In mice, widespread deletion of the tumor suppressor Phosphatase and tensin homolog (PTEN) generates hamartomatous intestinal polyps with epithelial and stromal inolement.
The small intestine was gained to make microtome section and mucous membrane of small intestine morphology, trophonema altitude, thickness and crypt shade were observed under light microscope.
The inferior ileocecal recess is bounded in front by the ileocecal fold, above by the posterior ileal surface and its mesentery, to the right by the cecum, and behind by the upper mesoappendix (22).
