Abstract:
We report an in situ light-mediated reinforcement strategy for spatial microvascular patterning. Laser-patterned stiff zones in AlgMA/fibrin hydrogels suppress capillary formation by >81%. A linear stiffness-density relationship (R2 > 0.78) enables predictable engineering of heterogeneous tissue architecture.
