[Application of hydrogel-loaded stem cell exosomes in the field of tissue regeneration].

Mesenchymal stem cell-derived exosomes may enhance tissue regeneration when combined with hydrogel.

• Exosomes serve as signaling molecules that aid in communication between cells.
• They exhibit natural targeting abilities and low immunogenicity, facilitating their uptake by cells.
• The combination of exosomes and hydrogel may improve the retention time and dosage of exosomes at injury sites.
• This composite could result in a significant and sustained therapeutic effect in tissue repair.
