Tissue engineering and regenerative medicine uses a combination of cells, scaffolding and bioreactive factors to treat a variety of pathological conditions and has become a treatment option for many adult diseases. In this book, the authors present current research from across the globe, in the study of the fundamentals, techniques and applications of tissue engineering. Topics discussed in this compilation include the characterization of liver organogenesis and foetal and adult stem/progenitor cells; in vitro biological activity of double and triple component system scaffolds in bone tissue engineering; stretching bioreactors for dynamic engineering of muscle tissues; adipose-derived stem cells and their application in tissue engineering; regenerative medicine and tissue engineering for congenital birth defects.
