Cell viability analyses. a Cell viability was significantly decreased in a time-dependent manner in 100 μM Ald group, the group with the highest alendronate concentration (p < 0.001). After 24 h, cell viability in 100 μM Ald was significantly lower than in the other studied groups (P < 0.001). b Contrast microscope analyses demonstrated that the cell population in 100 μM Ald group was markedly more decreased than in the other studied groups. c Crystal violet stain analyses confirmed that live cells were markedly more decreased in 100 μM Ald group than in the other studied groups. d The live and dead assays showed that the population of live cells (green) was more decreased and the population of dead cells (red) was more increased in 100 μM Ald group than in the other studied groups
