Abstract
Introduction
The skin plays a crucial role as a protective barrier against external factors, but disruptions to its integrity can lead to wound formation and hinder the natural healing process. Scar formation and delayed wound healing present significant challenges in skin injury treatment. While alternative approaches such as skin substitutes and tissue engineering exist, they are often limited in accessibility and cost. Exosomes have emerged as a potential solution for wound healing due to their regenerative properties.
Methods
In this study, exosomes were isolated from human blood serum using a kit. The exosomes were characterized, and their effects on cell migration were assessed in vitro. Additionally, the wound healing capacity of exosomes was evaluated in vivo using a rat full-thickness wound model.
Results
Our in vitro findings revealed that exosomes significantly promoted cell migration. In vivo experiments demonstrated that the injection of exosomes at different areas of the wound accelerated the wound healing process, resulting in wound closure, collagen synthesis, vessel formation, and angiogenesis in the wound area. These results suggest that exosomes have a promising therapeutic potential for expediting wound healing and minimizing scar formation.
Conclusions
The findings of this study highlight the potential of exosomes as a novel approach for enhancing wound healing. Exosomes showed positive effects on both cell migration and wound closure in in vitro and in vivo studies, suggesting their potential use as a regenerative therapy for skin injuries. Further research is needed to fully understand the mechanisms underlying the beneficial effects of exosomes on wound healing and to optimize their application in clinical settings.
