Figure 3.

(a) Cell counts (n = 9–18), (b) number of trypan blue-negative cells (n = 9–18), and (c) XTT metabolization (n = 18–36 biological replicates) of L929 fibroblasts following exposure to procalcitonin for 2 × 72 h in concentrations as indicated. EtOH ethanol 20%. n = 18–28 biological replicates; ^∗P < 0.05, ^∗∗P < 0.01, and ^∗∗∗P < 0.001 versus ctrl; ^#P < 0.05 versus as indicated. Significance between concentrations is only indicated if differences between consecutive concentrations employed reach statistical significance.
