A) MTT assay of hDPSCs cultivated on Gelatin, PCEC/Gel, PCEC/Gel-Fe3O4, PCEC/Gel-HA, PCEC/Gel-HA&F3O4 scaffolds. B, b) Alizarin Red staining was performed on day 14 to observe calcium and mineral deposits in nanocomposite scaffolds. The amount of Alizarin Red staining in different compounds was drawn with Prism software. The groups were compared by the one-way ANOVA, and they were then analyzed using the Tukey’s HSD, *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001
