Flow cytometric analysis and MS-based CSC analysis of CD protein abundance changes in AML cells after ATRA stimulation. (A) Representative flow cytometric analysis of CD proteins in unstimulated (blue line) and ATRA stimulated (red line) AML cells. Unstimulated and ATRA stimulated control AML cells are shown in plain dark gray and light gray, respectively. (B) Results of the flow cytometric analysis are shown as the average log₂ ratios of the geometric mean FI signals of ATRA stimulated to unstimulated AML cells (n = 3). Error bars represent SDs. (C) Results of the MS-based CSC analysis are shown as the average log₂ protein ratios of ATRA stimulated to unstimulated AML cells (n = 3). Error bars represent SDs.
