Marrow film. Giant cell with multiple nuclear lobes stained a deep blue to purple. Cytoplasm contains platelet fields with the platelet granules staining blue to purple color. A characteristic clear gray zone encircles the cytoplasmic periphery. +++ V.E.002 Megakaryocyte, Mature & Immature ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.002 Megakaryocyte, mature and immature. Marrow film. On the left, megakaryocyte with multiple nuclear lobes stained a deep blue to purple. Cytoplasm contains platelet fields staining pinkish-purple. On the right is a stage 1 megakaryoblast with a thin rim of basophilic cytoplasm and a round or horseshoe-shaped nucleus occupying most of the cell. +++ V.E.003 Megakaryocyte, Immature ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.003 Megakaryocyte, Immature (stage 1). Marrow film. A stage 1 megakaryoblast with a thin rim of basophilic cytoplasm and a round large nucleus. +++ V.E.004 Megakaryocyte, Immature ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.004 Megakaryocyte, Immature (stage 2). Marrow film. A stage 2 megakaryoblast (promegakaryocyte) with minimal cytoplasm and multiple nuclear lobes (probably four nuclear lobes). +++ V.E.005 Megakaryocyte ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.005 Megakaryocyte. Marrow film. Giant cell with multiple nuclear lobes stained a deep blue to purple. Cytoplasm contains platelet fields with the platelet granules staining blue to purple color. A characteristic clear gray zone encircles the cytoplasmic periphery. +++ V.E.006 Megakaryocyte ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.006 Megakaryocyte. Marrow film. Giant cell with multiple nuclear lobes stained a deep blue to purple. Cytoplasm contains platelet fields with the platelet granules staining blue to purple color. +++ V.E.007 Megakaryocyte ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.007 Megakaryocyte. Marrow film. Giant cell with multiple nuclear lobes stained a deep blue to purple. Cytoplasm staining blue to purple color. Note cytoplasmic pseudopodia projecting from periphery, suggesting the cell was caught in the process of proplatelet release. +++ V.E.008 Megakaryocyte ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.008 Megakaryocyte. Marrow film. Giant cell with multiple nuclear lobes stained a deep blue to purple. Cytoplasm contains platelet fields with the platelet granules staining blue to purple color. +++ V.E.009 Megakaryocyte ++ Graphic Jump LocationView Full Size||Download Slide (.ppt) V.E.009 Megakaryocyte. Marrow Biopsy. Characteristic appearance of megakaryocytes in marrow section. Two megakaryocytes are present. In one the section plane is through the nucleus (horizontal arrow). In the other, the plane is above or below the nucleus and transects the cytoplasm (vertical arrow)....
