Surface structure of intravasculary megakaryocytes. A scanning electron microscope study.
To elucidate the surface structure of intravasculary megakaryocytes, rabbit megakaryocytes were isolated from central venous blood and examined by scanning electron microscopy. The megakaryocytes were approximately 50 micrometers in diameter and had a spherical appearance. The surface was extremely folded with ridges and clefts, but pseudopods (budding) were never seen. Naked megakaryocyte nuclei appeared irregular in shape owing to varying amounts of residual cytoplasm often resembling buds (blebs). Their size were 15-20 micrometers.
