Figure 2: (a) Histograms of orientation angles of CHO cells (n = 150) on grooved polyester films (left panel) or on adjacent unpatterned control areas (right panel) one day post seeding. (b) Orientation angles of rat myoblasts (n = 100). Curves represent probability density functions of half-normal distributions fitted to the data sets. Inlet values represent average orientation angles.
