Background: The regenerative capacity of the mammalian heart is quite limited. Recent reports have focused on reprogramming mesenchymal stem cells into cardiomyocytes. We investigated whether fibroblasts could transdifferentiate into myocardium.Methods: Mouse embryonic fibroblasts were treated with Trichostatin A (TSA) and 5-Aza-2-Deoxycytidine (5-aza-dC). The treated cells were permeabilized w...
Cardiomyocyte regeneration is limited in adult life. Thus, the identification of a putative source of cardiomyocyte progenitors is of great interest to provide a usable model in vitro and new perspective in regenerative therapy. As adipose tissues were recently demonstrated to contain pluripotent stem cells, the emergence of cardiomyocyte phenotype from adipose-derived cells was investigated. W...
Coronary heart disease is major cause of mortality worldwide and several risk factors have been shown to play a role in its pathogenesis, including smoking, obesity, hypertension and hypercholesterolemia. A number of therapeutic methods have been developed to improve the quality of patients' lives, including stem cell therapy using mesenchymal stem cells (MSCs). Perinatal sources, including the...
Introduction: Numerous studies have shown that enriched plasma protects myocardial cells against ischemia. The aim of this study was to evaluate the effect of rat enriched plasma by preconditioning, ischemia, and reperfusion on the differentiation of bone marrow mesenchymal stem cells (BMMSC) into cardiomyocytes. Methods: In this experimental and laboratory study, BMMSCs were extracted from th...

left ventricular rat heart tissue.(9) While the cells do not beat and differ morphologically from isolated adult cardiomyocytes, similarities with primary cardiomyocytes have been reported, specifically in terms of the presence and dynamics of L-type calcium channels, a similar cell membrane lectin binding pattern and comparable G-protein composition associated with ligand stimulated intracellu...
introduction: doxorubicin is frequently used for treatment of several types of cancer. doxorubicin cardiac toxicity has limited the use of this drug. corticosteroids may prevent doxorubicin induced cardiotoxicity. therefore the aim of this study was to evaluate mouse embryonic stem cells derived cardiomyocytes as a model to evaluate the effect of doxorubicin and dexamethasone. methods: mouse em...
Myocardial infarction results in extensive cardiomyocyte death which can lead to fatal arrhythmias or congestive heart failure. Delivery of stem cells to repopulate damaged cardiac tissue may be an attractive and innovative solution for repairing the damaged heart. Instructive polymer scaffolds with a wide range of properties have been used extensively to direct the differentiation of stem cell...
