Stem cells and myocardial regeneration: cooperation wins over competition.

Are Stem Cells the next Therapeutic Tool for Heart Repair?

Cardiovascular disease remains the leading cause of morbidity and mortality in the United States and Europe. In recent years, the understanding that regenerative processes exist at the level of the myocardium, has placed stem cell research at center stage in cardiology. A stem cell is a cell that has the ability to divide (self replicate) for indefinite periods often throughout the life of the ...

Transplantation of Cardiogenic Pre-Differentiated Autologous Adipose-Derived Mesenchymal Stem Cells Induced by Mechanical Loading Improves Cardiac Function Following Acute Myocardial Infarction in Rabbit Model

Objective- Investigate myocardial performance after autologous adipose-derived (ASCs) mesenchymal stem cell differentiated under equiaxial cyclic strain, transplantation in rabbits with acute myocardial infarction (AMI). Design- Prospective, randomized experimental study Animals- 20 New Zealand White rabbits (2-3 kg) P...

Translation of Methdology used in Human Myocardial Imaging to a Sheep Model of Acute Myocardial Infarction

Background: Pre-clinical investigation of stem cells for repairing damaged myocardium predominantly used rodents, however large animals have cardiac circulation closely resembling the human heart. The aim of this study was to evaluate whether SPECT/CT myocardial perfusion imaging (MPI) could be used for assessing sheep myocardium following an acute myocardial infarction (MI) and response to int...

Amniotic Fluid Stem Cells and Their Application in Cell-Based Tissue Regeneration

Simultaneous delivery of Wharton’s jelly mesenchymal stem cells and insulin-like growth factor-1 in acute myocardial infarction

Wharton’s jelly mesenchymal stem cells (HWJMSCs) hold promise for myocardial regeneration, but optimal treatment regimen (preferably with a growth factor) is required to maximize functional benefits. The aim of this study was to explore the cardioprotective and angiogenesis effects of HWJMSCs combined with insulin-like growth factor-1 (IGF-1) in the treatment of acute myocardial infarction. Th...
