The article “The safety and efficacy of mesenchymal stem cell therapy in diabetic lower extremity vascular disease: a meta-analysis and systematic review” examines the effectiveness of MSC therapy for diabetic patients with lower extremity vascular disease (LEVD). The meta-analysis of 10 studies involving 453 patients found that MSC therapy significantly improves ulcer healing rates, blood supply, and the number of new collateral vessels without increasing adverse events. MSC therapy was shown to promote ulcer healing, improve blood supply, and have a favorable safety profile.
