In Vivo Imaging Reveals Existence of Crypt Fission and Fusion in Adult Mouse Intestine.

abstract：BACKGROUND & AIMS:Hydrogen sulfide is one of the main malodorous compounds in human flatus. This toxic gas also has been implicated in the pathogenesis of ulcerative colitis. Therefore, a treatment that reduces colonic H2S levels could be clinically useful in the treatment of flatus odor and of ulcerative colitis. In t...
