Cellular cardiomyoplasty, or cell-based cardiac repair, is a new potential therapeutic modality in which progenitor cells are used to repair regions of damaged or necrotic myocardium. The ability of transplanted progenitor cells to improve function within the failing heart has been shown in experimental animal models and in some human clinical ...
The use of hECTs in generating tissue engineered heart valves is also being explored to improve current heart valve constructs for in vivo animal studies. [20] As tissue engineering technology advances to overcome current limitations, hECTs are a promising avenue for experimental drug discovery, screening and disease modelling and in vivo repair.
Endogenous cardiac stem cells were first discovered in 2003 by Bernardo Nadal-Ginard, Piero Anversa and colleagues [2] [3] in the adult rat heart and since then have been identified and isolated from mouse, dog, porcine and human hearts. [4] [5] The adult heart was previously thought to be a post mitotic organ without any regenerative capability.
Research is underway to develop various sources for stem cells as well as to apply stem-cell treatments for neurodegenerative diseases [4] and conditions such as diabetes and heart disease. Stem-cell therapy has become controversial following developments such as the ability of scientists to isolate and culture embryonic stem cells, to create ...
Adult stem cells were extracted from the patient's bone marrow, grown into a large population, and matured into cartilage cells, or chondrocytes, using an adaptive method originally devised for treating osteoarthritis. The team then seeded the newly grown chondrocytes, as well as epithelial cells, into a decellularised (free of donor cells ...
Valve interstitial cells (VIC), cardiac valve interstitial cells, or also known as valvular interstitial cells (VICs), are the most prevalent cells in the heart valve leaflets, which are a type of mesenchymal stem cells (MSCs) and are responsible for maintaining the extracellular matrix that provides the mechanical properties of the heart valve.
