TL;DR: An integrated tissue–organ printer (ITOP) that can fabricate stable, human-scale tissue constructs of any shape is presented and the incorporation of microchannels into the tissue constructs facilitates diffusion of nutrients to printed cells, thereby overcoming the diffusion limit of 100–200 μm for cell survival in engineered tissues.

TL;DR: This approach relies on development of a target-specific biomaterial scaffolding system that can effectively control the host microenvironment and mobilize host stem/progenitor cells to target tissues.

TL;DR: 3D bioprinting strategy was applied to fabricate an implantable, bioengineered skeletal muscle tissue composed of human primary muscle progenitor cells (hMPCs) and showed a highly organized multi-layered muscle bundle made by viable, densely packed, and aligned myofiber-like structures.

TL;DR: It is demonstrated, for the first time, that vascularized bioengineered livers, of clinically relevant size, can be transplanted and maintained in vivo, and represents the first step towards generating engineered livers for transplantation to patients with end-stage liver failure.

TL;DR: The results suggest that the 3D bioprinted human neural-skeletal muscle constructs can be rapidly integrated with the host neural network, resulting in accelerated muscle function restoration.
