Effect of poly(DMA-MEA) on cell viability of human gingival fibroblast cells HGF-1 after 24 h incubation. The cells were cultured on a culture plate control (a), poly(DMA-MEA)-coated surface (b), methanol-treated surface (c), or an adhesive resin (Scotchbond) coated surface (d) for 1 day. In these fluorescence images (a–d), live or dead cells were stained in green or red, respectively. The cell viability of these cell cultures was determined by the WST cell viability assay (e). The scale bar represents 100 μm.
