Fig. 6From: Synergistic effect of chitosan-alginate composite hydrogel enriched with ascorbic acid and alpha-tocopherol under hypoxic conditions on the behavior of mesenchymal stem cells for wound healingWeight loss assay over 21 days (n = 3). a Data showed that biodegradability increased when AA was added to the CA structure. Tow-way ANOVA and Tukey post hoc analysis, ****p < .0001, ***p < .001, **p < .01 and *p < .05. b Images of lyophilized composite hydrogels before and after degradation (n = 3)Back to article page
