From: Network organisation and the dynamics of tubules in the endoplasmic reticulum
Tracked contours of ER tubules show indications of active motion. (a,c) Contours are overlaid to show the time-dependence of tubule shape (inset shows fluorescence image of tracked tubule). More frequently occupied positions are coloured in yellow. (b,d) Mean position of tubules in (a) and (c) respectively, coloured according to the variance of transverse oscillations. Arrows show direction and magnitude of significant transverse skewness, if detected.
