ITGAM and acute promyelocytic leukemia: Mechano-NPS analysis of ATRA-treated APL cells sorted for CD11b expression showed that both CD11b+ AP-1060 and NB4 cells were far more deformable than CD11b- AP1060 cells (p < 0.0001) (Figure S2D) and that only for AP-1060 did CD11b+ cells recover significantly faster than their CD11b- counterparts (p < 0.0001) (Figure S2E).
