Tissue Engineering is the preeminent, biomedical advancing and applications on all aspects of tissue growth and regeneration. This multidisciplinary journal brings together the principles of engineering and life sciences in tissue development and regenerative medicine. Tissue Engineering provides a central forum for groundbreaking scientific research and developments of clinical applications from leading experts in the field that will enable contributions to the ultimate care of patients. The starting point for any tissue-engineered organ is the harvesting of small amounts of tissue from the future recipient of the Tissue Engineered organ. The ideal polymer scaffold is a so-called porous scaffold that consists of a nontoxic material having biocompatibility for not causing blood coagulation or inflammation after implantation. In addition, this scaffold has excellent mechanical properties to support the growth of cells. Moreover, in its form, this scaffold permits good adhesion of cells as well as sufficient space between cells to allow cells to access oxygen or nutrients through diffusion of body fluid and to form new blood vessels actively, which results in successful cell growth and differentiation. Furthermore, cells are generally cultured on a two-dimensional surface, but a three-dimensional scaffold is required to culture cells to become tissues or organs.
