Modulation of Dental Pulp Stem Cell Odontogenesis in a Tunable PEG-Fibrinogen Hydrogel System

Figure 4

Odontogenic differentiation of encapsulated DPSCs in PF hydrogels (PF-0, PF-0.5, PF-1.5, and PF-2.5) as a function of degree of cross-linking and culture time. Relative gene expression levels of Col I, DSPP, DMP-1, and OC were determined with respect to the day 0 expression level and presented as bar graphs using logarithmic scales. Mean ± SD: /group/time point. , , and , Fisher’s post hoc test.
