There is an apparent paradox in biology: the intrinsic elasticity of tissues should counteract the mechanical forces that help organs form. What is more, permanent deformation can only be observed if there is a mechanism that blocks the cellular forms in their transient states. Researchers at the Laboratoire de biologie du développement (CNRS / Sorbonne Université / Inserm) led by Michel Labouesse have now succeeded in identifying such a mechanism and have determined the cellular micromechanics behind it. Their work is published in Nature.
