Double Immunofluorohistochemistry With TUNEL and c-Kit in stomach tissues(×400 times). A: Group I=normal control rats; B. Group IV=normal + curcumin treated rats C. Group III=diabetic + curcumin treated rats. D. Group II=diabetic control rats; Representative images of TUNEL positive and c-kit positive ICC from sections of stomach tissues of diabetic rats.Red were c-kit positive cells in tissues. Green were apoptotic cells in tissues.Yellow were TUNEL positive and c-kit positive apoptotoc ICCs.Numbers of TUNEL positive and c-kit positive apoptotic ICCs(yellow stain)expressed as the % of total number of ICCs in the circular muscle layer of each section. Yellow-stained ICCs are undergoing apoptosis.
