Design of the microfluidic chip for the vascularized tumor model. A) Explosive view of the 3D vascularized lung cancer model within the hydrogel composite. B) Cross‐sectional view of the hydrogel‐laden chip and the induction of interstitial flow. C) Experimental steps in the seeding of cells and induction of angiogenic sprouting by controlling the engineered tumor microenvironment. D) Fabrication steps for microvascular structure embedded in the composite hydrogel. E) Application of the vascularized tumor chip for evaluating the promoted transport of anticancer drugs, immune cells, and anticancer drug‐conjugated liquid metal (embolism materials).
