A Dopamine-Methacrylated Hyaluronic Acid Hydrogel as an Effective Carrier for Stem Cells in Skin Regeneration Therapy

This study found that combining ultrasound with a GelMA hydrogel able to deliver mesenchymal stem cell-derived vesicles significantly improved wound healing in a mouse model by enhancing fibroblast activity, promoting re-epithelialization, and facilitating hair follicle regeneration, highlighting a novel approach to skin regeneration therapy.

In this study, researchers developed a novel method using ultrasound stimulation and a hydrogel delivery system to enhance the regenerative effects of stem cell-derived extracellular vesicles on severe skin injuries, resulting in improved healing and hair follicle regeneration in a mouse model.

In this study, the researchers developed a hydrogel mimicking the fetal environment that significantly accelerated wound healing and hair follicle regeneration in vivo, with over 94% wound closure in 14 days, surpassing hydrogels lacking certain additives.

This study found that exosome-incorporated human amniotic membrane scaffolds notably enhanced diabetic skin wound healing in mice, suggesting potential applications for ADSC-derived exosomes in clinical settings.

This study found that gelatin microspheres delivering adipose-derived stem cells significantly accelerated diabetic wound healing in rats, suggesting a promising approach for enhancing cell-based therapies.
