Figure 6.

Cell viability of U-87 and human HF cell (A and B, respectively) was assessed by MTT assay after 24, 48 and 72 h of exposure. Data from LDH release assay at 24, 48 and 72 h exposure times were in panels C (U-87 cells) and D (HF cells). Values are the mean ± SE of two independent experiments performed in triplicate. *p < 0.05 vs. untreated cells. (E) Representative images from colony forming efficiency of U-87 cells grown in presence of LnHS or vehicle control for ten days; the experiment was performed in duplicate.
