biostudies-literatureUnknown2025Wu CCardiac fibroblasts (CFs) are activated into cardiac myofibroblasts (CMFs) in myocardial infarction (MI) and promote fibrosis, playing a crucial role in deteriorating cardiac function and inducing fatal arrhythmias. Transplantation of bone marrow mesenchymal stem cells (BMSCs) has emerged as a promising therapeutic approach for ischemic heart diseases, including MI. Recent studies have indicated that BMSCs can modulate the survival, differentiation, and antifibrotic activity of CFs. Kruppel-like factor 5 (KLF5) is a significant transcription factor involved in maintaining stem cell properties. In this study, we aimed to investigate whether overexpression of KLF5 could enhance the cardioprotective characteristics of BMSCs, particularly in terms of mitigating structural and electrical remodeStem cells international5572221https://www.ebi.ac.uk/biostudies/studies/S-EPMC12357777biostudies-literatureKLF5 Regulation of Exosome-Derived miR-152-3p From Bone Marrow Stem Cells Improves Ventricular Arrhythmia After Myocardial Infarction.PMC12357777Jiang FWang YSZou XYWu CLin DWJiang YWfalseKLF5 Regulation of Exosome-Derived miR-152-3p From Bone Marrow Stem Cells Improves Ventricular Arrhythmia After Myocardial Infarction.Cardiac fibroblasts (CFs) are activated into cardiac myofibroblasts (CMFs) in myocardial infarction (MI) and promote fibrosis, playing a crucial role in deteriorating cardiac function and inducing fatal arrhythmias.
