Plots of distribution of blood vessel areas in the scaffolds with pore sizes of (A) 79, (B) 147, (C) 224, and (D) 312 μm, respectively, at 2 weeks (left column) and 4 weeks (right column) post implantation. The data were measured from hematoxylin and eosin stained tissue sections obtained at approximately 200 μm in depth from the top surface of the scaffolds. The data are presented as mean ± standard deviation (n = 4). For each sample, at least 200 blood vessels from 8 tissue sections were examined.
