The Influence of Mg2+ Ions on the In Vitro Efficacy of Chitosan-Titanium Dioxide Nanotubes (CTNTs) Scaffolds

Figure 6

FDA-stained MG63 cells cultured on CTNTs scaffolds only and with Mg2+ ions adsorbed at different initial concentrations of MgCl2 for 3 (a-f), 5 (g-l), and 7 (m-r) days. Scaffolds and polystyrene well (positive control) were seeded with approximately 30,000 cells/well in 24-well plates. Scale bar corresponds to 100 μm.
