Scanning electron microphotographs (SEM) of the geometrical configuration of the concavity assembled into the titanium bioreactors. (A,B) Macro- and microporous geometric landscapes of titania substrata later coated by highly sintered crystalline hydroxyapatite. Macro- and micro-topography of the constructed concavities (light blue arrows) within the titanium' bioreactors present surface topographies that result I the induction of bone differentiation in vivo (Ripamonti et al., 2012a, 2013). (C) A concavity (light blue arrows) prepared on the titanium' surface show nano-topographic macro- micro-porosities that are inductive of cell differentiation and the expression of the osteogenic phenotype (Ripamonti et al., 2012a, 2013).
