Engineering of biomimetic tissue implants provides an opportunity for repairing volumetric muscle loss (VML), beyond a tissue’s innate repair capacity. Here, we present thick, suturable, and pre-vascularized 3D muscle implants containing human induced pluripotent stem cell-derived myogenic precursor cells (hiPSC-MPCs), which can differentiate into skeletal muscle cells while maintaining a self-renewing pool. The formation of contractile myotubes and millimeter-long fibers from hiPSC-MPCs is achieved in chemically, mechanically, and structurally tailored extracellular matrix-based hydrogels, which can serve as scaffolds to ultimately organize the linear fusion of myoblasts. Embedded multi-material bioprinting is used to deposit complex patterns of perfusable vasculatures and aligned hiPSC-MPC channels within an endomysium-like supporting gel to recapitulate muscle architectural integrity in a facile yet highly rapid manner. Moreover, we demonstrate successful graft-host integration and de novo muscle formation upon in vivo implantation of pre-vascularized constructs within a VML model. This work pioneers the engineering of large pre-vascularized hiPSC-derived muscle tissues toward next generation VML regenerative therapies.
