Percutaneous tissue-engineered pulmonary valved stent implantation: comparison of bone marrow-derived CD133+-cells and cells obtained from carotid artery.

Objective: The aim of tissue engineering is, for instance, to create a new valve or organ that is similar to the native one. This new construct may have the capability of growth, repair, and remodeling. One instance where tissue engineering offers an enormous advantage is in the treatment of Tetralogy of Fallot.
