The expression of osteogenic-related genes. Relative expression of A BMP2, B BGLAP, C RUNX2 and D SPARC by hDPSCs seeded on gelatin, PCEC/Gel, PCEC/Gel-Fe3O4, PCEC/Gel-HA, PCEC/Gel-Fe3O4&HA scaffolds after 21 days by real-time PCR analysis. The values were normalized to GAPDH. (*p < 0.05, **p < 0.01, and ***p < 0.001)
