WHAT’S BEING CLAIMED:
- Cauliflower ears, familiar to most athletes such as boxers and wrestlers, will soon have a risk free treatment.
- With the help of 3D-printing technology, cell regeneration will soon help those who don’t want to undergo surgical procedures.
- By implanting a microchip to the disfigured skin or flesh, the “bio-ink” can trigger the tissue regenerating process.
Boxers, rugby players, and wrestlers could mend their malformed cauliflower ears through a simple injection procedure.
Chinese experts have recently come up with a 3D-bioprinting machine that can generate new tissue without invasive surgery.
The latest development means that star athletes such as Dan Cole, Graham Rowntree, and Richie McCaw, can now avoid unwanted comments about their mutilated ears.
The team of researcher’s approach was a non-invasive method to 3D-print new ears for mice, a process that forms layers of flesh, similar to conventional printing of spare parts in the industry.
But as a substitute with ink, the experts formulated a mixture of chemicals and tendon cells that were applied under the ear’s back skin. Reports show that the new tissue started developing instantly, fixing genetically disfigured earlobes of the lab rats.
In just a month, the cartilage had kept its shape and been populated by blood vessels and muscles to aid in growth and regeneration.
The study, which was published in Science Advances, stated the bio-ink could be controlled using rays of close to digital infrared light.
A microchip called a digital micromirror device (DMB) programmed with a unique pattern was easily implanted underneath the mouse’s skin, so the “bio-ink” can take effect on the new tissue.
The study showed that after rectifying the disfigurement, the fringe looked normal, and the group theorizes the method can also be applicable to humans.
Professor Maling Gou of Sichuan University, China, co-author of the study, said the 3D printing innovation presents significant potential in the advancement of clinical technology.
The advancement can also help create other body parts, eliminating the need for risky procedures soon as skin replacement technology is expected to become available in the next few years.
Professor Gou added, citing the result of their study, that the technology may lessen the injury risk for humans who traditionally undergo surgical implantations.
On a separate study last year, Israeli researchers revealed the first heart made up of human tissue, which was printed in 3D.
Since 2014, scientists from the University of Edinburgh have been attempting to create a bio-printed liver.
Gou further noted that using bio-ink for bio-printing, which contains cells to 3D-print living tissues or organs, can significantly be used in the field of regeneration medicine. Even without the need for implants through surgery, the living tissue constructs have generated without complications in the body.
