Cytochemical procedures were used to identify and quantitate granulocyte and macrophage precursors from mouse bone marrow cells in plasma clot cultures. Excellent clonal morphology and cellular enzyme activity were obtained when using plasma clots as the support matrix and buffered formalin acetone as the fixative. For cytochemical identification, naphthol AS acetate esterase staining was used for macrophages and peroxidase for granulocytes. These enzyme properties were confirmed by inactivation studies with a variety of inhibitors, group specific chemical modifications, and pinocytotic affinity for horseradish peroxidase. When mouse bone marrow cells (3 X 10(4) cells/dish) were cultured in plasma clots with human placental or L-cell-conditioned medium, 70 to 110 colonies were produced. Both pure granulocyte (CFU-g) and pure macrophage colonies (CFU-m) were observed, but approximately 5% of the total colony number was composed of mixed granulocyte/macrophage colonies (CFU-gm). The number of plated cells correlated strongly with the colony number (0.990 less than r less than 0.999).
