Shaping active matter through topological defects

Karsten Kruse Biochemistry Department Université de Genève, Switzerland

Abstract : During their development, organisms experience a number of morphogenetic events. Often, they involve the formation of invaginations or protrusions. From a physics point of view, biological tissues are active materials, in which chemical energy is converted into mechanical work. This is achieved by the cytoskeleton, a network of filamentous proteins that can exhibit large scale orientational order. The activity of cytoskeletal proteins can generate mechanical stress eventually driving developmental tissue shape changes. It remains largely unknown how stress is organised to achieve these transformations. Recently, it has been argued that topological defect in the orientational order could play an important role in this context. Here, I will discuss several aspects of topological defects in active matter and how their presence is connected with the formation of protrusions.
