Fig 5. ALP activity, normalized to DNA amount of MG-63 cells cultured on 2/6, 4/11 and flat surface in basic or osteogenic medium for up to 21 days.

Fig 5

The effect of topography on the ALP activity was mild, with cells cultured in OM on 4/11 showing a significantly lower activity as compared to the flat control at 14 days, and to both the flat control and 2/6 at 21 days. Statistically significant differences are marked with * for p < 0.05 and **for p < 0.01.
