The effect of sodium iodate on angiogenic factor expression in RPE cells.
The expression of 9 human angiogenic factors was determined by a multiplex ELISA array. (A) The image and topography of the human angiogenic factor multiplex ELISA array. Top (from left to right): ANG-2, FGF-2 and HGF; Middle (from left to right): PDGF, IL-8, TIMP-1 and TIMP-2; Bottom (from left to right): TNFα, VEGF and reference spot. (B) Quantification of the expression of the 9 human angiogenic factors according to the standard curves for each factor. The relative expression levels were compared to that of the control group. ‘**’p < 0.01; ‘***’p < 0.001.
