Functional lab-grown vocal cord tissue

Posted by BioCoM Executive Account on November 24, 2015 at 9:25 PM

Scientists at the University of Wisconsin-Madison have been able to grow a functional vocal cord tissue in the laboratory. This is a very exciting step forward that may help people who have vocal cord injuries.

After isolating cells from the vocal cords of a cadaver and the larynxes of several people who do not have cancer, the cells grew to become strong connective tissue. This system resembles how we grow artificial skin in the laboratory.

The scientists then tested if the artificial vocal cord could transmit sound. They verified this by attaching the tissue to the larynges of cadaver dogs, which were attached to artificial windpipes and had air blown in them.

Although there are many more years of research to be done before clinical applications can begin, this bioengineered vocal cord will help guide many future advancements in the field of voice impairments.
