a method of forming and preserving a bioremodelable , biopolymer scaffold material is carried out by subjecting animal tissue , particularly fetal or neo - natal tissue , to chemical and mechanical processing . the process may include , but is not limited to , harvesting the tissue , optionally extracting growth and differentiation factors from the tissue , inactivating infective agents of the tissue such as by treating with koh or naoh , mechanically expressing undesirable components from the tissue , delipidizing the tissue with organic solvents , mechanically expressing components released by the solvet , washing the tissue , optionally drying the tissue , and optionally cross - linking the tissue , not necessarily in the order described . the resulting product , named eb matrix , is characterized by its microbial , fungal , viral and prion inactivated state . ebm is strong , bioremodelable , drapable and does not undergo calcification .
