Abstract

Previous human and animal studies have demonstrated the ability of exogenously administered basic fibroblast growth factor (FGF2) to act as an antifibrotic agent in the skin. Though the activity of FGF2 as an anti-scarring agent is well-established for fibrotic skin wounds, the mechanisms by which FGF2 exerts these actions are not entirely understood. Canonical FGF2 signaling proceeds in part via FGFR/MAPK pathways in human dermal fibroblasts, and FGF2 has been described to prevent or reverse the fibroblast-to-myofibroblast transition, which is driven by TGFβ signaling and understood to be an important step in the formation of a fibrotic scar in vivo. Thus, we set out to investigate the antagonistic effects of FGF2 on TGFβ signaling as well as the broader effects of MAPK inhibition on the TGFβ-mediated induction of myofibroblast gene expression.
