Cell viability measured using the MTT assay for SMCs on different surfaces. Experiments were replicated on at least three different samples with at least three different cell populations (nmin = 9). Statistical significance was calculated using a one-way ANOVA with Tukey’s post hoc test. Results indicate after one day in culture that SMCs on the colNW surfaces have significantly lower MTT reduction than the PCL, NW and colPCL surfaces, whereas, there is no significant difference between the PCL, NW and colPCL surfaces. After seven days in culture, SMCs have a significantly higher MTT reduction on colPCL than the PCL, NW and colNW surfaces. Further, there were significant differences between PCL, NW and colNW surfaces (PCL > NW > colNW). Error bars represent the standard error.
