Bone marrow of Acute myeloid leukemia(MI): The myeloid blast>90%, were round or oval, somewhat larger, abundant cytoplasm of opaque blue and non-particle. We can see some large vacuoles. Nucleus were oval or irregular in shape sometime with large and clear nucleoli, and the nuclear staining articles were of small size

Bone marrow of Acute myeloid leukemia(M2): type I and type 2 blasts were>30%. Progranulocyte and its myeloid following were >10%. Auer body can sometimes be observed. There are three cells in the picture above have Auer body in their cytoplasm

Bone marrow Acute myeloid leukemia(M2b): This type was temporarily named according to he proposal of Tianjin Hematology meeting, formerly t known as a sub-acute myeloid leukemia. Myelocytes of increased volume and of nuclear-cytoplasmIc development imbalance were mainly observed Such cell have been developed to promyelocytic stage, but the development of nucleus was later than cytoplasm
