The corrected Fig. 2 is given below. These corrections do not change or affect the results or conclusions of the paper. Figure 2 Biocompatibility and cytoprotection of PPAH. (a) Viabilities of astrocytes and PC12 cells after incubation with PPAH for 24 h (n = 3). (b, c) Protective effect of PPAH against (b) 200 and (c) 400 μM acrolein-induced damage on astrocytes and PC12 cells (n = 3). (d) Morphology of astrocytes treated with 200 μM acrolein followed by different concentrations of PPAH under light microscopy. Scale bar = 100 μm. (e) Relative LDH release level of PC12 cells after incubation with 200 μM acrolein and different concentrations of PPAH for 24 h (n = 3). (f) Fluorescence microscopy images of AcroleinRED in astrocytes after being treated with 200 μM acrolein followed by different concentrations of PPAH. Scale bar = 100 μm. ***P < 0.001; **P < 0.01; *P < 0.05 compared with the control group. 1 Key Laboratory of Polymer Ecomaterials, Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, Changchun 130022, China University of Science and Technology of China, Hefei 230026, China 3 Department of Orthopaedic Surgery, China-Japan Union Hospital of Jilin University, Changchun 130033, China 4 Jilin Biomedical Polymers Engineering Laboratory, Changchun 130022, China * Corresponding author (email: ; ; ) 2 © Science China Press 2024 1  (...truncated)
