Figure 8

In vitro study1. (a) MC3T3-E1 cell (blue) attachment on each substrate after the 24 h incubation, observed using SEM. (a2, 3) and (a5, 6) are magnifications of (a1) and (a4), respectively. (b) The motion of stained cells on CPEEK, calculated with time-lapse imaging. This shows the motion with respect to the cells’ first position (X = 0, Y = 0) on the XY coordinate. The red dots indicate their final point at 24 h. (c) The plot depicting the XY coordinates for the motion of stained cells on CPEEK-AN. (d) The XY coordinates for four cells that moved beyond the XY coordinates of the plot in (c). (e) Quantification of the CCK-8 assay (absorbance at 450 nm). (f) The plot depicting cell numbers (manual counting).
