The first section of the volume consists of four chapters giving perspectives for the current status and potential future of tissue engineering and stem cell technologies. The second section of the volume includes five chapters based on experimental and clinical data. In this section, the role of stem cells in liver tissue engineering, cell-based therapies in diabetes mellitus, and chronic degenerative diseases of the central nervous system, and adult-derived stem cell therapies are discussed. The two chapters of the third section focus on the biomarkers for tissue-engineered products, namely for tissue-engineered skin. The eight chapters of the fourth section discuss novel biomaterials developed for neural-, vascular-, aortic-, bone-, cartilage- and endocrine pancreas-tissue engineering applications. The last section of the book includes chapters on practical gene targeting applications, controlled release in gene therapy and tissue engineering, antibodies in cancer, acute-phase genes and phage-displayed peptide libraries.
