The microanatomy of the intestinal epithelium in the Chinese soft-shelled turtle (CST) was studied by light and transmission electron microscopy (TEM). The small intestinal epithelium (SIE) was single layered or pseudostratified. The enterocytes contained mitochondria or mitochondria and lipid droplets. The enterocytes were arranged tightly in the apical parts of epithelium and connected by desmosomes and interdigitations. The large intestinal epithelium (LIE) was pseudostratified and the enterocytes did not contain lipid droplets. Enterocytes were arranged compactly in the apical part, forming spaces in the middle and basal parts of epithelium. Numerous mucous cells were scattered in the epithelium and there were intraepithelial lymphocytes (IELs) with their pseudopodia extended into the intestinal lumen. This study provides detailed features of intestinal epithelium in the that could be related to function. In addition, these findings are discussed in relation to other vertebrates.
通过光学显微镜和透射电子显微镜（TEM）研究了中华鳖肠道上皮的微观解剖结构。小肠上皮（SIE）为单层或假复层。肠细胞含有线粒体或线粒体与脂滴。肠细胞紧密排列在上皮的顶端部分，并通过桥粒和指状突相连。大肠上皮（LIE）为假复层，肠细胞不含脂滴。肠细胞紧密排列在顶端部分，在上皮的中部和基部形成空隙。大量黏液细胞散布在上皮中，并且有上皮内淋巴细胞（IELs），其伪足延伸到肠腔中。本研究提供了中华鳖肠道上皮可能与功能相关的详细特征。此外，还与其他脊椎动物相关地讨论了这些发现。
