Cardiac Regeneration and Stem Cells.

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 ...

Comparison of the effects of intramyocardial and intravenous injections of human mesenchymal stem cells on cardiac regeneration after heart failure

Objective(s): Existing studies have demonstrated that intravenous and intramyocardial-administrated mesenchymal stem cells (MSCs) lead to tissue repair after cardiac disorders. We compared the efficiency of both administration methods.Materials and Methods: A rat model of isoproterenol-induced heart failure (ISO-HF) was established to co...

Role of Stem Cells in Cardiac Cell Therapy and Tissue Engineering

Background: In spite of promising results of conventional treatments for myocardial infarction, including medications, stent implantation, and coronary artery bypass grafting, the disease and its complications, especially heart failure, are highly prevalent because these methods could not reverse the cell loss, which is the main problem. Currently, heart transplantation, as the last option f...

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

P-74: Effect of Fndc5 Overexpression onCardiac Differentiation Rate of mESCs

Background: Fibronectin type III domain-containing 5 proteins (Fndc5), an exercise hormone, formerly known as peroxisomal protein that was cloned in 2002. Transcript profile analysis of Fndc5 revealed high degree of expression in heart, skeletal muscle and brain. Our recent studies indicated a significant increase (approximately 10 folds) in mRNA level of Fndc5 when mouse embryonic stem cells w...

Stem Cells in Regenerative Endodontics

Background Currently, clinical endodontics includes procedures that are based on the ability of stem cells to accomplish repair (eg, direct pulp capping, apexogenesis, apexification, and even pulpal regeneration). An attempt is made to critically assess the current status in pulp regeneration therapy. Methods: Systematically, 2 distinctly different strategies exist involving stem cells for t...
