Human keratinocyte growth factor-2 (KGF-2) is a member of the fibroblast growth factor family that promotes healing of experimental small intestinal ulceration and colitis. The aim of this study was to determine whether repifermin, a truncated form of recombinant human KGF-2, reverses abnormalities in colonic mucosal transport in a murine model of dextran sulfate sodium (DSS)-induced colitis. Male Swiss-Webster mice were given 4% DSS in drinking water for 7 days and then normal drinking water for 3 days. Repifermin (5 mg kg(-1), i.p.) or vehicle was administered daily for 7 days starting on Day 4 of DSS exposure. On Day 10, net ion transport was measured electrophysiologically in colonic mucosal sheets. Repifermin significantly reduced DSS-induced colonic inflammation measured by tissue myeloperoxidase activity. Concurrently, in colonic tissue taken from mice treated with repifermin, there was a normalization of basal potential difference and short circuit current, and an improvement in the secretory responses to stimulation of muscarinic and ganglionic cholinoceptors. In control mice, repifermin did not interact directly with colonic epithelial cells or intramural neurones to induce immediate changes in net electrogenic transport. The results suggest that repifermin therapy may improve the mucosal electrogenic transport that is impaired during colitis.
