Effects of cisapride on jejunal motor activity in fasting healthy humans.

abstract：:The intestinal epithelium is a repetitive sheet of crypt and villus units with stem cells at the bottom of the crypts. During postnatal development, crypts multiply via fission, generating 2 daughter crypts from 1 parental crypt. In the adult intestine, crypt fission is observed at a low frequency. Using intravital mi...
