ABSTRACT
The management of diabetic wounds presents a formidable challenge in clinical settings due to elevated glucose levels, drug-resistant bacterial infections, and a deficiency of bioactive molecules in the microenvironment. To address this challenge, a glucose-responsive Hyaluronic acid Methacryloyl (HAMA)-Chitosan Methacryloyl (CSMA)-3-Methacrylamidophenylboronic acid (MPBA) loading Exosome (H-C-M@Exo) multifunctional hydrogel has been developed to enhance diabetic wound healing in this study. The H-C-M@Exo hydrogel exhibits remarkable features, including high hydrophilicity, excellent pressure resistance, antibacterial properties, and good biocompatibility. It uniquely possesses the ability to sustain the release of exosomes in response to glucose fluctuations. The H-C-M@Exo hydrogel can effectively reduce inflammation, significantly promote rapid re-epithelization, facilitate favorable collagen deposition, and stimulate abundant angiogenesis at the wound sites. Furthermore, the hydrogel induces localized regulation of M2 macrophage polarization, synergistically promoting diabetic angiogenesis and wound healing. These findings suggest H-C-M@Exo hydrogel is a promising biomaterial for the treatment of chronic diabetic wounds.
