The release of zirconium ions from Ti–Zr alloy layers may results in the expression of osteogenic genes. Zr-30 and Zr-60 have higher ion release than Zr-90 (Fig. 2 d), therefore, the osteogenic gene expressions of rBMSCs on Zr-30 and Zr-60 are larger than that on Zr-90. Besides, the cell gene expression on Zr-90 is sometimes lower than …
