Figure 9. Quantification of Alizarin Red staining (ARS) for GelMa-based constructs with and without human mesenchymal stem cells (hMSCs) after 7
and 14 days. (A) ARS quantification of cell-free scaffolds (n = 4). (B) ARS quantification of cell-loaded constructs for four donors on days 7 and 14. (C–F)
Individual ARS quantification of the constructs for four donors, respectively (n =3 technical replicates). (G) Comparison of GelMa-based constructs with
(cells) and without (no_cells) hMSCs on day 7 (n =4 donors). (H) Comparison of GelMa-based constructs with (cells) and without (no_cells) hMSCs on
day 14 (n = 4 donors). Statistics were evaluated using two-way ANOVA; *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. Abbreviations: ANOVA: Analysis
of variance; GelMa: Gelatin methacrylamide; BB: Brilliant Black; CaP: Calcium phosphate; GO: Graphene oxide.
