Federal regulators have cleared the way for the first human trials of human embryonic stem-cell research, authorizing researchers to test whether the cells are safe to use in spinal injury patients, the company behind the trials announced Friday.
Embryonic stem cells are blank cells found in embryos, which have the ability to turn into any cell in the body.

The tests could begin by summer, said Dr. Thomas Okarma, president and CEO of the Geron Corporation. The Food and Drug Administration has approved the trials, which will use human stem cells authorized for research by then-President George W. Bush in 2001.
The patients will be those with the most severe spinal cord injuries, called complete spinal cord injuries.
