Surface treatment of PCL films using aminolysis, hydrolysis, fibronectin coating, and combined treatment of hydrolysis and fibronectin assessed to determine conditions for increased hPDL cell attachment. Data shows mean percentage of ligament progenitor cells adhered to non-treated PCL films in vitro versus surface-treated PCL at 1 and 5 days post-seeding. (Error bars: ± SD; ** p<0.01; *** p<0.001, **** p<0.0001; # indicates p<0.05 relative to non-treated PCL film at each timepoint; n=3).
