Cell transplantation for heart failure,and tissue engineering of cardiovascular structures

The emergence of selective cell transplantation and tissue engineering has opened up new alternatives for the treatment of heart failure. These involve the use of stem and progenitor cells, as well as new biodegradable polymer scaffolds. The last two decades have seen a dramatic increase in our knowledge of how to fabricate a wide array of tissues, including cardiovascular structures. This article reviews current trends in selective cell transplantation and tissue engineering, and summarises recent achievements and remaining questions in constructing functional cardiac tissue.
