Figure 7: Effects of PEDF proteins on viability of T24, 231-BR, and 4T1-BR5 cells in culture: effect of PEDF on cell viability at the treatment end point. Plot of relative cell numbers quantified based on intracellular ATP content (shown on the left) and mitochondrial dehydrogenase activity (shown on the right) as biomarkers of live cells. Cell viability was expressed as percentage of luminescence values relative to untreated controls, and percentage of absorbance at 490 nm relative to untreated controls, respectively. Each point is the average of triplicate assays. Error bars indicate average ± SD.
