From: Mechanical regulation of calcium signaling of HL-60 on P-selectin under flow
Variation of activation ratio, peak intensity and delay time for calcium signaling of firmly adhered HL-60 under shear stress of 2 dyn/cm2 versus immobilized P-selectin concentration. a The time-course, b the activation ratio, c the peak intensity and d the delay time of calcium signaling with different of immobilized P-selectin concentrations under wall shear stress of 2 dyn/cm2. The data represent the mean plus SEM from at least 20 cells in three experiments. The significant level of difference from blank substrate group was shown by p value, * for p < 0.05 and ** for p < 0.01
