DESCRIPTION:The mechanical properties of living tissues are la
 rgely controlled by networks of fibres\, inside th
 e cells (cytoskeleton) as well as in the extra-cel
 lular matrix (mostly collagen based). In this talk
 \, I will illustrate the behaviour of these materi
 als using two experimental systems. The first one 
 is a model system\, made of large macroscopic fibr
 es entangled to form of light felt. It provides a 
 convenient material to probe the mechanical behavi
 our of random networks. The second study is perfor
 med on in vitro collagen gels. Using either living
  cells or external mechanical components\, we show
  that a local stretch induces both a strong fibre 
 alignment and a large increase of the fibre densit
 y: this response is found to be a non-linear elast
 ic effect. \n\n
