Micropatterning in Cell Biology, Part C

Matthieu Piel and his team develop microfabricated and microfluidic tools to quantitatively control the physical parameters of the cell’s environment and study how cells grow, divide and migrate. The team focused on how physical confinement, geometry and forces affect cell division and cell migration. The general aim of these studies is to draw a line between the physics of the active matter cells are made of and the behavior of cells in the complex environment of tissues, in the context of the immune response and tumor development.
