The innovation builds on the breakthrough discovery in 2006 by Shinya Yamanaka, who similarly coaxed human skin cells to revert to a pristine, embryonic state by introducing four key genes into the cells, piggybacked on viruses. However, some of those genes are known to cause cancer, which made Yamanaka's stem cells - known as induced pluripotent stem cells, or iPS cells - unsuitable for human use.

Gregory Coleman, an attorney representing the firefighters, told...
