Fig. 9From: Biomineralized tetramethylpyrazine-loaded PCL/gelatin nanofibrous membrane promotes vascularization and bone regeneration of rat cranium defectsHistological staining results for the different membranes in the rat cranial defect model at 8 weeks post-surgery. A H&E staining images of regenerated tissue. B The quantitative analysis of H&E staining. C Masson’s trichrome staining images of regenerated tissue. D The quantitative analysis of Masson’s trichrome staining. * p < 0.05, ** p < 0.01, *** p < 0.001, vs. defect alone with no implanted materials group; # p < 0.05, vs. PG group; & p < 0.05, vs. PGH group.
