Fold change in gene expression of bone formation markers (normalized to GAPDH) over TCP control (calibrator =1) in osteoblast-like cells cultured on Ti-PEEK and PEEK surfaces.
Notes: *95% CIs of mean fold change values of Ti-PEEK and PEEK do not overlap.
Abbreviations: BMP, bone morphogenetic protein; GAPDH, glyceraldehyde 3-phosphate dehydrogenase; PEEK, polyetheretherketone; Ti-PEEK, titanium-coated PEEK; TCP, tissue culture plastic.
