A novel strategy for engineering vascularized grafts in vitro

Figure 1 Strategy for prefabrication a scaffold with hollow vascular network. A: The scaffold is prefabricated in an layer by layer manner; B, C: The hierarchical vascular-like network made of ‘low-melting point’ material. The black squares represent the basic units; D: The basic unit of microcirculation-like net which is 250 um × 250 um in size. The diameter of the capillary-like line is 10 um.
