Comparison of cell attachment of retinal pigment epithelial cell line (ARPE-19) on tissue culture plastic (TCP) coated with either fibroin solution, or fibroin mixed with increasing concentrations of tropoelastin (proteins blended in solution before coating TCP). Evidence of cell attachment was examined after 4 h in either the presence or absence of 10% (v/v) fetal bovine serum (with washing prior to measurement). Each substrate was tested in triplicate. Bars represent mean values ± standard error of the mean from three experiments. The difference between fibroin with 10% tropoelastin used in the presence of serum and the other identified bars was statistically significant (p < 0.05).
