Figure 3: Following 2 hours of OGD, cells died exclusively from apoptosis. Cultures were treated with either NAP (  M) or QVD-OPH (  M) and subjected to 2 h of ischemic insult. Cell viability was evaluated immediately following the ischemic period using MTS viability assay. Data was normalized to % of control. Results are shown as ; *significantly different from all other groups, (ANOVA, with post hoc Scheffe).
