Mineral deposition assay (A) and alkaline phosphatase (ALP) activity (B) together with the expression levels of osteogenesis-related genes [(C), OCN; OPN; BMP-2] for BMMSCs seeded on the TiO2 and Cu-TiO2 coating. All experiments were performed in triplicate. Notes: ## indicates p < 0.01 vs. TiO2 group. Scale bar = 75 μm.
