Analysis of cell viability and proliferation for the modified surfaces including the bare coatings of benzoyl-PPX and maleimide-PPX, and the modification of immobilized CHX, BMP-2, and RGDACC surfaces. (a) Fluorescence micrographs of the cultured 3T3 fibroblasts on the studied surfaces after 24 and 120 hours. (b) Statistical analysis of the 3T3 fibroblasts viability by the MTT assay on the surfaces after 24 and 120 hours. (c) Fluorescence micrographs of the cultured MΦs on the studied surfaces after 24 and 120 hours. (d) Statistical analysis of the MΦs viability by the MTT assay on the surfaces after 24 and 120 hours. Each bar in (b,d) represented the mean values (±SD) of three independent experiments.
