Researchers have successfully grown vocal cords in a lab

Uh, so researchers have grown vocal cords... in a lab

In something that sounds completely stunning, researchers from the University of Wisconsin Medical School have published a preliminary study in the journal Science Translational Medicine, where they have successfully created 170 sets of vocal cords in a lab.

The created vocal cords don't require the normal set of immunosuppressants that normal transplants require, with study senior author Nathan Welham telling Buzzfeed: "We never imagined that we would see the impressive level of function that we did". The researchers started off with collecting cellular samples from four volunteers and one cadaver, then grew them on collagen scaffolds.

It took just two weeks for the sample cells to grow into functional vocal cords, and once they did, the researchers began testing the bioengineered larynxes by grafting them onto the kidneys of lab mice to prove the grown vocal cords wouldn't be rejected by their new hosts. These initial tests were completely successful, with the next step for the researchers is to hold longer immune response trials in mice before moving onto larger animals in the near future.

Anthony is a long time PC enthusiast with a passion of hate for games to be built around consoles. With FPS gaming since the pre-Quake days, where you were insulted if you used a mouse to aim, he has been addicted to gaming and hardware ever since. Working in IT retail for 10 years gave him great experience with high-end, custom-built PCs. His addiction to GPU technology is unwavering, and with next-gen NVIDIA GPUs about to launch alongside 4K 144Hz HDR G-Sync gaming monitors and BFGDs (65-inch 4K 120Hz HDR G-Sync TVs) there has never been a time to be more excited about technology.
