Physical control of cell shape and cell polarity

Nicolas MINC Department of Microbiology, Columbia University, New York, USA Invité par Joseph ZYSS (IFR)
Cell polarity, the process by which cells choose where to grow, move or divide, is fundamental to the function of most organized biological processes and is the basis of morphogenesis in living organisms. Using model organisms ranging from fission yeast to Sea Urchin embryos I will present different novel biophysical approaches for studying and controlling cell polarization. Using microfabricated devices, to impose controlled shape to these cells I will present a study on the relations between cell shape and internal organization. I will show how these chambers can be adapted to measure important mechanical properties of living cells. I will finally present how external electric fields can direct and control cell polarity.
