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

Figure 2 Expression of tyrosine kinase receptor and cholecystokinin-A receptors in common bile duct cultured cells determined by immunofluorescence. A: Interstitial Cajal-like cells (ICLCs) are tyrosine kinase receptor-positive (green); B: ICLCs express cholecystokinin-A receptors (red); C: Synthetic micrographs of A and B; D: Phase-contrast micrographs of A and B.
