摘要

Stem cells cultured on a complex micronano-rough Ti6Al4V surfaces increased osteoblastic markers and produced an osteogenic microenvironment. Additionally. MSCs reduced inflammatory interleukins. suggesting that surface topography modulates the inflammatory microenvironment. PEEK surfaces increased pro-inflammatory interleukin production and yielded lower levels of osteogenic differentiation in comparison to microano modified Ti6Al4V. These surfaces also increased inflammatory cytokines that favor formation of fibrous tissue. Taken together our results may translate to more and faster peri-implant bone formation on MMN Ti6Al4V in vivo, leading to earlier stability of the bone-implant construct.
