Aim of this project is the biofabrication of artificial vascular structures with correct hierarchical organization and wall morphology consisting of intima, media and adventitia. This shall be reached by the exploitation of the cellular plasticity of vascular wall-resident stem cells (VW-SCs). These cells have been shown to possess the necessary cellular plasticity to deliver such structures. By the printing of VW-SC loaded bioinks into self-healing support gels, the use of vessel wall specific matrix components and perfusion of the structures, we aim on a medium to long term to biofabricate complex and hierarchically organized vascular structures.
