Events inside living cells are regulated by asters of dynamic polymers called microtubules. These asters have remarkable abilities to self-organize and to find the center of the cell, which has important biological implications. I will explain experiments with fragments of fish melanophore cells that allow to visualize these self-organization and centering phenomena and present mathematical (integro-PDE) model and computer simulations that shed light on the molecular mechanisms behind asters' behavior.
