Fig. 7. Effect of 14,15-EEZE on tube formation under hypoxic conditions. Human endothelial cells were cultured in the absence or presence of 14,15-EEZE (EEZE, 10 µmol/l) under either normoxic or hypoxic conditions for 14 hours before branching points were counted. The bar graph summarizes the results of four independent experiments; **P<0.01 vs the level in solvent-treated cells (Sol) maintained in normoxia.
