Immunohistochemistry staining results for different membranes in a rat cranial defect model at 8 weeks post-surgery. A Representative immunohistochemistry (IHC) staining images of Runx2, OPN, and OCN. B Semiquantitative analyses of IHC staining results from (A) (n = 8). * p < 0.05, ** p < 0.01, vs. defect alone with no implanted materials; ^## p < 0.01, vs. PG membrane; ^& p < 0.05, vs. PGH membrane
