Cell Therapy And Methods Of Stem Cell Delivery For Regeneration Of Heart Tissue Following Myocardial Infarction

Myocardial infarction (MI) results in irreversible loss of cardiomyocytes (CMs) and can often lead to heart failure. Due to the minimal regeneration capacity of the myocardium, novel therapeutic techniques are needed. Cell therapy has emerged as a promising treatment for MI and involves the introduction of stem cells into the infarct area where they can proliferate and regenerate functional heart tissue. These cells can be delivered by various methods, including direct injection, scaffold formation, and cell sheet preparation. Of these, cell sheet technology appears to hold the most promise as it allows for maximal cell engraftment and retention without significant harmful side effects. Furthermore, the best composition of the cell sheet has since been debated. Cell sheets composed of skeletal myoblasts (SMs), mesenchymal cells (MSCs), and pluripotent stem cells, such as embryonic stem cells (ESCs) and induced pluripotent stem cells
