Figure 7.

Analysis of the effects of PDMS loaded with increasing concentrations of r(P)ApoB_L^Pro on the viability of human dermal fibroblasts (HDF) (a) and of murine BALB/c-3T3 fibroblasts (b). Cell viability was assessed by MTT assays and expressed as the percentage of viable cells with respect to cells incubated with unfunctionalized PDMS. Experiments were performed three times. Error bars represent the standard deviation of the mean. Significant differences were indicated as * (p < 0.05) for treated vs. control samples.
