In this group, the bone marrow aspirate will be sent to the laboratory to be grown in tissue culture. Once the cell cultures have matured (within 8 weeks) they will be checked for sterility and frozen until applied to the subject wound. Up to three applications of cultured cells will be applied to the wound following the bone marrow biopsy. A single treatment cycle will consist of up to three applications of cultured cells derived from a single bone marrow aspiration. If the wound has not healed, up to three additional treatment cycles may be performed. Each bone marrow biopsy will be followed by up to three applications of cultured cells (prepared from the most recent bone marrow biopsy). If the wound should heal at any point during this protocol, no additional bone marrow biopsy procedures will be performed and no additional cells will be applied.
