這些微化石的大小為100 ~ 200微米,相當于幾根頭發的寬度, ?們看起來出奇復雜,而且簡直就像兩側對稱動物的教科書般,展示了各種特徵:包括三個主要的組織層(內胚層、中胚層及外胚層,都是中學生物課本中熟悉的名詞) ,前後連介面部與肛門的腸腔,腸腔外還圍繞著成對的體腔。Part 1 : the culture and identification of es - d3 cells and the study of the efficiency of eb formation from es cells when grown on mef feeder layer in es culture medium or cultured in es culture medium supplemented with lif 1000u / ml, es - d3 cells being used in our experiments formed normal clones, expressed akp and kept their normal karyotype over many passages. the in vitro and in vivo differentiation experiments showed that es - d3 cells could differentiate into variety of cell types derived from three primary germ layers
結果顯示: eso3細胞在小鼠胚胎成纖維細胞上和或含白血病抑制因於億f )的es細胞培養液中形成典型的胚胎幹細胞克隆,堿性磷酸酶染色結果為強陽性,具有正常二倍體核型以及具有在體內外分化為三個胚層來源的組織細胞的潛能,而且具有形成種系嵌合動物的能力。The percentage of blastocysts in ml 6 medium with both taurine and edta ( 73. 6 + 2. 4 % ) was significantly higher than that in m16 with edta and taurine alone ( 60 + 1. 0 % and 61. 9 + 2. 0 %, respectively ). the change pattern in the cell parameters ( inner cell mass, icm ; total cell numb, tcn ) of the three groups was the same as the blastocyst formation rate
且m16 + tau + edta培養液中的囊胚總細胞數、內細胞團數、內細胞團與滋養層細胞數的比率均顯著高於m16 + tau和m16 + edta培養液的( p 0 . 05 ) ;內細胞團占總細胞數的百分率也相應增加。Human bone morphogenetic protein 3 is a member of tgf - b superfamily. lt can induce the differentiation of cartilage and bone tissue in mesenchymal cell. and is important to bone self - repairment and bone development during embryo morphogenesis. in addition, some other biological activities of hbmp - 3 have also been found. such as inducing development of embryo and stimulating differentiation of neural and blood cells. therefore, there is a great prospect in the use of hbmp - 3. there is trace content of hbmp - 3 in human body. it has been expressed in the expression system of eukaryotes and prokaryotes respectively, but its application is restricted because of defects in the process and modification after translation in prokaryotic cells and higher costs and lower yields existed in eukaryotic expression system
人骨形成蛋白3 ( hbmp - 3 )屬于tgf -超家族的一員,可以誘導間充質細胞分化為軟骨和骨,在胚胎時期骨骼發育和骨再生修復中起著重要的作用,而且對胚胎發育過程中中胚層的誘導和分化、造血組織的發育以及神經系統的發育和修復等都起著重要作用,因而hbmp - 3有廣闊的市場前景。它在人體內含量極微,盡管研究人員已經在原核細胞和真核細胞表達系統中分別進行了表達,但是由於原核表達系統缺乏翻譯后的加工修飾,真核表達系統存在成本高、產量低等特點,限制了其在臨床上的應用。Pre - clinical studies showed that needleless injected fluids follow the path of least resistance and does not pass into the substance of bone, media of blood vessels or into the fibre substance of the nerve trunks
臨床研究顯示,無針美槊療法所注入的液體不會滲入骨頭、血管或神經內,它會沿著最少抗體的路徑進入肌膚組織,並且加速皮膚細胞的新陳代謝,讓雞尾酒中胚層綜合物質更容易於肌膚所吸收。It contained 187 amino acids deduced from the nucleotide sequence, and showed 65 % amino acid sequence identity with human aoeb166. the analysis of n - and c - terminal domains revealed amino acid sequences characteristic of features of mitochondrial and peroxisomal targetin
原位雜交分析表明從受精卵到神經胚, aophihmgb基因廣泛表達,但隨著發育的進行,中胚層、內胚層和神經管的表達減弱,到1天幼蟲期,僅在表皮可檢測到表達。The ratio of ( s + g2 ) / ( g2 + m + s ) and pi value of mc - 3t3 - el cells increased in the condition of 1um / l e2. the effects of e2 on igfbp - 6 and igf - 2 gene expressions were suppressed by tcdd and ra. the binding of ere at higfbp - 6 5 " - utr ( dna sequence : aactctgacc, + 94 to + 103 ) was enhanced by tcdd
第三部分igfbp一6基因5 』一utr中ere的鑒定及功能分析目的:骨骼組織起源於胚胎期中胚層,維持正常的胚胎期骨骼發育需要多種生長因子、細胞因子和激素的參與,其中雌激素可通過多種途徑作用子中胚層內間Although the cell parameters ( icm and tcn ) of blastocysts of both groups differed significantly ( p < 0. 05 ), the mml 6 + e2 + p group was the closest to the in vivo group, and those of the mm16 group were the lowest
同時添加e2和p的mm16培養液中囊胚的細胞總數、內細胞團數、內細胞團占總細胞的百分率和內細胞團與滋養層細胞數的比率低於體內正常發育囊胚,但顯著高於其它體外培養組( p 0 . 05 ) 。分享友人
