Histological analysis of newly regenerated bone after implantation of hASCs and/or periostin.

<p>(A) H&E staining of calvarial defects eight weeks after implantation of hASCs and/or periostin. Higher magnification images of the regions highlighted by the black box in left panels are shown in right panels. Scale bar = 100 μm. (B) Area of newly regenerated bone tissues was determined in the defected bone and the percentage of bone area per healed area was calculated. Data represent mean ± S.D. (n = 8). *, p < 0.05 vs control.
