Anti-oxidative effect of the composite cryogels. (a) Analysis of the ROS scavenging effects of MPs and TMPs with different concentrations (0, 2, 10, 50 µg/mL) as shown by Fe conversion (left) and ABTS inhibition assays (right) (n = 3), and (b) cryogel results from the Fe conversion (left) and ABTS inhibition assays (*, **, ***, significant differences from the other groups, P < 0.05) (n = 3). (c) The experimental conditions used to assess the survival rate of hADSCs cultured under oxidative stress induced by H2O2. (d) LIVE/DEAD images of hADSCs cultured on cryogel surfaces for 1 day under high ROS conditions (scale bar = 200 μm) and (e) quantitative results for living cells analyzed from LIVE/DEAD images (n = 5)
