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 ） 。These congenital lesions arise from abnormal separation of the endoderm and neuroectoderm during embryogenesis
這些先天性的異常是因為再胚胎發育時，內胚層與神經外胚層不正常的分離所造成的。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。
