a) LIVE/DEAD images of HFF-1 cells within ELR hydrogels after 1 day of incubation. (b) A single plane of a field (left) and the Z-projection of a Z-stack of the same field (right) are shown. Green-stained cells correspond to living cells, while red dots are dead cells. Scale bar = 100 µm. b. Morphology of cells within ELR hydrogels stained with Phalloidin-Alexa Fluor 488 for actin staining (in green) and DAPI for nuclei (in blue). A single plane of a field (left) and the Z-projection of a Z-stack of the same field (right) are shown. Scale bar = 100 µm.
