The viability and proliferation of DPSCs co-cultured with GelMA-bFGF hydrogels. (A) Live/Dead staining of DPSCs in GelMA-bFGF hydrogels at 5 days. (B) Quantification of the cells in GelMA-bFGF hydrogels by Image J. (C) The cell proliferation of DPSCs in GelMA-bFGF hydrogels at day 1, 3, 5, 7, and 9. Data were displayed in mean ± standard error from 3 replicates in each group. ∗∗P < 0.01, ∗∗∗P < 0.001 versus the 15% GelMA-bFGF group.
