Figure Lengend Snippet: The impact of nanoscale modification of PEEK implant surfaces on the mechanical perception, proliferation, and expression of fibrosis-related proteins in L929 cells. (A) The expression levels of mechanical perception, proliferation, and fibrosis-related proteins were evaluated in L929 cells cultured on different nanoscale modified PEEK surfaces at multiple time points. (B) The secretion of TGF-β1 from L929 cells cultured on various nanoparticle-modified PEEK surfaces was quantified using Elisa at multiple time points. (C) Immunofluorescence analysis was conducted to assess the expression differences of Piezo1, ITGB1, and α-SMA in L929 cells cultured on different nanoparticle-modified PEEK surfaces. (D) Quantitative fluorescence analysis was performed on the data presented in C.
