Researchers have made a giant leap towards the goal of ‘bio-printing’ transplantable tissues and organs for people affected by major diseases and trauma injuries, a new study reports.
Scientists from the Universities of Sydney, Harvard, Stanford and MIT have bio-printed artificial vascular networks mimicking the body’s circulatory system that are necessary for growing large complex tissues.
“Thousands of people die each year due to a lack of organs for transplantation,” says study lead author and University of Sydney researcher, Dr Luiz Bertassoni.
“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.
“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 in your computer screen.
“We are still far away from that, but our research is addressing exactly that. Our finding is an important new step towards achieving these goals.
“At the moment, we are pretty much printing ‘prototypes’ that, as we improve, will eventually be used to change the way we treat patients worldwide.”
The research challenge – networking cells with a blood supply.
