Crypt of intestine
The intestinal epithelium is part of the intestinal mucosa. The epithelium is composed of a single layer of cells, while the other two layers of the mucosa, the lamina propria and the muscularis mucosae, support and articulate the epithelial layer. To securely contain the contents of the intestinal lumen, the cells of the epithelial layer are joined together by tight junctions, thus forming a contiguous and relatively impermeable membrane. WebThe maintenance of intestinal function is associated with the normal intestinal morphology and structure, healthy intestinal barrier integrity and redox status. However, the present …

WebIn the intestine, crypts may also become more crowded with increased mitotic activity. However, these are subjective assessments and comparison to properly matched controls is important. PGE 2 is protective during this process by supporting proliferation and reepithelialization, which further explains the destructive effects of COX inhibitors.
