Bone Anabolic Effects of Soluble Si: In Vitro Studies with Human Mesenchymal Stem Cells and CD14+ Osteoclast Precursors

Figure 3

Effects of Si on cell density, apoptosis, and morphology of CD14+ cell cultures. (a) Cellular density, determined by total DNA content; (b) apoptosis, determined by caspase-3 activity; (c) actin staining and visualization under confocal laser scanning microscopy. Significantly different than the control. White bars represent 150 μm.
