mice of group b appeared with variant degree of wasting, diarrhea, fur losing, and all died within 15 days. pathologic changes of liver and intestine were inflamming cells infiltrating and necrotizing

    肝、小腸切片均有明顯病理改變,主要表現為腸粘膜部分脫落、壞死和炎性細胞浸潤,肝實質內有灶性淋巴細胞及多形細胞浸潤,並可見局灶性壞死,兩者均符合gvhd病理改變。
  8. After dna analysis, six white pigs is not present chimerism in various tissues. to one skin pigment piglet, chimerism is present in skin, brain, pancreas, pituitary gland and blood, but not in heart, lung, liver, spleen, kidney, intestine and ovary. the detection of another skin - pigment chimera is similar to the analysis result of wzsp

    通過dna分析進一步得出,所產8頭仔豬,其中六頭白豬體組織未發現嵌合現象;其中一頭皮膚色素嵌合體豬的皮膚、大腦、胰、甲狀腺、血是嵌合的,而心、肺、肝、脾、腎、空腸、卵巢這些組織並沒有嵌合;另一頭皮膚色素嵌合體豬的檢測結果和五指山豬取得相似的結果。
  9. This study did microinjection to kunming white mouse inbred embryos to test its in vitro developmental ability, then pluripotency of porcine eg cells was tested with production of chimera by blastocyst injection. finally, first chimeric pig in china was delivered, and by chimera analysis, chimerism is present in some tissues

    本研究首先利用近交系昆明白小鼠進行胚胎顯微注射觀察發育效果,然後利用所獲五指山豬eg細胞製作嵌合體檢驗eg細胞多能性,最終獲得國內首例胚胎幹細胞( eg細胞)嵌合體豬,經dna分析確認在多種組織中存在嵌合狀態。
