These were then seeded into ear-shaped tubing that was implanted under the skin of a growing rat and left to grow. Scientists at the University of Tokyo and Kyoto University took human cells and grew them in an ear-like shape with a mold. Evidently there have been significant developments in the field of regenerative medicine, but among this progress are ethical issues that also need to be considered. Thought to affect up to five in every 10,000 live births in the U.S., treatment often involves reconstruction using cartilage from the patients’ ribs or a synthetic implant called Medpor, a less invasive option. While the former is technically living and therefore should be able to grow and heal with the child, up to five painful surgeries are needed to complete the graft, which can leave the patient with a deformity in their chest.So although there are several options for affected individuals, evidently there is room for improvement. And it’s not just ears that scientists have set their sights on: Kidneys from aborted fetuses have also been grown in lab rodents, as well as a functioning thymus from mouse embryos.

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. The role of animals in medical laboratories is expanding in interesting ways. Yes, a rat. Email or Phone: Password: Forgot account? A human ear derived from stem cells grown on the back of a lab rat. 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. Their findings might pave the way for human trials in around 5 years’ time; there might be hope for people with birth defects or disfigurements. See more of Divine Diva Skin Care on Facebook.

Accessibility Help. The ambitious group from the University of Tokyo and Kyoto University has also claimed to the media that human trials could begin in just five years. 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. 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. Frank Wojciechowski. They weren’t photoshopped, but the ear was actually made from cow cartilage – no human tissue was involved. 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.
