Ganglia in the porcine GI-tract. A–C: jejunal submucous ganglion immunostained for CART (A), and VIP (B), merged in C. D–F: Myenteric ganglion in antrum of the stomach immunostained for CART (D) and NOS (E), merged in F. G–I: Myenteric ganglion of the ileum immunostained for CART (G) and VIP (H), merged in I. Note that CART IR is colocalised with both NOS IR and VIP IR in nerve cell bodies and fibres innervating the nerve cell bodies. Colocalisation exemplified with arrowheads. Scale bar = 25 μm.
