It has been generally accepted that basic fibroblast growth factor is a potent stimulator of duodenal ulcer healing. However, the detailed mechanism and mode of action of growth factor on gastric ulcer healing is still controversial. Therefore, in the present study, the effects of basic fibroblast growth factor on gastric mucosal repair were studied using an in vitro cultured cell system. Artificial wounds were made in confluent monolayer rabbit gastric fibroblast and epithelial cell sheets by mechanical denudation. Changes in the size of the cell‐free area were analysed quantitatively. Cell proliferation was assessed by BrdU staining. For both cell types, mucosal restoration involved cell migration and proliferation. Although the speed of restoration of epithelial cells was not affected by the addition of basic fibroblast growth factor, it was much faster for epithelial cells than for fibroblasts. Basic fibroblast growth factor accelerated wound repair of fibroblasts but not epithelial cells. Basic fibroblast growth factor accelerated wound repair by stimulating both cell migration and proliferation. Therefore, the effects of basic fibroblast growth factor in peptic ulcer diseases may be mainly due to the stimulation of mesenchymal cells.
