Expression and functional study of cholecystokinin-A receptors on the interstitial Cajal-like cells of the guinea pig common bile duct

Figure 1 Expression of tyrosine kinase receptor and cholecystokinin-A receptors in gallbladder tissue sections determined by immunofluorescence. A: Tyrosine kinase receptor-positive cells (green) in the muscularis layer of the gallbladder; B: Cholecystokinin-A receptor-positive cells (red) were mainly located in the muscularis layer of the gallbladder; C: Synthetic micrographs of A and B; D: Phase-contrast micrograph of A and B.
