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 against shear stress. The plot illustrates the time-course (a), activation ratio (b), peak intensity (c) and delay time (d) for calcium signaling of firmly adhered HL-60 on substrate coated with 10 μg/mL P-selectin under shear stresses of 0.0, 0.2, 0.6 and 2 dyn/cm2. The data represent the mean plus SEM from at least 20 cells in three experiments. Each inset in b, c or d presents the calcium signaling of HL-60 on blank substrates under shear stresses of 0 and 2 dyn/cm2. The significant level of difference from blank substrate group was shown by p value, * for p < 0.05 and ** for p < 0.01
