Expression of β-galactosidase in SCL^lacZ/w bone marrow cells. (A) Representative FACS profiles of forward scatter plotted against β-galactosidase activity (measured as fluorescence) for FACS-Gal-labeled bone marrow cells from SCL^lacZ/w and SCL^w/w mice. Gating windows and the percentage of cells in each window are shown for lacZ^neg, lacZ^int, and lacZ^high fractions. (B) May-Grünwald-Giemsa stained cytocentrifuge preparations of unsorted and sorted bone marrow fractions from SCL^lacZ/w mice.
