Intravenous injection of bone marrow derived stem cells (MSC) in patients with spinal cord injuries led to significant improvement in motor functions, chercheurs .
For more than half of the patients, substantial improvements in key functions — such as ability to walk, or to use their hands — were observed within weeks of stem cell injection, the researchers report. No substantial side effects were reported.
The patients had sustained non-penetrating spinal cord injuries, in many cases from falls or minor trauma, several weeks prior to implantation of the stem cells. Their symptoms involved loss of motor function and coordination, perte sensorielle, as well as bowel and bladder dysfunction. The stem cells were prepared from the patients’ own bone marrow, via a culture protocol that took a few weeks in a specialized cell processing center. The cells were injected intravenously in this series, with each patient serving as their own control. Results were not blinded and there were no placebo controls.
Kocsis and Waxman stress that additional studies will be needed to confirm the results of this preliminary, unblinded trial. They also stress that this could take years. Malgré les défis, they remain optimistic.
“Similar results with stem cells in patients with stroke increases our confidence that this approach may be clinically useful,” noted Kocsis.
“The idea that we may be able to restore function after injury to the brain and spinal cord using the patient’s own stem cells has intrigued us for years,” Waxman said. “Now we have a hint, chez les humains, that it may be possible.”
