What are crypts in colon?
Tube-like gland found in the lining of the colon and rectum. Colon crypt cells renew the lining of the intestine and make mucus. Also called gland of Lieberkuhn.
What is Paneth?
Paneth cells are highly specialized secretory epithelial cells located in the small intestinal crypts of Lieberkühn. The dense granules produced by Paneth cells contain an abundance of antimicrobial peptides and immunomodulating proteins that function to regulate the composition of the intestinal flora.
