Bone tissue growth depends on the local curvature of the substrate. A simple mathematical model predicts the observations of in vitro tissue growth inside convex and non-convex pores. Experiments show that tissue growth rates can be doubled by changing the geometry of a prismatic pore from square to cross-like. Methods based on these observations are proposed to optimize the design of porous scaffolds.
