Abstract:
BACKGROUND:Application of mechanical valve and bioprosthetic valve replacement is an effective means for the treatment of end-stage valve disease. However, their clinical application is constrained by multiple factors. Tissue-engineered heart valves with biological activity hold the potential to overcome the defect of the mechanical valves and bioprosthetic valves. Choosing appropriate cells for cellseeding is a significant aspect for the research of tissue-engineered heart valves. A growing number of somatic cells and stem cells have been used for construction of tissue-engineered heart valves, however, not yet achieve the desired result.
OBJECTIVE:To review the studies on seed cells for tissue-engineered heart valves and the cellseeding methods in vitro on the basis of the cellular components of heart valves.
METHODS:First author searched PubMed and Wanfang database with computer for related articles published from January 2000 to December 2012. The keywords were“tissue engineering, heart valves, cel”. Preferred articles concerned seed cells of tissue-engineered heart valves with the relevance and authority. A total of 39 articles published in the prestigious journals were reviewed.
RESULTS AND CONCLUSION:Endothelial cells and interstitial cells were mainly valvular cellular components. In the early stage, endothelial cells and fibroblasts were used to construct tissue-engineered heart valves. With deep stem cellresearch, the application of pulsatile bioreactor cultivation mesenchymal stem cells holds a great potential to produce tissue-engineered heart valves.
