Fig. 7

 A comparison of NPY staining in sections of human (A-B) and porcine (C-F) spleen. NPY + sympathetic nerves are associated with splenic vasculature, like TH, in human spleen. A NPY + nerve staining around central arterioles (arrows) in section from donor 002 spleen. Few nerves extend a short distance into the surrounding parenchyma. B NPY + nerves around a central arteriole in section from donor 004 spleen. C Robust staining for NPY + nerves throughout the red pulp (rp) of pig spleen. White pulp (wp) has considerably less NPY staining. D Sympathetic nerves stain for NPY near and extending from central arterioles, indicated by arrows, within the white pulp. E The capsule does not contain NPY + innervation, but the red pulp beneath the capsule and the central arteries (ca.) extending from the capsule are heavily innervated. F Sympathetic nerves run parallel to trabeculae (t) in pig spleen parenchyma
