WEB DESK: For years, scientists have been able to “print” types of human tissue using a 3D printer, but in a significant leap forward by US and Australian researchers they can now make that tissue survive on its own, Guardian reported.
This essential process is called “vascularisation” and is necessary if researchers are to ever prevent cells from dying so they can grow large, transplantable organs.
Using a high-tech “bio-printer”, the researchers fabricated tiny, interconnected fibres to serve as the mould for the artificial blood vessels.
Biomedical engineer and a leader of the research, the University of Sydney’s Dr Luiz Bertassoni, said printing organs may still be a couple of decades away, but this was a “great step” towards achieving that goal.
“Thousands of people die each year due to a lack of organs for transplantation,” Bertassoni said.
“Many more are subjected to the surgical removal of tissues and organs due to cancer, or they’re involved in accidents with large fractures and injuries.
“While printing organs may be a couple of decades away, I also wouldn’t be surprised if I was wrong about that because this type of engineering is moving so rapidly.
“I would so love to be wrong.”
