Effect of CSE on caspase 3 activity in rat periodontal ligament fibroblasts. Fluorometric assay to assess the activity of caspase-3 in rat periodontal ligament fibroblasts exposed to different concentrations of CSE (5%, 10% or 15%) (v/v) for 60 minutes in 37°C incubator. Cells not exposed to CSE were considered as controls. Each bar represents the mean ± SEM of three experiments of 16 samples in each. No significant differences were noted.
