Abstract
Keratinocyte growth factor (KGF) is emerging asan important mediator of mucosal defense and repair inthe colon. The aim of the present study was to evaluateand further characterize the effects of exogenous KGF administration utilizing the dextran sodiumsulfate (DSS) model of colitis in mice. Colitis wasinduced via oral administration of DSS (5 g/100 ml) toBalb/c mice for eight days. Intraperitonealadministration of KGF (5 mg/kg, once daily) or vehicle (VEH)was initiated 1 hr prior to the induction of the colitis(N = 10, each group). Mucosal injury of the entire colonwas histologically assessed and graded. An approximately fourfold reduction in the cryptdamage score was noted in the KGF group when compared tocontrols (VEH) (2.8 ± 1.03 and 11.4 ±0.78, respectively). The significant reduction ofmucosal injury in KGF treated mice confirms that KGF isa key mediator maintaining the integrity of the colonicmucosa.
