Kyoto University said Friday it has conducted the world's first transplant of induced pluripotent stem cells to treat Parkinson's disease.

Nerve cells created from the artificially derived stem cells, known as iPS cells, were transplanted into the brain of a patient in his 50s in October in a treatment researchers hope to develop into a method that can be covered under Japan's health insurance system.

"By also cooperating with companies, we want to develop a mass production system that enables us to deliver nerve cells derived from iPS cells to all over the world," said Jun Takahashi, a professor at the university's Center for iPS Cell Research and Application who led the research team, at a news conference.
