Figure 2. FACS profiles of the distribution of G₀, G₁, and S/G₂/M cells in different lin^– populations.

(A) Representative FACS contour plot for 14.5-dpc Ter119^– FL cells after staining with Hst and Py and for Ki67. (B) Representative FACS contour plot for lin^– 3-wk BM cells after staining with Hst and Py; sorted G₀ cells after staining for Ki67 (>90% of the G₀ cells showed no Ki67 expression); and sorted G₁/S/G₂/M cells after staining for Ki67 (>99% of the G₁/S/G₂/M cells expressed Ki67). (C) Representative FACS contour plots for lin^– 4- and 10-wk BM cells after staining with Hst and Py. Percentages indicate the proportion of total cells found within the indicated gene.
