Figure 1 Analysis of chromogranin A co-expression in mouse small intestinal endocrine subpopulations. Small intestine sections of adult control mice were co-immunostained with antibodies directed against ghrelin (GHR) (A), cholecystokinin (CCK) (D), gastrin-releasing peptide (GRP) (G), secretin (SCT) (J) glucose-dependent insulinotropic peptide (GIP) (M) or somatostatin (SST) (P) and against chromogranin A (CgA) (respectively B, E, H, K, N and Q). The arrows in images C, F, I and L show co-expression of CgA respectively with GHR, CCK, GRP and SCT while asterisks in images F, I, L, O and R point to CgA-negative enteroendocrine cells. The number of arrows and asterisks within the crypt-villus axis represents the average proportion of labelled cells per units. Scale bar: 50 μm.
