TL;DR: A novel 3D bioprinting method based on hollow calcium alginate filaments by using a coaxial nozzle, in which high strength cell-laden hydrogel 3D structures with built-in microchannels can be fabricated by controlling the crosslinking time to realize fusion of adjacent hollow filaments.

TL;DR: 3D hydrogel-based vascular structures with multilevel fluidic channels (macro-channel for mechanical stimulation and microchannel for nutrient delivery and chemical stimulation) were fabricated by extrusion-based threeD bioprinting, which could be integrated into organ-on-chip devices that would better simulate the microenvironment of blood vessels.

TL;DR: Thymoquinone effectively inhibits tumor growth and angiogenesis both in vitro and in vivo, and inhibition of NF-κB and downstream effector molecules is a possible underlying mechanism of the antitumor and anti-angiogenic activity of thymOquinone in osteosarcoma.

TL;DR: The findings demonstrate that the side-wall pore architecture in 3D printed bioceramic scaffolds is required to optimize for bone repair in calvarial bone defects, and especially the Mg doping wollastontie is promising for 3D printing thin-wall porous scaffolds for craniomaxillofacial bone defect treatment.

TL;DR: The results of this study demonstrate that fabricating surgical implants at the clinic with D3DPs can be feasible, effective, and economical.
