Fluorescent images of HEK after 7 and 14 days on PLCL scaffolds, proliferation assessed using Live/Dead assay. (a) 0 mg(Ag) g(scaffold)−1, 7 days; (b) 0.1 mg(Ag) g(scaffold)−1, 7 days; (c) 0.5 mg(Ag) g(scaffold)−1, 7 days; (d) 1.0 mg(Ag) g(scaffold)−1, 7 days; (e) 0.0 mg(Ag) g(scaffold)−1, 14 days; (f) 0.1 mg(Ag) g(scaffold)−1, 14 days; (g) 0.5 mg(Ag) g(scaffold)−1, 14 days; (h) 1.0 mg(Ag) g(scaffold)−1, 14 days. Live cells stain green and dead cells stain red. Magnification of 10× for all images.
