Figure 9. Effects of exogenous C9 protein on the viability of cultured human RPE cells. The cells were stimulated with a hyperosmotic medium (+ 100 mM NaCl) or an isosmotic medium containing CoCl₂ (150 µM) for 6 h and 24 h in the absence and presence of C9 protein (10 nM), respectively. The numbers of independent experiments using cell lines from different donors are indicated in the bars. Significant difference versus unstimulated control: *p<0.05. Significant difference versus NaCl control: ●p<0.05.
