The environment of living cells is made of a complex 3D fibrous structure with unique mechanical properties. These properties - combined with the ability of cells to generate, sense and respond to forces- create a novel mechano-biological system that direct cells toward defined fates and organization. Our group strives to understand how mechanical forces regulate biological processes at the cell and tissue level. In our experiments, we embed cells in 3D hydrogels of various types and form and use live confocal microscopy for studying cell behavior in environments that mimic tissue structures. We use traction force microscopy, image analysis and finite element computer simulations to quantify and understand the mechanical interaction between cells and their environment. Our research provides mechanical tools to direct, control and manipulate cell behavior including organization of cells toward defined tissue structures, differentiation of stem cells, and regulation of disease states..
