RESUMO
Fibroblast growth factor 2 (FGF-2) is a multifunctional protein that has major roles in wound healing, tissue repair, and regeneration. This therapeutic protein is widely used for burn treatment because it can stimulate cell proliferation and differentiation, angiogenesis, and extracellular matrix remodeling. In this study, we developed a simple method using a controlled heated brass rod to create a homogenous third-degree burn murine model and evaluated the treatment using recombinant human FGF-2 (rhFGF-2). The results indicated that the wound area was 0.83 ± 0.05 cm2 and wound depth was 573.42 ± 147.82 µm. Mice treated with rhFGF-2 showed higher rates of wound closure, granulation tissue formation, angiogenesis, and re-epithelialization than that of phosphate-buffered saline (PBS)-treated group. In conclusion, our lab-made rhFGF-2 could be a potentially therapeutic protein for burn treatment as well as a bioequivalent drug for other commercial applications using FGF-2.
