Abstract：
:A method is described that permits the removal of hematopoietic cells and macrophages from mouse bone marrow cultures. The method is based on the difference in effect of extracellular ATP4- ions (ATP in the absence of divalent, complexing cations) on cells of hematopoietic origin, including macrophages, and of nonhematopoietic origin, such as fibroblastlike stromal cells. In contrast to fibroblastlike cells, hematopoietic cells and macrophages form under the influence of ATP4- lesions in their plasma membranes, which allows the entrance of molecules such as ethidium bromide (EB) and potassium thiocyanate (KSCN), which normally do not easily cross the membrane. The lesions can be rapidly closed by the addition of Mg2+ to the incubation medium, leaving the EB or KSCN trapped in the cell. This method allows the selective introduction of cell-toxic substances such as KSCN into hematopoietic cells and macrophages. By using this method, fibroblastlike stromal cells can be isolated from mouse bone marrow cultures.
