Regulation of cellular responses to macroporous inorganic films prepared by the inverse-opal method

▶ Macroporous film can potentially control the morphology of MC3T3-E1 cells. ▶ Pore size and the composition of the scaffolding affects cell proliferation. ▶ Cell proliferation was restricted by macroporous silica with 100-500 pore sizes. ▶ In case of macroporous HAp films, the number of growing cells steadily increased.
