Morphology of HP and HP-bFGF hydrogels and cytocompatibility of hydrogels with DPSCs. (a) SEM images of HP and HP-bFGF hydrogel. Scale bar: 100 μm. (b) Quantification of pore density and pore size. (c) Live/Dead staining of cells in HP and HP-bFGF hydrogels at 48 hours. Scale bar: 200 μm. (d) Quantification of live cells in HP and HP-bFGF hydrogels by Image J. Data were displayed in mean ± standard error from 3 rats in each group. , versus HP group.
