Representative scatter plot with two parameters (ABCG2 positivity versus N/C ratio) indicating that the stem cells in the upper right (UR) quadrant were strongly positive for ABCG2 and had high N/C ratio. UL: upper left, LL: lower left; LR: lower right. Each red diamond represents a cell. Dark blue circle denotes that the cell was p75 positive. Cells with no circle were negative for p75. All the cells in the UR quadrant were positive for p75
