An increasing number of studies highlight the importance of signaling localization. We developed methods to perturb this localization using magnetic nanoparticles. Proteins of interest are grafted on magnetic nanoparticles, allowing to magnetically localize them. We first propose a new method to engineer directly a spatial gradient of signaling protein concentration within in cell extract droplets using super-paramagnetic nanoparticles. We observed a link between a spatial asymmetry in biochemical cues and microtubules aster positional information. Our assay provides a bottom-up approach to examine the minimum ingredients generating polarization and symmetry breaking within cells. We then examined the possibility to magnetically perturb en...
