[Two-dimensional size-charge distribution of bone marrow cells in children with chronic immune neutropenia]

Physical characteristics of bone marrow cells of normal donors were comparatively studied with those of children with immune neutropenia. As a result of the bone marrow cell separation in the density gradient according to their sedimentation rate, fractions enriched with cells of one histogenetic series (lymphoid, erythroid and granulocytic) were obtained. Electrophoretic mobility of immature granulocytes in normal donors differed from that in children with immune neutropenia.
