Eight years ago, doctors took nasal tissue samples and grafted them onto the spines of 20 quadriplegics. The idea was that stem cells within the nasal tissue might turn into neurons that could help repair the damaged spinal cord, and the experiment actually worked a few of the patients, who regained a little bit of sensation. But it didn’t go well for one woman in particular, who not only didn’t experience any abatement in her paralysis, but recently started feeling pain at the site of the implant. When doctors took a closer look, they realized she was growing the beginnings of a nose on her spine, New Scientist reports.
