Fig. 5From: Development of a composite hydrogel incorporating anti-inflammatory and osteoinductive nanoparticles for effective bone regenerationBiocompatibility of composite cryogels. (a) Fluorescence images of hADSCs attached to the surfaces of cryogels stained for F-actin with Alexa Fluor™ 488 Phalloidin (scale bar = 50 μm). (b) Quantification of the DNA content of hADSCs cultured on the cryogels for 1 day (n = 3). (c) LIVE/DEAD images of hADSCs cultured on the cryogels for 1 and 4 days (scale bar = 200 μm) and (d) quantification of DNA content (*, significant difference from day 1 in each group, P < 0.05) (n = 3)Back to article page
