Collagen membranes were characterized in terms of permeability. (A) Permeability of various membranes were measured: Polycarbonate transwell membrane (PC Transwell), polyester (PE), collagen (UT), and enzymatically treated (Col-2+) membranes. Significant differences (p < 0.05, Student’s t test) are denoted by an asterisk. (B) Effect of cell seeding on collagen membranes by means of permeability. Nontreated collagen membranes (UT), nontreated membranes with ARPE-19 cells seeded (UT+ ARPE-19), and enzyme-treated membranes (Col-2+ ARPE-19) were measured. Significant differences according to one-way ANOVA and Posthoc Tukey’s tests are indicated by asterisks.
