+ | **Abstract :** \\ | ||
+ | |||
+ | Development, homeostasis and regeneration of tissues result from a | ||
+ | complex combination of genetics and mechanics. Our model system is the | ||
+ | Drosophila metamorphosis, during which the fly strikingly changes, | ||
+ | within a few days, from a rather simple maggot shape to a refined | ||
+ | adult shape with wings, legs, antennas, waist, neck, and compound eye. | ||
+ | |||
+ | Tremendous progress in experimental techniques now provide access to | ||
+ | quantitative cell-scale information within tissues, whether on the | ||
+ | cell shapes and shape changes, on cell-cell interaction forces, and on | ||
+ | the genes being expressed. To uncover mechanisms governing tissue | ||
+ | development, a rigorous multiscale approach is required. | ||
+ | |||
+ | The biologist and physicist jointly address several challenges : | ||
+ | linking cell-cell interactions with tissue structure; linking | ||
+ | cell-level dynamical processes such as cell divisions, deaths and | ||
+ | rearrangements, with tissue-level morphogenetical changes; and most | ||
+ | important, understanding the interplay between genetics and mechanics, | ||
+ | which both contribute to regulate the morphogenesis. | ||
