Calcium bursting of firmly adhered HL-60 on P-selectin under wall shear stress. a Two series of typical fluorescence images of firmly adhered HL-60 cells on P-selectin at different times, and b the time-course of the normalized fluorescence intensity of the cells over the observation time. Here red and black expressed the cases with or without external force (wall shear stress) of 2 dyn/cm² on cells
