Figure 2: C5a does not affect cell death in endothelial cells after oxygen-glucose deprivation. b.End. 3 cells were exposed to 4 h oxygen-glucose deprivation with and without added C5a. Cell death was assessed 24 h later by trypan blue staining and compared to uninjured controls. C5a concentrations of 10–100 nM (added C5a denoted in the X-axis labels) failed to affect the extent of oxygen-glucose deprivation-induced cell death. OGD: Oxygen-glucose deprivation, Con: Controls
