Figure 7. Quantification of the cell migration and alignment measurements.

(a) Schematic representation of the angle to calculate directedness and orientation. (b) Directedness of cell migration in a rectangular channel and circular inserts with and without EF stimulation. (c) Cell orientation in a rectangular channel and circular inserts with and without EF stimulation. Four asterisks indicate p < 0.0001 from Dunn’s post-hoc test.
