Effect of PNS denervation on intestinal epithelial crypt cell proliferation. (a) Intestinal tissue immunohistochemically processed with an anti-BrdU antibody to visualize intestinal epithelial crypt cell proliferation. Tissue counterstained with hematoxylin. (b) Average proliferating crypt cell number in the jejunum was increased in PNS denervated animals compared with pair-fed sham animals (P < 0.05). (c) There were no differences between groups in average proliferation ratio in the duodenum, jejunum, or ileum. (d) There were no differences between groups in average total crypt cell number in the duodenum, jejunum, or ileum
