Scaffold vascularity imaging: The classic (a) and flow-through prefabrication (b) groups were assessed through post-mortem and in vivo μCT imaging (c, d respectively). Small vessels with perfusion that sprouted from the main vascular pedicle were observed in the flow-through prefabrication group (b, d). In the classic prefabrication group, vessel ingrowth was noted only on the outer surface of the scaffold adjacent to the vascular pedicle (a, c)
