The most commonly used source of MSC's is bone marrow aspirate. Most of the adult bone marrow consists of blood cells in various stages of differentiation. [10] These marrow components can be divided into plasma, red blood cells, platelets, and nucleated cells. The adult stem cell fraction is present in the nucleated cells of the marrow.
Bone marrow aspirate smear: visceral leishmaniasis Leishmaniasis is diagnosed in the hematology laboratory by direct visualization of the amastigotes (Leishman–Donovan bodies). Buffy-coat preparations of peripheral blood or aspirates from marrow, spleen, lymph nodes, or skin lesions should be spread on a slide to make a thin smear and stained ...

A Wright's-stained bone marrow aspirate smear from a patient with leukemia. Bone marrow examination is the pathologic analysis of samples of bone marrow obtained via biopsy and bone marrow aspiration.

Bone marrow aspirate: ring sideroblasts. Ringed sideroblasts are seen in the bone marrow. On the peripheral blood smear can be found erythrocytes with basophilic stippling (cytoplasmic granules of RNA precipitates) and Pappenheimer bodies (cytoplasmic granules of iron). [13] The anemia is moderate to severe and dimorphic.
Pancytopenia usually requires a bone marrow biopsy in order to distinguish among different causes. [5] anemia: hemoglobin < 13.5 g/dL (male) or < 12 g/dL (female). leukopenia: total white cell count < 4.0 x 10 9 /L. Decrease in all types of white blood cells (revealed by doing a differential count). thrombocytopenia: platelet count < 150×10 9 /L.
Bone marrow – is a semi-solid tissue which may be found within the spongy or cancellous portions of bones. [75] Bone marrow is the primary site of new blood cell production or hematopoiesis. [76] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
