Tissue engineering aims to create medical devices that, once implanted, will replace or enhance tissue function that has been impaired by disease, injury, or age. The book then turns to important areas of tissue engineering with respect to case studies on individual tissues and organs. There are chapters that specifically discuss skin, cartilage, bone, the nervous system, and various organ systems. Important ethical issues in tissue engineering are discussed.The book also examines the important issue of tissue compatibility and biomaterials compatibility which with the body. In addition, scaffold design and fabrication are discussed so that the reader may have a better understanding of how to develop and manufacture these systems. Ways of using controlled release from materials is examined; controlled release of different factors (e.g. growth factors to promote vascularization) can provide an important means of controlling and improving tissue function.
