CD33 and acute myeloid leukemia: After five weeks of xenotransplantation, the antileukemic efficacy of EA or Na2EA against THP-1 ASID mice was significant when monitoring PB CD33 + or CD45 + cells (Fig. 6B C, respectively); however, only Na2EA is capable of reducing THP-1 AML cells in the bone marrow when monitoring both BM CD33 + and CD45 + AML cells (Fig. 6D and E, respectively).
