We examined various murine hematopoietic cell populations for their capacity to interact with radiolabeled histamine. Only bone marrow cells (BMC) retained substantial amounts of radioactivity, in contrast to thymus, spleen, and peritoneal cells. The characteristics of this interaction are consistent with histamine uptake rather than receptor binding. Indeed, this process is temperature and sodium dependent and reduced by various metabolic inhibitors. Furthermore, the effect of antagonists or agonists of the H1, H2, and H3 receptor subtypes is not in accordance with the involvement of either of these receptors in histamine binding. The target cells of histamine copurify with hematopoietic progenitors in the low-density BM population. They are most enriched in the subset sorted from the blast cell window on the basis of high rhodamine retention. This fraction contains on the average 80% to 90% immature cells and is highly enriched for several clonogenic progenitor subsets. Sixty percent of the Rh-bright cells are labeled by 3H-histamine, as assessed by autoradiography, suggesting that a variety of immature cells participates in this phenomenon. Furthermore, in all sorting procedures used here, the cells capable of histamine uptake coenrich with those producing histamine in response to interleukin-3, indicating at least a partial identity between these cells.
