Amygdalin promoted angiogenesis in the newly formed callus around the fracture. (a) Three-dimensional images and quantification of angiography around the fractures in control and amygdalin-treated mice 10 days after surgery. Quantification shows the vessel volume. Scale bar = 1 mm. (b) CD31 protein expression was assessed by immunohistochemistry in control and amygdalin-treated groups (day 10). Blue arrows: CD31-positive cells. Scale bar = 50 μm. Data are presented as mean ± standard deviation (SD). ∗P < 0.05, n = 6.
