flippe-floppe-flye may be onto something here

To 3D print vascular networks, the researchers fabricated fine, interconnected fibers with an advanced bioprinter. Then they coated those fibers with human endothelial cells — these sit between circulating blood and vessel walls in the interior of blood vessels — and subsequently applied a protein-based material. They hardened the whole structure with light, then delicately removed the fibers, leaving behind an complex network of hollow cell material. After a week, those cells organized themselves into stable capillaries.

Cells inside the bioprinted vascular networks survived, differentiated, and proliferated at better rates than cells that received no nutrient supply, the study found.

“Imagine being able to walk into a hospital and have a full organ printed — or bio-printed, as we call it — with all the cells, proteins, and blood vessels in the right place, simply by pushing the ‘print’ button on your computer screen,” said Bertassoni.

I hold DDD from almost the exact bottom of the NASDAQ meltdown. I must confess that I was unaware of the bio-printing. If this is successful, then these stocks could go much higher.

One for Mr flippe-floppe.
