Efficacy of mesenchymal stem cell therapy on glucose levels in type 2 diabetes mellitus: A systematic review and meta‐analysis

Abstract

Abstract Aims/Introduction In recent years, mesenchymal cellular therapies have received much attention in the treatment of diabetes. In this meta‐analysis, we aimed to evaluate the efficacy of mesenchymal stem cell therapy in type 2 diabetes mellitus patients. Materials and Methods A comprehensive literature search was carried out using PubMed, Scopus, Web of Science and Central databases. A total of 1,721 articles were identified, from which nine full‐text clinical trials were qualified to enter the current meta‐analysis. The assessment groups included patients with type 2 diabetes, and levels of C‐peptide, glycosylated hemoglobin and insulin dose were analyzed before and after mesenchymal stem cell infusion. Data analysis was carried out in Stata version 11, and the Jadad Score Scale was applied for quality assessment. Results Changes in levels of C‐peptide after mesenchymal stem cell therapy were: standardized mean difference 0.20, 95% confidence interval −0.61 to 1.00, glycosylated hemoglobin levels were: standardized mean difference −1.45, 95% confidence interval −2.10 to −0.79 and insulin dose were: standardized mean difference −1.40, 95% confidence interval −2.88 to 0.09. Conclusions This meta‐analysis of prospective studies showed associations between mesenchymal stem cell therapy and control of glucose level in patients with type 2 diabetes.
