Nd step is motion classification making use of the Squigglymorph module. This module finds and displays regions of protrusion and retraction making use of pairwise comparisons of cell boundary points at instances t and tT, exactly where T is a userdefined time lag. The distribution of protruding boundary points is visualized by mapping the cell boundary to a circle, and boundary movements are quantified employing the polarization vector, based on the equation p = px ,py p 0 =@ Z2 l os a,0Z1 l in aA,dynamic behavior on the cell is visualized as a trajectory moves by way of phase space. The parameters Pcr and Rcr were adjusted to achieve superior correspondence amongst the visually observed behavior and output from the analysis. For the analyses presented here the values of Pcr and Rcr were taken to be 0.28 and 0.005, respectively. The analysis results for individual cells (n 55 for each and every construct) have been then used to carry out statistical evaluation.55685-58-0 Chemical name Extra capabilities of Squigglymorph include things like: (i) construction of smoothed curves for the parameters P(t) and R(t) applying a userdefined smoothing window, and (ii) calculation from the meansquared displacement (MSD) of the centroids and fitting the resulting curve to a persistent random walk to compute an estimate for the centroid speed and persistence (47, 48): i h MSD = two = 2S2 P t P 1 et=P : The directional persistence time P was obtained by MSD evaluation of timelapse motion pictures of over 180 min in length. Antibodies and reagents, cell culture, immunoprecipitation and kinase assays, cloning procedures, and focal adhesion imaging are described in SI Components and Techniques. ACKNOWLEDGMENTS.
