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.

Researchers are using ice as a template for the 3D printing of artificial blood vessels in engineered tissues, which could one day be utilized for artificial organ transplants and drug testing.

Over 100,000 individuals in the United States are currently in need of organ transplants. The demand for organs, such as hearts, kidneys, and livers, far exceeds the available supply and people ...

In his lab, Yuxiang Zhu leaned over a softly humming 3D printer, his face lit by the faint glow of a nearby monitor. Beneath the printer's nozzle, a thick blend of seaweed-derived sodium alginate and ...

The formation of blood vessels is a complex process involving the interplay of proteins and mechanic forces. In two studies, a research team has uncovered new mechanisms in blood vessel formation. The ...

Complex artificial organs could be created by 3D printing a mould of veins, arteries and capillaries in ice, casting that in organic material and then allowing the ice to melt away, resulting in a ...

Lab-grown organs for transplant are one step closer thanks to a technique for making artificial blood vessels using 3D printers and liquid metal. One challenge in developing organs in the lab is to ...

Brain aneurysms, often silent threats, can rupture unexpectedly, causing life-threatening hemorrhages. Weakened blood vessels ...

Weill Cornell Medicine researchers have determined the full-length structure of a blood pressure-regulating hormone receptor for the first time, uncovering how it functions, which may enable better ...
