  • Title: Human embryonic stem cells for cardiomyogenesis.
    Author: Habib M, Caspi O, Gepstein L.
    Journal: J Mol Cell Cardiol; 2008 Oct; 45(4):462-74. PubMed ID: 18775434.
    Abstract:
    Myocardial cell replacement strategies are emerging as novel therapeutic paradigms for heart failure but are hampered by the paucity of sources for human cardiomyocytes. Human embryonic stem cells (hESC) are pluripotent stem cell lines derived from human blastocysts that can be propagated, in culture, in the undifferentiated state under special conditions and coaxed to differentiate into cell derivatives of all three germ layers, including cardiomyocytes. The current review describes the derivation and properties of the hESC lines and the different cardiomyocyte differentiation system established so far using these cells. Data regarding the structural, molecular, and functional properties of the hESC-derived cardiomyocytes is provided as well as description of the methods used to achieve cardiomyocyte enrichment and purification in this system. The possible applications of this unique differentiation system in several cardiovascular research and applied areas are discussed. Specific emphasis is put on the descriptions of the efforts performed to date to assess the feasibility of this emerging technology in the fields of cardiac cell replacement therapy and tissue engineering. Finally, the obstacles remaining on the road to clinical translation are described as well as the steps required to fully harness the potential of this new technology.
