胎體中胚層
英文
foetal mesoderm-
Chordates are bilaterally symmetrical, triploblastic, segmented coelomates which demonstrate a deuterostomic pattern of early embryonic development
脊索動物兩側對稱、三胚層，分節的體腔，在胚胎發育的早期過程中，顯示為后口類型。It " s shown from the results that the pituitary gland of silurus asotus originates from two embryonic cells of different position ; and the doral wall of the original cavum oris forms the rostral pars distali ( rpd ) and the proximal pars distalis ( ppd ) ; the infundibulum of the ventral part of diencephalons forms the the pars intermedia ( pi ) and the neurohypophsis
結果表明：鯰腦垂體由兩個不同部位的胚胎細胞形成，原始口腔背壁外胚層分離出來的細胞構成腺垂體的前外側部（ rpd ）和中外側部（ ppd ） ，從間腦腹面漏斗體分離出來的細胞構成腺垂體中間部（ pi ）及神經垂體（ nh ） 。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。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。Notch proteins are a family of evolutionarily conserved transmembrane receptors which are involved in cell fate determination of many cell lineages. notch ligand delta is also transmembrane protein with characteristic cysteine - rich n - terminal domain responsible for notch binding
Notch基因廣泛表達于胚胎發育過程中的各種組織和各種成熟組織中具有增殖能力的細胞層，該基因編碼一個由2753個氨基酸殘基的型跨膜蛋白分子受體，其配體也是細胞膜蛋白，稱為delta 。It acts as a mediator molecule for adhesion between the surface of blastocyst and epithelial cell, and maybe involved in implantation regulation, mmp - 9 is highly expressed and secreted by trophoblast cells, and the antibody of mmp - 9 can inhibit the invasion of the trophoblast this indicates mmp - 9 is very important to the invasive embryo
Mmp - 9 （基質金屬蛋白酶- 9 ）在植入過程中滋養層細胞大量分泌和表達，而多克隆抗mmp - 9抗體可以阻斷這些滋養層細胞對基質的浸潤，這說明， mmp - 9對于胚胎的侵入至關重要。We also stained the embryos with anti - arp3 antibody and found that these two kinds of antigen are generally co - localized but arp3 were not detected in cleavage stage embryos. it was deduced that cortactin functions in the cytokinesis independent of arp3. and microinjection of anti - cortactin antibodies into the i cell stage embryos leaded to fatal developmental defects because of the unequal cytokinesis
在利用抗ap3的抗體進行的胚胎整裝染色中，激光掃描共聚焦顯微鏡觀察發現， arp3在卵裂期沒有表達， mbt后，在細胞皮層區檢測到arp3蛋白的陽性染色，在隨后的發育過程中arp3與皮層蛋白共分佈。At present, specialized courses offered in secondary health vocational schools have been tending towards comprehensiveness and appear to be more wide spread and more practical. that is more useful to the medical students facing basic levels. for example : anatomy, physiology, histological and embryology has been merged into normal humanbody
目前中等衛生學校專業課程設置已越來越趨于綜合性，出現「寬」的特徵，體現出對于面向基層第一線工作的醫學生更具有實用性，如原有的《解剖學》 、 《生理學》 、 《組織胚胎學》等學科合併為《正常人體學》 。分享友人
