Abstract
Decellularized tissues and organs have been successfully used in various tissue engineering and regenerative medicine applications. A biological scaffold obtained from the extracellular matrix can be produced by a variety of decellularization methods that effectively remove cells from the tissue to be treated. Decellularization methods is changed according to the target structure of tissues and organs. These methods can be summarized with chemically, physically, enzymatically and using Supercritical Fluid Extraction (SFE) ways. Each of these methods affects the biochemical composition in the structure of the remaining extracellular matrix (ECM), the structure of the tissue (ultrastructure), and the mechanical behavior. In this article, the most commonly used decellulization methods are introduced and their effects on biological tissue scaffold materials are discussed.
