'Printer' Designs Living Tissue

SAN DIEGO, June 4 (UPI) — A machine already capable of growing new arteries may one day be able to “print” new organs for transplant, scientists in California said.

The bioprinter developed by Organono in San Diego is based on the 3D laser technology used to create new machine parts for industry. Instead of combining layers of plastic and metal, the bioprinter combines living tissue, said Keith Murphy, Organono’s chief executive officer.

Two printing heads place living cells onto thin sheets of gel with microscopic precision, he said. Multiple layers are then laid on top of each other and the cells begin to fuse.

“Ultimately the idea would be for surgeons to have tissue on demand for various uses,” Murphy said.

Murphy said his company aims to get numerous bioprinters into the hands of researchers to give them the ability to make living tissue available when needed, The Daily Telegraph in London reported Friday.
