DESCRIPTION:The mechanical properties of tissues play an important role fo
 r their growth and even in some circumstances for gene expression.\nThey a
 re particularly important for cancerous tissues and tissues during early d
 evelopment. I will show in this talk that at a macrocopic scales\, tissues
  can be considered as visco-elastic fluids and show some effects associate
 d to their activity such as spontaneous flows and active turbulence. \nA m
 ore microscopic study at the cell scale based on the so-called&nbsp\; vert
 ex model shows that under strong deformations\, tissues ate thixothropic f
 luids and that at long times\, they are shear thinning fluids. As also sho
 wn by existing numerical simulations\, tissues formed by dividing cells do
  not have a finite yield stress.
