Figure 4: Effects of udenafi l on the survival and growth of VEC and VSMC. (a) VEC proliferation was signifi cantly less inhibited by 100 μmol/l udenafi l than VSMC. (b) VEC apoptosis was signifi cantly less induced by 100 μmol/l udenafi l than VSMC. (C-E) VEC viability was signifi cantly less inhibited by 100 μmol/l udenafi l than VSMC. (c) Cell viability measured by MTT assays. (d) Cell viability measured by manual cell counting and trypan blue staining. (e) Cell viability determined by fl ow cytometry. Data are means standard deviation (SD). *P < 0.05 vs corresponding VSMC group. BrdU = 5-bromo-2'-deoxyuridine, MTT = methylthiazoletetrazolium
