TEAM LEADER

Daniel RIVELINE

The Cell Physics team characterizes self-organization of cells, cell motion, cell division, morphogenesis of tissues in vitro and in vivo. The projects involve synergized approaches between theoretical physics, cell biology, microfabrication.

Current projects

Self-organisation in living matter : from cell motility and cytokinesis to morphogenesis

 

  • Cell motility: Ratchetaxis and Scallop Theorem

Publications.

How a cell moves from a point A to a point B in the absence of long range gradient.

 

  • Lammelipodia growth promoter: supramolecular compounds specific to actin

Publications.

Synthetic polyamines trigger growth of lamellipodia within minutes (scale bar 20μm).
 

  • Cytokinesis: myosin clusters dynamics and rings constriction across systems

Publications.

 Myosin clusters dynamics determine the evolutions of cytokinetic rings visualized in a single focal plane with micro-fabricated cavities (myosin, scale bar 5μm).

  • Morphogenesis in vitro: collective effects in cells

Publications.

Elongation of an epithelial colony results from nematic fields and topological defects (scale bar 50μm).

 

  • Scaling and injections of fission yeast

Publications.

 
Asymmetric division : Scaling arguments predict the localisation of septum correlated with differences in cell ends (left).
Fission yeast behaves as a balloon and can be injected (right, scale bar 5μm).

  • Reinforcement of focal contacts and cell-cell junctions (adherens junctions and hemidesmosomes)

Publications.
 

Adhesive contacts elongate with local forces within minutes (compare top and bottom, scale bar 5μm).
They recruit adhesion proteins while keeping their matter density constant.

A dashboard to study cell movement

Individual cells move in vivo in complex 3D environments. Their motion occurs at zero force and requires symmetry breaking. In this study at the…
