3D bioprinting. (a) Schematics representation of the microfluidic printing head (MPH) coupled to a co-axial nozzle extruder employed to simultaneously bioprint iPSC-derived cardiomyocytes and HUVEC cells. (b) Bioprinted cellularized 10-layers thick construct. Higher magnification image of the same construct is presented in the box below. Scale bars represent 1 cm and 100 µm, respectively (c) Diagram showing the procedure for the fabrication of covalently crosslinked PEG-Fibrinogen based scaffolds prior to undergo in vitro culture.
