title: The uptake of etiocholanolone by human bone marrow immature granulocytes.
abstract: A cell fraction enriched in immature granulocytes was obtained after fractionation of human bone marrow by a three-step procedure. This fraction sediments at an average density of 1.073 and has a high content of myelocytes and metamyelocytes. It showed the highest specific uptake of etiocholanolone when compared to other bone marrow cell fractions. Autoradiographic studies demonstrated a higher number of silver grains over myelocytes and metamyelocytes than in other cell types. These results suggest the presence in human bone marrow of a target cell for etiocholanolone, located in the late mitotic or postmitotic pool or granulocytes.
