L-929 mouse fibroblasts grown on the coatings for 48 h. (A) GlcNAc-2EG-PDMAm, (B) GlcNAc-4EG-PDMAm, (C) 10%-GlcNAc-4EG-PDMAm, (D) GlcNAc-6EG-PDMAm, (E) PDMAm, (F) untreated cell culture dish. Morphology is altered to some extent, but cell viability is still given as shown via MTT test in Figure 7, in which the shown polymers show no more than 20% reduction in cell viability, so no cytotoxicity can be assumed.
