Fig. 5. Proliferation and spread of hFOB cells cultured on the GelMA, G-LALN, G-MALN and G-HALN hydrogels. (a) Confocal fluorescence microscopy images of the hFOB cells stained with a live/dead reagent on days 1, 4 and 7. The live and dead cells were stained green and red, respectively. The scale bar is 500 μm. (b) CCK-8 assay of the hFOB cells on the CS and CS-P scaffolds after 1, 4, and 7 days of culture.
