Granulocyte-colony stimulating factor (G-CSF) has been shown to have combinatorial trophic effects with dental pulp stem cells for pulp regeneration. The aim of this investigation is to examine the effects of basic fibroblast growth factor (bFGF)in vitroandin vivocompared with those of G-CSF and to assess the potential utility of bFGF as an alternative to G-CSF for pulp regeneration.MATERIALS AND METHODS:
Five different types of cells were examined in thein vitroeffects of bFGF on cell migration, proliferation, anti-apoptosis, neurite outgrowth, angiogenesis, and odontogenesis compared with those of G-CSF. Thein vivoregenerative potential of pulp tissue including vasculogenesis and odontoblastic differentiation was also compared using an ectopic tooth transplantation model.RESULTS:
Basic fibroblast growth factor was similar to G-CSF in high migration, proliferation and anti-apoptotic effects and angiogenic and neurite outgrowth stimulatory activitiesin vitro. There was no significant difference between bFGF and G-CSF in the regenerative potentialin vivo.CONCLUSIONS:
The potential utility of bFGF for pulp regeneration is demonstrated as a homing/migration factor similar to the influence of G-CSF.
