FIG. 1.

Gpr40 is expressed in gut enteroendocrine cells. A: X-gal staining of sections of pylorus, duodenum, jejunum, ileum, and colon in 2-month-old Gpr40+/+ and Gpr40+/lacZ mice. B: In situ hybridization using Gpr40-specific probes on sections of neonatal epithelium in stomach and duodenum. Arrows indicate cells expressing Gpr40 mRNA. C: Confocal sections of 2- to 3-month-old adult Gpr40+/lacZ pylorus and duodenum stained with anti–β-gal antibodies (green) to indicate Gpr40 expression and antibodies specific for the indicated enteroendocrine hormones (red).
