Tissue engineering using mechanobiology and robotic micromanipulationA team of EPFL engineers has discovered a strategy to shape living tissues like dough. Have you ever wondered how a sphere of cells, morula, gives rise to tissues and organs with mesmerizing shapes and architectures? The secret lies in the mechanics of embryonic tissues. They exhibit a viscous (fluid-like) and an elastic (solid-like) behavior depending on the forces acting on them.
