Shear Stress Triggers Angiogenesis of Late Endothelial Progenitor Cells via the PTEN/Akt/GTPCH/BH4 Pathway

Figure 2

The effect of LSS on in vitro function of late EPCs at different time points. (a) Quantification analysis of VEGF-induced migration of late EPCs ( vs. EPCs at 0 h, per group). (b) Quantification analysis of proliferative activity of late EPCs ( vs. EPCs at 0 h, per group). (c) Quantification analysis and representative photograph tube information of late EPCs (represented as relative value to EPCs at 0 h, vs. EPCs at 0 h, per group). Scale bar 200 μm. Least significant difference was applied for the post hoc test in statistical analysis. hpf = high power field.
