Migrational responsiveness to blood HPC assessed by intracellular F/G actin ratio following incubation with predetermined optimal dose of (a) SDF-1α (10 ng/mL), (b) HGF (50 ng/mL), or (c) VEGF (50 ng/mL) at varying time-points. Summary F/G actin ratio data are presented in (d) following 30 seconds of stimulation. Data are presented as mean ± SEM (); between group comparisons and within group comparisons to diluent control.
