Cell growth dynamics of DPSCs cultured on type I collagen (COL) under xenogeneic serum-free medium (XFM) culture conditions. a Growth curve of COL-XFM and XFM cells during 20 days of culture. *p < 0.05; **p < 0.01. b Phase-contrast images of COL-XFM and XFM cells on day 6 (D6; the logarithmic phase) and on day 20 (D20; the overconfluent phase) post-seeding. c Histology of COL-XFM and XFM cultures on day 10 (D10; confluence) and on days 14 and 20 (D14 and D20; overconfluence); hematoxylin and eosin staining. All scale bars, 100 μm
