Decellularization: Decellularization (also spelt decellularisation in British English) is the process used in biomedical engineering to isolate the extracellular matrix (ECM) of a tissue from its inhabiting cells, leaving an ECM scaffold of the original tissue, which can be used in artificial organ and tissue regeneration.  Organ and tissue transplantation treat a variety of medical problems, ranging from end organ failure to cosmetic surgery.  One of the greatest limitations to organ transplantation derives from organ rejection caused by antibodies of the transplant recipient reacting to donor antigens on cell surfaces within the donor organ.  Because of unfavorable immune responses, transplant patients suffer a lifetime taking immunosuppressing medication.  Stephen F. Badylak pioneered the process of decellularization at the McGowan Institute for Regenerative Medicine at the University of Pittsburgh.  This process creates a natural biomaterial to act as a scaffold for cell growth, differentiation and tissue development.  By recellularizing an ECM scaffold with a patient’s own cells, the adverse immune response is eliminated.  Nowadays, commercially available ECM scaffolds are available for a wide variety of tissue engineering.
