Fig. 4.
CD34+ and CD34− ABM cells rolling on P-selectin.
Cells were subjected to wall shear rates from 487 s−1to 77 s−1 on P-selectin chimera adsorbed at 2 μg/mL on silanated glass. (A) Rolling flux. (B) Rolling velocity. (C) Rolling concentration. Each data point represents results from 3 independent experiments. Data are presented as mean ± SEM.
