The basic concept of regenerative medicine and tissue engineering is intriguing for physicians and scientists as it involves healing tissues or organ defects that the present medical practice finds difficult or impossible to cure. Tissue engineering involves cells, materials methods and engineering supported by appropriate physiochemical and biological factors to enhance or replace biologic functions. Regenerative medicine is a new division of medicine which aims to change the course of chronic disease and regenerate failing organ systems lost due to damage, age, disease and congenital defects. This book reflects state-of-the-art of these two disciplines at this time, as well as their therapeutic application. It discusses various topics under scaffolds and matrices. This book provides as a reference for physicians, scientists and students and as an explanatory analysis for individuals in pharmaceuticals and biotech companies.
