Figure Legend:
Hybrid bioprinting of scaffold-based vascular constructs in tandem with scaffold-free parenchyma tissue, where fusion, tissue remodeling, and self-assembly of tissue strands take place and sprouting can take place between the macrovascular network and capillaries in tissue strands. This concept generalizes the tissue used; however, for different tissue types, modifications on the system would be essential.
