PF-127 hydrogel possesses larger interconnected pore and higher biocompatible capacity compared to C/GP hydrogel. (a) Photographs of PF-127 and C/GP hydrogel. (b) SEM images of PF-127 and C/GP after 24-hour freeze drying process. Scale bar = 300 μm. (c) Quantification of porosity of PF-127 and C/GP hydrogel. Data was reported as mean ± S.E.M of 5 SEM images with 200× magnification, tested for significant difference (∗∗P < 0.01) using Student's t-test. (d) Comparison of pore size of PF-127 and C/GB hydrogel. Results were presented as mean ± S.E.M of approximately 50 pores from 5 SEM images with 100× magnification. Significant difference test was performed with Mann–Whitney rank sum test (∗P < 0.05). (e) Q-PCR analyzed the relative gene expression of inflammatory factors (Tnfa, Ifng, and Il2). Data was reported as mean ± S.E.M. Student's t-test was applied for significant difference (∗∗P < 0.01), n = 16.
