Recombinant Hepatocyte Growth Factor Accelerates Cutaneous Wound Healing in Diabetic Mouse Model

Researchers in Japan have discovered that recombinant hepatocyte growth factor (HGF) significantly accelerates cutaneous wound healing in a diabetic mouse model. The study found that topical administration of HGF, along with basic fibroblast growth factor (bFGF), promoted wound closure and re-epithelialization. Notably, HGF treatment enhanced expansion of granulation tissue, stimulated neovascularization, and increased microvessel density, whereas bFGF treatment remained effective even in later stages of wound healing.

Key Takeaways:

• Recombinant HGF significantly accelerates cutaneous wound healing in a diabetic mouse model.
• Topical administration of HGF, in conjunction with bFGF, promotes wound closure and re-epithelialization.
• HGF treatment enhances expansion of granulation tissue and stimulates neovascularization, whereas bFGF treatment remains effective in later stages of wound healing.
• Microvessel density in HGF-treated wounds was higher than in bFGF-treated wounds on day 7 postwounding.
• Matrix metalloproteinases (MMP-2 and MMP-9) activities involved in cell migration, angiogenesis, and extracellular matrix (ECM) remodeling were enhanced by HGF-treatment on day 7.
• DNA synthesis of fibroblasts in granulation tissue was stimulated by bFGF, but not by HGF, suggesting a lesser degree of susceptibility to cutaneous scarring.
• The authors propose that supplement of HGF may be a potential therapeutic approach for the treatment of cutaneous ulcers.
• S. Yoshida and colleagues published the results of their research in Growth Factors, a peer-reviewed journal.
