Quantification of cellular motility. (a) Turning frequency of MTLn3 MenaInv cells in the presence of EGF-loaded device (b) Directionality of the same cells. (c) The chemotaxis index and (d) the effective chemotactic index (directionality * chemotaxis index) of the cells in the EGF gradient generated by the NANIVID. [Error bars represent ± standard deviation from three experiments, 10 to 25 cells in each experiment. Statistical significance from the control is indicated by the line with star on the top (p < 0.05)].
