Fig. 5From: Multifunctional thermo-sensitive hydrogel for modulating the microenvironment in Osteoarthritis by polarizing macrophages and scavenging RONSRONS scavenging capacity of HPP@Cu gel for RAW264.7 and chondrocyte. a Confocal fluorescence images of the levels of ROS of RAW264.7. b Confocal fluorescence images of the levels of RNS of RAW264.7. c Confocal fluorescence images of the levels of ROS of chondrocyte. d Confocal fluorescence images of the levels of RNS of chondrocyte. e–h Corresponding to a–d, the mean fluorescence intensity was quantified by ImageJ, respectively. In e–h, data represent means ± SD, n = 3. *p < 0.05, #p < 0.05, and &p < 0.05. **p < 0.01, ##p < 0.01, and &&p < 0.01. NS means not significantBack to article page
