title: [INTERSTITIAL CELLS OF CAJAL IN THE SMOOTH MUSCLE TISSUE OF THE GALLBLADDER AND BILE DUCTS].
abstract: Interstitial cells of Cajal (ICC) in the gallbladder and in different parts of the biliary tract were identified in adult guinea pigs by means of immunocytochemical reactions to specific marker of these cells--C-kit receptor tyrosine kinase (CD117) and electron microscopic analysis. It was shown that C-kit-positive cells were localized in the muscular component of the gallbladder wall and the various parts of the bile ducts. In the gallbladder wall their density was higher than in the bile ducts. ICC have numerous processes, and are characterized by the absence of the components of the contractile apparatus. They possess the capacity to form tight membrane contacts with smooth myocytes.
