Fig. 6. (A) Nioplex release kinetics from HA hydrogels in PBS and in PBS supplemented with collagenase I (1 U ml−1). (B) Transfection efficiency and cell viability of nioplex-loaded hydrogels 1–3 at 48 h. (C) Representative images of cell spreading in hydrogels 1, 2 and 3. Blue = cell nuclei (DAPI) and red = F-actin (rhodamine-phalloidin). Scale bars: 200 μm. *p < 0.05 for transfection efficiency.
