no said she and her colleagues are beginning new experiments to test the feasibility of marrow stromal cell transplantation to stimulate the growth of the nerve cells that are often missing from the inner ears of patients with profound hearing loss.

“Sonic hedgehog and retinoic acid are molecules found in embryonic tissues, but not in adult tissues,?said Dr. Hashino. “This suggests that treating marrow-derived stem cells with these molecules before transplantation might greatly enhance the possibility that the process would result in development of specific sensory neurons.?/p>

The research was published March 18 in the online early edition of the Proceedings of the National Academy of Sciences, and is scheduled to appear in the print edition of the journal March 29.
