These vessels may not function inside an organ as well as progenitor cells from that organ. Location and timing also were crucial to achieving the initial vessel formation.

Bioprinting holds the promise of engineering organs on demand. Now, researchers have solved one of the major bottlenecks—how to create the fine networks of blood vessels needed to keep organs alive.

Blood vessels are essential to nearly all tissues, delivering nutrients and oxygen, regulating hemostasis, and modulating inflammation.

Tiny balls of lab-grown blood vessels helped restore blood flow to injured tissue in mice, minimising necrosis. This approach could one day be used to reduce some of the damage caused by accidents ...

A computational model that could rapidly design a blood vessel network for any 3D-printed organ may take us a step closer to transplanting artificial livers, kidneys or hearts without the need for ...

For over a decade, scientists have been growing organoids—small clusters of cells that mimic a particular organ—to serve as miniature biological models. Organoids of the brain have been used ...

A chip with natural blood vessels Date: May 27, 2025 Source: Vienna University of Technology Summary: Miniature organs on a chip could allow us to do scientific studies with great precision ...

Miniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs ...

ASU scientists pioneer a 3D-printed blood vessel design that mimics nature, offering hope for safer, more adaptable cardiovascular treatments.

The agency OK’d an artificial vessel to restore blood flow in patients, even though its own scientists flagged questionable study results and potentially fatal ruptures of the product.

KOMAN is helping craft the bodies of technology and machinery powering the industrial future with its hydraulic hoses and fittings.

In the brain, not all blood flow is created equal. RIKEN researchers have developed a detailed cortical layer map of the blood vessels that weave through the brain of macaque monkeys. It reveals ...
