Engineering cell shape
Cellular shape is a fundamental signal for proliferation, potently regulates cell growth and physiology, and is indicative of specific functions. Membrane protrusions influence cell shape and are highly relevant for adhesion, migration, and rigidity sensing. Specific cell shapes also determine the direction, in which a dividing cell spatially places its daughter cell.
In our ongoing work, we are engineering specific cell shapes using microcontact printing (μCP) and custom-designed adhesive micro-patterned surfaces to better understand how musculoskeletal tissue architecture is lost during degenerative processes such as seen in osteoarthritis.
Controlling cellular shape will likely play an important role in understanding and engineering biomaterials with cell shape-instructive properties for future applications in regenerative medicine.
