In addition , insulin - ir cell , chromogranin - a - ir cell , testosterone - ir cell and epithelial membrane antigen - ir cell were not detected in the digestive tract of alligator sinensis embryos . the kinds and the numbers of endocrine cells in the digestive tract and glands were less at early prenatal stages but increased greatly in the midterm of development . in the digestive tract of last prenatal stages , it was stomach that had the most endocrine cells and might play the most important role in regulating the growth and differentiation of the digestive tract , the duodenum was in the second place 縱觀揚(yáng)子鱷胚胎消化道和消化腺內(nèi)分泌細(xì)胞發(fā)生的情況,可得出如下結(jié)論: )胚胎發(fā)育早期,胰腺內(nèi)分泌細(xì)胞的數(shù)量和種類較多,可能是早期胚胎重要的內(nèi)分泌調(diào)控部位;胚胎中期消化道和消化腺內(nèi)分泌細(xì)胞的數(shù)量和種類增加最多,是內(nèi)分泌細(xì)胞分化發(fā)育的重要時(shí)期:胚胎晚期,以胰腺和幽門、十二指腸的內(nèi)分泌細(xì)胞最密集,為孵出后的消化和吸收的功能調(diào)控做好生理準(zhǔn)備。
The endocrine cells in the digestive and glands of alligator sinensis embryos aged from 8th to 55th day were localized and compared by using immunohistochemical method with thirteen kinds of antiseras of hormone . during the development of pancreas in alligator sinensis embryos , somatostatin ( ss ) immunoreactive ( ir ) cells , 5 - hydroxytryptamine ( 5 - ht ) - ir cells , glucagon ( glu ) - ir cells , epidermal growth factor ( egf ) - ir cells appeared on 18th day . no p53 protein - ir cell , gastrin - ir cell , testosterone - ir cell , chromogranin a - ir cell , vasoactive intestinal polypeptide - ir cell , epithelial membrane antigen - ir cell or insulin - ir cell was found in the pancreas of alligator sinensis embryos 本實(shí)驗(yàn)采用免疫組織化學(xué)技術(shù),應(yīng)用13種不同的抗血清,對孵育時(shí)間8 ? 55天揚(yáng)子鱷胚胎消化道及消化腺內(nèi)分泌細(xì)胞的種類進(jìn)行鑒別、定位和比較,結(jié)果如下:揚(yáng)子鱷胚胎胰腺中,生長抑素、 5 ?羥色胺、胰高血糖素、表皮生長因子、胰多肽免疫反應(yīng)陽性細(xì)胞出現(xiàn)于第8天; p物質(zhì)免疫陽性細(xì)胞出現(xiàn)于第18天; p53 、胃泌素、睪酮、嗜鉻素a 、血管活性腸肽、上皮膜骯原、胰島素免疫陽性細(xì)胞在各期揚(yáng)子鱷胚胎胰腺中均未發(fā)現(xiàn)。
epithelial membrane antigenとは意味:上皮膜抗原{じょうひ まく こうげん} epithelial membrane antigen meaning:[Medicine] Carbohydrate antigen elevated in patients with tumors of the breast,ovary,lung,and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows...
