Porcine adrenal gland immunostained for CART (A, D, G) and VIP (B, E, H); merged in C, F, and I. A–C: CART is colocalised with VIP in fibers within a ganglion in the capsule. Note also CART containing nerve cell bodies devoid of VIP. D–F: CART is colocalised with VIP in fibers in the cortex. G–I: In the medulla most VIP IR fibers are devoid of CART. Colocalisation exemplified with arrowheads. Scale bars = 20 μm.
