Figure 4.
Adhesion capacity of EPCs treated with TNF-α and Tan IIA and plated onto fibronectin-coated culture dishes. TNF-α decreased EPC adhesion capacity, while Tan IIA dose-dependently increased cell adhesion. EPCs without treatment served as the control group. Data are presented as the mean ± standard deviation (n=5). $P<0.05 vs. control group; *P<0.05 vs. TNF-α group. EPCs, endothelial progenitor cells; TNF-α, tumor necrosis factor-α; Tan IIA, tanshinone IIA.
