Fig. 7: eNOS and p-eNOS expression levels in transplanted ovarian tissue in the three groups and NO production in the supernatant of granulosa cells co-cultured with different concentrations of GO/PLLA nanofiber scaffolds.

a Representative image of western blot. b Protein levels of eNOS and p-eNOS based on the relative gray value of the western blot. c The concentration of NO in the supernatant of GCs co-cultured with different concentrations of GO/PLLA nanofiber scaffolds. All the western blots were confirmed to be derived from the same experiment and processed in parallel. Statistical significance levels are set at *P < 0.05, **P < 0.01 by one-way ANOVA (Multiple comparisons). Data are presented as mean ± SD.
