a) Cell viability of Hs27 cells upon seeding on A/S mixture-loaded CA scaffolds after 3 and 7 days. Cell viability values are expressed as the percentage of viability observed in neat sample (control – 100% cell viability) for the two timepoints. b) Cell viability of Hs27 cells upon treatment with various A/S derivatives. * indicates p < 0.05 compared to untreated (control) cells. Cell viability values at day 1 are expressed as the percentage of viability observed in untreated cells (100% cell viability), while cell viability percentages at day 3 are normalized based on the 24 h viability values. Data are shown as the mean of three individual experiments ± SD
