Pretreatment of Human Umbilical Cord Mesenchymal Stem Cell-Derived Exosomes with Quercetin Enhances the Healing of Diabetic Skin Wounds by Modulating Host-Microbiota Interactions

Owing to the distinctive advantages of mesenchymal stem cell-derived exosomes (MSCs-exo), these vesicles have emerged as a pivotal research focus in regenerative medicine, surpassing their MSC counterparts. Quercetin (Qr), widely recognized for its potent anti-inflammatory and antioxidant activities, demonstrates substantial potential in enhancing tissue repair processes. This study delves into the role of quercetin-pretreated MSC-derived exosomes (MSCs
