Objective:

To develop a multifunctional hyaluronic acid-based hydrogel that enhances cellular adhesion and provides localized antimicrobial activity to accelerate the healing of diabetic foot ulcers (DFUs).

Key Findings:
  • AcHyA-G hydrogels exhibited rapid gelation, elastic properties, and consistent molecular diffusion.
  • The presence of gelatin improved hydrogel stability without altering degradation profiles.
  • 0.5% gelatin concentration was optimal for supporting cell adhesion and spreading.
  • Incorporation of AMP conferred bactericidal activity against S. aureus.
Interpretation:

The multifunctional AcHyA hydrogels show potential as effective wound dressings for DFUs, providing structural support, enhanced bioactivity, and localized antimicrobial effects.

Limitations:
  • The study primarily focused on in vitro assessments; pre-clinical models are needed for further validation.
  • Long-term effectiveness and safety in clinical settings remain to be evaluated.
Conclusion:

AcHyA hydrogels functionalized with gelatin and antimicrobial peptides demonstrate promising potential for promoting the healing of chronic wounds, warranting further research in pre-clinical models.
