Fig. 6: FSHR expression and MVD (per 200X field) changes on the GO/PLLA nanofiber scaffolds.

a Representative images of immunohistochemical staining for FSHR show the growth of GCs on the 0.0 wt% and 1.0 wt% GO/PLLA nanofiber scaffolds. The dotted red frame shows the growth of GCs in a circular pattern. b The expression levels of FSHR on 0.0 wt% and 1.0 wt% GO/PLLA nanofiber scaffolds. c Localization and expression of CD31 and CD34 on the 0.0 wt% and 1.0 wt% GO/PLLA nanofiber scaffolds. The red arrows indicate blood vessels. d Comparison of MVD by CD31 and CD34 on 0.0 wt% and 1.0 wt% GO/PLLA nanofiber scaffolds. Statistical significance levels are set at *P < 0.05, **P < 0.01 by two-tailed Student’s t-test, Data are presented as mean ± SD, scale bar: 200 μm.
