The book covers multifarious aspects of stem cell-based therapy for cardiovascular diseases. In addition to stem cells from different sources for cell-based therapy, it covers stem cell organoids and stem cell-derived exosomes in regenerative medicine. The book also encompasses advances in state-of-the-art infrastructure to improve the maturation aspects of pluripotent stem cells-derived cardiomyocytes using a novel scaffold-based cell culture system for cell delivery in experimental animal models and clinical settings. Besides the use of mesenchymal stem cells, the book includes chapters on the use of cardiac progenitor cells (CPCs), microtissue implantation, use of PSCs for valvulopathies, application of de-cellularized organ arrays as natural scaffolds for cardiac tissue engineering, use of epicardial stem cells, and skeletal myoblasts in cell-based therapy for myocardial regeneration. Besides the cell-based therapy approach, the book also reviews the stem cell-derived exosomes, their characteristics, and engineering strategies to enhance their therapeutic potential via targeting and drug loading and use in disease models. Additionally, the book also discusses the latest research on injectable hydrogels for cardiovascular regeneration and how hydrogel-based delivery protects the cells and their retention post-engraftment in the heart, a problem, which significantly reduces the efficacy of cell-based therapy.
