Fig. 1 — Cell viability and migration. A MTT assay for the evaluation of hDPCs after 24, 48, and 72 h of culture with the tested biomaterials and negative control (unconditioned medium). Asterisks designate significant differences compared to the control. *p < 0.05; **p < 0.01; ***p < 0.001. B The migration ability of hDPCs when cultured with the different material extracts was analyzed using a scratch wound assay. Images were captured every 24 h for 72 h using a phase-contrast microscope (× 100 magnification) and four standardized points were evaluated (0, 24, 48, and 72 h)
