Characterization of the mechanical property of GelMA hydrogel and the hMSC behaviors on different stiffness of GelMA hydrogels w/wo IL-1β treatment. (A) Shown are GelMA hydrogels with high, medium, and low stiffness. (B) CCK-8 quantitative analysis of hMSCs viability on day 3 is shown. (C) Shown are F-actin/DAPI fluorescence images of hMSCs spreading after 12 and 24 h of culture. Scale bars, 100 μm. (D) Shown is the quantification of the staining of cell spreading area after 12 and 24 h of culture by the ImageJ software. ∗ indicates p < 0.05. To see this figure in color, go online.
