Various methods of bioprinting used in the development of bioengineered cancer tissues. (A) Components of inkjet, microextrusion based and laser-assisted bioprinters. (B) A scheme showing the multi-cartridge module based Integrated Tissue Organ Printer (ITOP) system consisting of stage/controller, dispensing module with pressure controller and a closed chamber. (C) Schematic diagram of a two-step 3D bioprinting method in which hiPSC-HPCs were patterned by the first digital mask followed by the patterning of supporting cells using a second digital mask.
