用凝集素亲和细胞化学ＡＢＣ法研究了７４例７～３８周人胚胎肠道粘膜上皮糖复合物的出现和分布。发现ＵＥＡ－１能标记１５～３８周小肠粘膜上皮的柱状细胞核上胞质和３２～３８周直肠粘膜上皮的糖萼和柱状细胞核上胞质；ＷＧＡ能标记１０～３８周小肠粘膜上皮的糖萼和柱状细胞核上胞质；ＣｏｎＡ能标记７～３８周小肠、１２～２２周升结肠、横结肠和直肠粘膜上皮的糖萼和杯状细胞核上胞质。肠粘膜上皮糖复合物的出现和分布与上皮细胞的分化有关。
The appearance and distribution of intestinal mucosal epithelial glycoconjugates in 74 cases of human embryos from 7 to 38 weeks were studied by lectin affinity cell chemistry ABC method. UEA-1 was found to be able to label the cytoplasm of the columnar nuclei of the small intestine mucosal epithelium and the glycocalyx of the rectal epithelium and the cytoplasm of the columnar nuclei of the rectum mucosal epithelium from week 32 to week 38; WGA was able to label the glycocalyx of small intestinal mucosal epithelium from 10 to 38 weeks And cytoplasm of columnar nucleus; ConA can mark 7 to 38 weeks of small intestine, 12 to 22 weeks ascending colon, transverse colon and rectal mucosa epithelial glycocalyx and goblet cell nucleus. The occurrence and distribution of intestinal mucosal epithelial glycoconjugates are related to the differentiation of epithelial cells.
