Immunofluorescence staining of β1-integrins in human dermal fibroblasts on day 3 after seeding on nonmodified PLA membranes or on PLA membranes with a fibrin nanocoating (F).
Notes: Arrows show focal adhesions containing β1-integrins. The cells were cultivated in the standard cell culture medium or in the medium supplemented with AA. Microscopic glass coverslips (GLASS) served as a control material. Cell nucleus stained with Hoechst #33258 (blue). Leica TCS SPE DM2500 confocal microscope, obj 63×/1.3 NA oil.
Abbreviations: PLA, polylactide; AA, 2-phospho-l-ascorbic acid trisodium salt; obj, objective; NA, numerical aperture.
