AbstractIn fast moving cells such as amoeba and immune cells, spatio-temporal regulation of dendritic actin filaments shapes large-scale plasma membrane protrusions. Despite the importance in migration as well as in particle and liquid ingestion, how these processes are affected by the micrometer-scale surface features is poorly understood. Here, through quantitative imaging analysis of Dictyostelium on micro-fabricated surfaces, we show that there is a distinct mode of topographically guided cell migration ‘phagotaxis’ directed by the macropinocytic Ras/PI3K signaling patches. The topography guidance was PI3K-dependent and involved nucleation of a patch at the convex curved surface and confinement at the concave surface. Due to the topography-dependence, constitutive cup formation for liquid uptake in the axenic strain is also destined to trace large surface features. Given the fact that PI3K-dependency of phagocytosis are restricted to large particles in both Dictyostelium and immune cells, topography-dependency and the dual-use of membrane cups may be wide-spread.

Because they can achieve a high degree of molecular chain alignment in comparison with their bulk counterparts, the mechanical and thermal properties of polymer nanofibers are of great interest. However, due to their nanometer-scale size, it is difficult to manipulate, grip, and test these fibers. Here, we demonstrate simple repeatable methods to transfer as-drawn fibers to micrometer-scale test platforms where their properties can be directly measured. Issues encountered and methods to minimize measurement artifacts are also discussed.
