To obtain a metabolic fingerprint of AML, we performed intracellular metabolic profiling of leukemic cells (35 CD34+ and 15 CD33+ isolated bone marrow (BM) blasts) and compared them with 21 normal cord blood (CB) CD34+ and 21 normal CD33+ peripheral blood (PB) samples from healthy subjects. Here, CD34 is linked to acute myeloid leukemia.
