Viability and proliferation of NPCs in fucoidan-DexMA: (a) live/dead staining of NPCs cultured in hydrogel for 1 and 3 days. Green: living cells. Red: dead cells; scale bar, 200 μm, (b) quantitative analysis of live NPCs in the hydrogel scaffold, and (c) the proliferation of NPCs cultured in different materials for 1, 4, and 7 days was assessed using a CCK-8 kit (compared with the control group, *p < 0.05. **p < 0.01. ***p < 0.001. ns indicates no significant difference).
