Abstract: The present invention relates to systems, compositions, and methods for multi-cellular bioprinting of vascularized tissue constructs comprising hierarchical vascular networks. The method employs a dual-bioink strategy involving a fibrous microgel matrix bioink with tunable stiffness, self-healing rheology, and microporosity to support capillary self-assembly, and a sacrificial bioink that defines perfusable macro-channels upon removal. The system integrates top-down printing with bottom-up cellular self-organization within a programmable bioprinting platform. A key inventive aspect lies in engineering the physical topography of the matrix to actively guide vascular morphogenesis, moving beyond conventional permissive scaffolds. The integrated platform enables the fabrication of complex, biomimetic vascular networks with enhanced mass transport, cell viability, and in vivo integration potential.
