Analysis of directional cell migration behaviors. (a) Probability of MC3T3-E1 cells migrating along tips of 10 nm thick TiOx arrowheads with arrowhead arms of 10, 20, 35, and 60 μm in length. The probability was calculated as percentage of cells that migrated along arrowhead tips out of total number of cells that migrated on patterned surface. (b) Average migration speed of MC3T3-E1 cells on patterned TiOx arrowheads with arrowhead arms of 10, 20, 35, and 60 μm in length. (c) Aspect ratio of MC3T3-E1 cells on different platforms. Aspect ratio was calculated as ratio of cell’s major axis to its minor axis. Numbers in box charts indicate mean values and lines indicate median values. Statistical analysis was performed using one-way ANOVA followed by Tukey’s post hoc test, with **p < 0.01, ***p < 0.001, and NS – not significant
