(a, f) Ti, (b, g) Ti/DOPA, (c, h) Ti/DOPA/SA, (d, i) Ti/DOPA/SA/Sr1, and (e, j) Ti/DOPA/SA/Sr5 ((a–e: magnified 40 times); (f–j: magnified 100 times)). (k) Cell proliferation measured by counting under a fluorescence microscope after 1, 3, and 7 days of incubation. (l) ALP activity of MG63 cells after 3, 7, and 14 days of incubation.
