Human bronchial epithelial cell (HBEC) adherence, survival and growth on POSS-PCU. Metabolic activity of the cells on the four different scaffolds and the collagen-coated tissue culture plastic (TCP) control over 5 days are expressed as the percentage of alamarBlue reduced in the cells during the incubation. Experiments were performed in triplicate and analyzed using two-way ANOVA tests with Bonferroni post-tests. Statistical significance is displayed as *p < 0.05, **p < 0.01, ***p < 0.001.
