Neutrophilic granulocytes in peripheral blood smear (human) | Stain: May-Grnwald-Giemsa (MGG). The nucleus of the neutrophilic granulocytes (also called polymorphonuclear leukocyte or PMN) is segmented into three to five connected lobules. The cytoplasm displays many fine (dust-like) azurophilic granules. The majority called specific granules are filled with e... | | Poja Histology Collection - Blood & Bone Marrow Subset |

Normal pleiomorph and leukemic monomorph bone marrow smear (human) | Stain: May-Grnwald-Giemsa (MGG). In normal bone marrow smear (A) a pleimorph or heterogeneous collection of different cell types (A1-7) can be identified, while in the bone marrow smear of a leukemic patient a single type dominates (in this case lymphoid cells, B-1). | | Poja Histology Collection - Blood & Bone Marrow Subset |
