University of Tokyo and Kyoto University. The researchers who carried out this fascinating study have grown an improved, adult-sized tissue-engineered ear in the laboratory.

Scientists in Japan report that they have successfully been able to grow a human ear on a rat’s back. For these unfortunates, there’s a new hope: artificially-grown ears. Human tissue is still required for this newly described research, but these days scientists can obtain stem cells from just a small sample of skin, so the procedure would be far less invasive.Scientists from Princeton University are also bridging electronics with biomaterials to create \"bionic ears.\" Frank WojciechowskiAfter turning human cells into an embryonic stem cell-like state, basically erasing their identity and turning them into a blank slate, the Japanese team coaxed them into becoming specialized cells that form cartilage. Forgot account? They weren’t photoshopped, but the ear was actually made from cow cartilage – no human tissue was involved. The scientists, from the university of Tokyo and Kyoto University, induced pluripotent stem cells to grow into ear cartilage, then placed the cells into a type of “biological tubing” that resembled a human ear, Discovery … Human Ear Grown On A Rat's Back. Just recently, researchers in Japan from the University of Tokyo and Kyoto University successfully grew an adult-sized “living” ear on the back of a rat using human stem cells.

The ambitious group from the University of Tokyo and Kyoto University has also claimed to the media that human trials could begin in just a span of five years. The artificial ear tissue was grown on a three-dimensional titanium "scaffold" — a wire frame designed to replicate the proportions of a human ear, which had been imaged with CT scanning. Still, it didn’t take long for misinformation to spread like wildfire in the media and give people false hopes that the pioneering technique could soon allow people with disfigurements or birth defects to grow their own replacements.Almost 20 years on, science has come a long way, and we might actually be close to a time where this is possible. The new tissue structure was then implanted into a rat with a suppressed immune system, recalling the controversial Vacanti mouse project from 1997. Cool—and/or creepy—news out of Japan, where researchers at the University of Tokyo and Kyoto University have created a human ear … on the back of a rat. The cells were grown on a titanium wire scaffold that is modelled on the dimensions of a real human ear, taken from CT scans. For example, scientists recently announced that they are making progress in the creation of human-animal chimeras with organs that could be used for transplantation, quickly sparking a debate on whether such ethically questionable work should be allowed. After turning human cells into an embryonic stem cell-like state, basically erasing their identity and turning them into a blank slate, the Japanese team coaxed them into becoming specialized cells that form cartilage. After roughly two months, the tube had dissolved and the team was left with a living ear made from human cells that, in theory, could be grafted onto patients with ear malformations or deformities resulting from injury, such as those wounded on the battlefield.Similar work was conducted just a few years ago by a team in the U.S., but instead of using human stem cells, they took tissue from cows and sheep and grew it around an ear-shaped wire frame, which was also implanted into a rat. Not Now. The result is a living human ear measuring about 2 inches long.
