Effects of hASCs and/or periostin on regeneration of calvarial bone defects.

<p>(A) Masson’s trichrome staining of calvarial defects (blue color: mineralized bone tissue; red color: non-mineralized bone tissue). Higher magnification images of the regions highlighted by the black box in left panels are shown in right panels. (B) The gap of calvarial defects in the Massons’s trichrome staining images was quantified and shown as the distance between the advancing edges. Data represent mean ± S.D. (n = 8). *, p < 0.05 vs control.
