Flow cytometric analysis of hematopoietic cells derived from methylcellulose colony assay of H1/S17 cells. Cells were washed free of methylcellulose before incubation with indicated antibodies and analyzed by two-color (Upper) or one-color (Lower) flow cytometry. (Upper) Isotype controls are shown (Left), and percent positive cells in each quadrant is indicated. (Lower) Isotype control is demonstrated by line, and indicated antibody is demonstrated by filled plot. Percent positive cells are shown by labeled marker.
