Endothelial microstructure. Rat mesenteric artery incubated with vehicle (DMSO 0.4 ml/L, A, B and C) or DSP (0.4 ml/L, E, F and G) for 24 hrs. Human MCA incubated with vehicle (DMSO 0.8 ml/L, D) or DSP (0.8 ml/l, H) for 12 hrs. Magnification: × 3000 for A and E; × 5000 for B, F, D and H; × 10000 for C and G. EC = endothelial cells; SMC = smooth muscle cells; EM = elastic membrane.
