Tissue graft composition comprising autologous bone marrow and purified autologous thrombin

摘要

A method for the preparation of an autologous tissue graft composition is disclosed. Bone marrow is harvested from the patient. In one embodiment, the nucleated cells of the bone marrow are subsequently concentrated. Autologous thrombin is purified from a volume of whole blood also taken from the patient. The bone marrow aspirate or bone marrow concentrate is then combined with the purified autologous thrombin to form a coagulated tissue graft material that may be used alone or in conjunction with other graft materials.
