Self-organisation in living matter :
from cell motility and cytokinesis to morphogenesis
• Cell motility: Ratchetaxis and Scallop Theorem
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
Synthetic polyamines trigger growth of lamellipodia within minutes (scale bar 20μm).
• Cytokinesis: myosin clusters dynamics and rings constriction across systems
Myosin clusters dynamics determine the evolutions of cytokinetic rings visualised in a single focal plane with micro-fabricated cavities (myosin, scale bar 5μm).
• Morphogenesis in vitro: collective effects in cells
Elongation of an epithelial colony results from nematic fields and topological defects (scale bar 50μm).
• Scaling and injections of fission yeast
