title: Small megakaryocytes--an identification problem.
abstract: The number of bone marrow megakaryocytes (MK) was estimated in May Grunwald-Giemsa-stained (MGG) and immunoenzymatically stained smears. The latter was performed after incubation with a monoclonal antibody (ITI-PL1) directed against blood platelets and megakaryocytes (MK). The MK were grouped according to their size (diameter above or below 30 micron, respectively). Altogether 7.9% more MK were recognized in ITI-PL1 stained smears as compared to MGG-stained smears, mainly because comparatively few small MK were recognized in MGG-stained smears.
