Tissue sections were stained for Von Willebrand (VW) factor and observed at ×100 magnification. ((a), (c), and (e)) TCP group. ((b), (d), and (f)) HP group. ((a), (b)) 1 month. ((c), (d)) 3 months. ((e), (f)) 12 months. (g) Measurement of the number of infiltrating vessels. β-TCP (grey box), HA/PDLLA (black box). Most of the vessel cavities were present in the infiltrated fibrous tissue; the HP groups showed significantly more vessel cavities than did the TCP groups during the follow-up period. : versus TCP group. †: versus 1 month. §: versus 3 months. Scale bars: 200 µm.
