Homing of the Bone Marrow-Derived Interstitial Cells of Cajal is Decreased in Diabetic Mouse Intestine

摘要

BackgroundInterstitial cells of Cajal (ICCs), which express c-Kit receptor tyrosine kinase (KIT), play an important role in gastrointestinal motility. Loss of ICCs likely contributes to diabetic gastrointestinal motility disorder, however, the mechanism of attrition remains unknown. Here, we test the hypothesis that the bone marrow-derived progenitors are an important source of intestinal ICCs and that decreased homing of these progenitors in diabetes contributes to ICC diminution.
