New bone regeneration enhanced by PGHT membrane in a rat cranial defect model. A, B micro-CT scan images at 4 (A) and 8 (B) weeks post-surgery. The newly formed bone tissue is marked in red within the 5-mm diameter circle. C Bone mineral density (BMD). D Percent bone volume (BV/TV). E Trabecular number. F Connectivity density (Conn. Dn) (n = 8). *p < 0.05, **p < 0.01, ***p < 0.001, vs. defect alone with no implanted materials; ^#p < 0.05, ^##p < 0.01, vs. PG membrane; ^&p < 0.05, ^&&p < 0.01, vs. PGH membrane
