Purification of Sca-1+Lin− BM cells. Cells in the different cell fractions obtained by MACS purification (see Materials and Methods) were analyzed by FACS for the presence of Sca-1+Lin+, Sca-1+Lin−, and Sca-1−Lin+ cells. Nonspecific staining was determined by FITC- and PE-conjugated isotype control antibodies. Percentage of each subpopulation is shown in the appropriate area of the dot plot.
