Neutrophilic infiltration of crypts (cryptitis) often accompanied by crypt abscesses, depletion of goblet cell mucin, and chronic inflammatory cells in the lamina propria constitute the primary histologic findings in UC (Figure 45-3).In addition, signs of …
WebIn histology, an intestinal crypt—called the crypt of Lieberkühn—is a gland found in the epithelial lining of the small intestine and colon. The crypts and intestinal villi are covered by epithelium that contains two types of cells: goblet cells that secrete mucus and enterocytes that secrete water and electrolytes. WebInvagination consists of the folding of an area of the exterior sheet of cells towards the inside of the blastula. In each organism, the complexity will be different depending on the number of cells. Invagination can be …
