Fig. 5. Cells are viable when seeded inside the cryogel. (a–f) Confocal merged images of Live/Dead assay on different days. Live cells are marked in green with calcein AM, dead cells are marked in red with EthD-1, and cell nuclei are counterstained in blue with DAPI. (g) Graphs of the viability results. CNTs(−) in light grey and CNTs(+) in dark grey. Results are mean ± SEM. *p-value = 0.05.
