Norwegian startup ClexBio is bioengineering human veins to implant inside a patients body.
Pre-clinical tests in animal models are already underway.
Instead, they turn into functional tissue that integrates with the body.

To produce them in a scalable fashion, the startup developed the bioreactor.
Inside the machine,the veins mature over a few weeks in a sterile environment.

Automated media circulation provides the tissue with oxygen and nutrients.
As the veins mature, the system forms them into a graft.
ClexBio said they can then be implanted into patients off the shelf.
Before that happens, the tech will have to pass an array of tests and clear regulatory reviews.
ButHatiis already imagining the real-world impact.
We are moving away from a world of synthetic implants and stepping into the world of bioengineering.
