Abstract
The geometry of polymeric matrices is a powerful tool to control cell behavior. On page 1991 N. Ma, A. Lendlein, and co-workers demonstrate human adipose-derived stem cells that show ROCK pathway-mediated differences in their response to square- and round-shaped microwells with respect to their morphology, proliferation, migration, and differentiation. Phagocytes react differently to spherical and ellipsoid microparticles, which now can shift their shape upon stimulation due to an internal polymer micronetwork structure.
