The Developmental Biology Institute of Marseille (IBDM) is an international and interdisciplinary research institute oriented towards developmental biology and pathologies. The research activity is at the crossroads of development, neurobiology, cell biology, biophysics and genetics. The general theme of IBDM is to understand how the instructions encoded in the genome are translated to build structures (cells, tissues, organs) that perform specific functions, and how these processes are regulated and integrated in the whole organism. There are links between developmental biology and diseases such as cancer, neurodegenerative and genetic diseases. One of the priorities of IBDM is to foster interdisciplinarity through the integration of new and original approaches that create conceptual and technical interfaces. At IBDM, Lenne team aims at determining how (1) mechanical and (2) physical interactions are organized at cell surfaces in vivo and (3) how these interactions are processed to produce cell and tissue responses. To tackle these questions, we focus on two aspects of tissue morphogenesis, namely cell polarization and force transmission in fields of cells. We are using Drosophila and C. Elegans as systems to address questions (1-2) and
question (3), respectively. The originality of our project relies in the integration of both physics and experimental biology to study quantitatively tissue morphogenesis.
