Research Abstract

To assess the participation of stromal components in the progression of oral squamous cell carcinoma(SCC) cells, we investigated the effect of fibroblasts on the proliferation, motility and proteolytic activity of SCC cells. Fibroblasts in the stroma of oral SCC synthesize TSP-1, which induces haptotactic migration and enhances the ability to synthesize matrix metallopeptidase 9(MMP-9) in oral SCC cells. Further type I collagen produced by fibroblasts facilitates the proliferation and migration of oral SCC cells via integrinαvβ8
