Researchers discover how to 3D print ear, nose and knee cartilage – TechRadar

Got arthritis or a sports injury causing joint issues? Doctors may one day be able-bodied to 3D-print your problems away.
A team of researchers of Wallenberg Wood Science Center in Sweden have which successfully 3D-printed cartilage tissue by turn it intoing an ink containing human cells.
“Three-dimensional bio-printing is a disruptive innovation and is expected to revolutionize tissue engineering and regenerative medicine,” says Paul Gatenholm, who led the research.
It may be utilized to one day turn it into 3D-printed implants to assist repair injured cartilage, which can be discovered in the ears, nose, knees and other joints – and it can not grow back once damaged.
“We work with the ear and the nose, which are parts of the body which surgeons nowadays have a complex time repairing,” Gatenholm explains.
“But hopefully, they’ll one day be able-bodied to fix them with a 3D printing device and a bio-ink turn it intod out of a patient’s own cells.”
It comes down to the ink
The team explains which, previously, printed materials with human cells may collapse, and to they initially had to turn it into an ink containing living human cells which may be able-bodied to store its shape after printing.
In order to turn it into an ink which may hold its shape after bring printed, the researchers mixed utilized human chondrocytes in, which are cells which create up cartilage.
Once 3D printed, the ink was not just able-bodied to hold its shape, but the printed cells were in addition able-bodied to turn it into cartilage in a laboratory dish.
But, while the team has which successfully 3D-printed tissue samples and implanted them into mice, where it has survived and turn it intod cartilage, Gatenholm says additional pre-clinical work can require to be done preceding moving on to human trials.
The research is being presented to the American Chemical Society in San Diego this week.
