Teams from CNRS, the Université de Strasbourg and Inserm, led by Daniel Riveline [1], Jean - Marie Lehn [2] and Marie - France Carlier [3], have synthesized molecules capable of causing rapid growth
of actin networks, one of the components of the cytoskeleton.
In addition, they have identified the growth mechanism
of the actin network by comparative in vivo and in vitro studies in order to ensure the validity of the process.

actin dynamics is key in their formation and movement.
Actin is a filamentous protein, which together with other cytoskeletal elements forms a dynamic
network of filaments that provide both structural support, as well as critical functional capabilities, to the cell.
Actin allows vital actions to be performed by assembling and disassembling itself spontaneously, continually and rapidly in the form
of filaments that organize themselves and form
networks of parallel bundles or intertwined meshes (known as lamellar
networks).
Szymanski and his fellow researchers found that
