FIG. 5.

Cell viability of macrophages seeded on the surface of each scaffold. Live/dead viability staining was performed after 48 h of culture to label the cytoplasm of viable cells with calcein-AM (green) and the nuclei of dead or dying cells with ethidium bromide (red) (A–C, scale bar represents 200 μm). Total viability was quantified as a ratio or viable/dead cells (D) and as the percentage of total cells that are viable and dead (E) (error bars represent±one standard deviation, n=3).
