Spinal Injuries: Cell Transplant Work Moving Forward

Findings such as those reported in Toronto " represent
encouraging progress toward the development of a cure," says Robert F.
Heary, MD, who attended the AANS meeting. "In the short term, these results
have been excellent."
To confirm the potential, studies of longer duration are
needed, says Heary, a neurosurgeon at the University of Medicine and Dentistry
of New Jersey, at New Jersey Medical School in Newark. "But studies such as
this, which lend promise for the future, are spectacular," he says.
Importantly, Tator says, the potential of applying this science
in human is still years away. Overcoming things like infection and rejection as
cells are transplanted from one human to another will be a big challenge, he
"Our future studies are going to involve following these
mice for a longer period of time in a larger number of animals to see if they
can recover more. We also have plans to perform spinal cord to spinal cord
transplantation," he says. "The stem cells that originate in the spinal
cord may be more effective in regeneration than brain cells for spinal cord
Further laboratory tests of this strategy are necessary before
clinical trials in humans can be considered, Tator says.
