Figure 7. The cell population doubling time of MG 63 cells between days 1 and 3 (DT1–3), days 3 and 7 (DT3–7) and days 1 and 7 (DT1–7) after seeding on polystyrene culture dishes (PS) and NCD films doped with 0, 133, 1000 or 6700 ppm of boron.

Mean ± S.E.M. from 3 experiments (in total, 9 measurements for each experimental group and time interval). ANOVA, Student-Newman-Keuls Method. Statistical significance: I, II, V: p≤0.05 compared to polystyrene, undoped NCD and NCD doped with 6700 ppm of B, respectively.
