大肠内某些内分泌细胞的发生和分布 Baffa等对9例9～24周龄胎儿大肠的五段(阑尾、盲肠、升结肠、降结肠和直乙状结肠)进行了研究,提出大肠粘膜内有大量的亲银细胞(Argentaffill)、高血糖素一样(GLI)细胞、生长抑素(SRIF)细胞、胰多肽(PP)细胞和P物质(SP)免疫反应细胞。上述细胞早在妊娠第9～10周就沿大肠粘膜散布,唯独P物质细胞是在第14～17周龄中方始散在发生和 Occurrence and distribution of certain endocrine cells in the large intestine Baffa and so on 9 cases of 9 to 24 weeks of fetal large intestine five segments (appendix, cecum, ascending colon, descending colon and straight sigmoid colon) were studied, suggesting that a large number of large intestine mucosa Argentaffill, glucagon-like (GLI) cells, somatostatin (SRIF) cells, pancreatic polypeptide (PP) cells and substance P (SP) immunoreactive cells. The cells were distributed along the large intestine mucosa as early as the 9th to 10th weeks of gestation, except that the substance P cells were scattered in the 14th to 17th weeks of age
