Effects of hASCs and periostin on angiogenesis in calvarial defects.

<p>(A) Immunostaining of endothelial cells and smooth muscle cells in calvarial defects implanted with hASCs and/or periostin. The specimens were immunostained with anti-CD31 (red color) or anti-α-SMA (green color) antibodies, and overlaid images with nuclei (blue color) are shown. Scale bar = 50 μm. The numbers of CD31-positive capillaries (B) and α-SMA-positive blood vessels (C) per high power field were counted. Data represent mean ± S.D. (n = 8). #, p < 0.05; *, p < 0.05 vs control.
