There are two mistakes in Figure 3a, where it shows the migration of endothelial cells and HFF-1. In order to ensure the scientificity of the conclusion, the cell migration pictures were replaced in the new Figure 3. These mistakes do not affect the results of this study. The authors apologize for the careless handling of the data. The corrected image is given herein.
Figure 3.
In vitro cell responses to hydrogel: (a) cell migration and tube formation; (b) strontium release curve; (c) HFF-1 viability via CCK8; (d) endothelial cell viability via CCK8; (e) VEGFA expression of the endothelial cell under different interfering conditions; (f) quantification of migrated cells; (g) quantification of tube formation.
