Research Abstract |
In this study, we examined whether FGF-2 could induce vascular endothelial growth factor (VEGF)-A expression in periodontal ligament (PDL) cells and whether cell-to-cell interaction between PDL cells and endothelial cells (EC) could stimulate angiogenesis. FGF-2 induced VEGF-A expression from PDL cells. FGF-2 and VEGF-A synergistically stimulated the migration of PDL cells. Time-lapse analysis revealed that PDL cells migrated close to the tube-forming EC, mimicking pericytes. These findings suggest that FGF-2 and FGF-2-induced VEGF-A, as well as cell-to-cell interactions between PDL cells and EC, create a suitable environment of periodontal regeneration by orchestrating angiogenesis at FGF-2-applied sites.
