(a) Relative viability (to cell-only control) of ATDC5 cells treated with the hyaluronate–alginate hybrid (HAH) solution ([ATDC5] = 5 × 103 cells/well) and (b) images of ATDC5 cells encapsulated within the HAH hydrogels ([ATDC5] = 1 × 107 cells/mL; scale bar, 200 μm) as seen in the live/dead assay. The green and red signals indicate live and dead cells, respectively, in the gel. Cell viability was evaluated after 24 h of culture.
