(A) Inhibition of endothelial cell proliferation in vitro. HMEC-1 (Left) and C6 cells (Right) were infected with AdK3 (⋄) or AdCO1 (□) at a moi ranging from 10 to 700 pfu/cell. The cells that survived to AdK3 or AdCO1 infection were quantified after 4 days by an MTT test (see Material and Methods). (B) Sensitivity of HMEC-1 and C6 cells to ionizing radiations in vitro. HMEC-1 (Left) and C6 cells (Right). Cells were irradiated at a dose ranging from 1 to 7.5 Gy, and cell survival was assessed after 9 days. Non-irradiated cells were included in each culture plate as controls.
