ECM Biomaterial

From Wikipedia, the free encyclopedia

ECM biomaterials are a class of biomaterials derived from processing human or animal tissues to retain portions of the extracellular matrix. These materials are typically cell-free, distinguishing them from classical allografts and xenografts, can be integrated or incorporated into the body, and have been FDA approved for human use for more than 10 years in a wide range of clinical indications.[1]

Development[edit]

Classic Tissue Engineering and Regenerative Medicine research combines cells and scaffolds, induced to grow with biochemical and mechanical stimuli, in a laboratory setting for organ repair and replacement. Due to complexities in bringing a successful tissue engineered organ to market, only limited clinically available devices meet this classic definition (for example: artificial skin, sold for limited indications in the healing of venous leg and diabetic foot ulcers.[2]) However, the approach of implanting cell-free scaffolds, with or without growth factors has become a regular part of clinical practice in healing patients in a wide range of applications including, but not limited to, hernia repair,[3] skin and wound healing,[4] breast reconstruction,[5][6] tendon repair,[7] and bone healing.[8] ECM biomaterials are derived from the extracellular matrix of human or animal tissues, and processed to remove unwanted components of the tissues and retaining desired components. Versions of these materials have been on the FDA approved since 1996 for soft tissue repair devices,[9] and 1991 for demineralized bone grafts.[10]
