Figure 3.

Alkaline phosphatase (ALP) activity of osteoinductive fibronectin (oFN, 5 μg·mL⁻¹) on MC3T3-E1 cells, at 3 and 10 days. Cells were seeded at a density of 1 × 10³ cells/well on plates coated with integrin-binding fibronectin (iFN) or oFN and incubated. Non-treated cells were used as control. ALP activity was normalized versus control and is represented as mean ± standard deviation (n = 3). * p < 0.05 compared with iFN-loaded groups or control.
