Bone marrow aspirates of 50 non-malignant cases, 25 MDS patients and 50 AML patients were subjected to ten-color/twelve-parameter flow cytometry for the analysis of the Ki-67 proliferative indices and Bcl-2 anti-apoptotic indices in CD34 positive blast cells, erythroid cells, myeloid cells and monocytic cells. Data were acquired with the NAVIOS Flow cytometer (Beckman Coulter, Marseille, France).
