Figure 3. Bacterial sphingomyelinase suppresses lens epithelial cell survival

BLEC (A) and HLEC (B) were treated with vehicle (zero concentration) or different concentrations of bSMase for 24 h. Cell viability was determined by MTT assay as described in Methods. Values expressed as percent survival of vehicle-treated controls (given as 100%). All values reflect the mean±SEM of at least three independent experiments.
