The surface topography of a material can influence osteoclast ***,the surface structural factors that promote osteoclast activity have not yet been investigated in ***,we investigated osteoclastogenesis by testing various defined patterns with different dimensions and *** systematic patterns,made of a cyclo-olefin polymer,were prepared at a micron-,submicron-,and nano-scale with a groove,hole,or pillar shape with a 1:1 pitch ***264.7 cells were cultured on these patterns in the presence of the receptor activator of NF-κB ligand(RANKL).Osteoclast formation was induced in the order:pillar>groove≥*** two-dimensional factors also indicated that submicron-sized patterns strongly induced osteoclast *** optimal pillar dimension for osteoclast formation was 500 nm in diameter and 2μm in ***,we observed two types of characteristic actin structure,i.e.,belt-like structures with small hollow circles and isolated ring-like structures,which formed on or around the pillars depending on size and ***,resorption pits were observed mainly on the top of calcium phosphate-coated ***,osteoclasts prefer convex shapes,such as pillars for differentiation and *** results indicate that osteoclastogenesis can be controlled by designing surfaces with specific morphologies.
