Doctors injected stem cells from 8-week-old fetal tissue into the spine of a man in his early 60s who has advanced ALS, or amyotrophic lateral sclerosis. It was part of a clinical trial designed to determine whether it is safe to inject stem cells into the spinal cord and whether the cells themselves are safe (…)
This first patient in the clinical trial received several injections of stem cells into the lumbar region of the spinal cord, the area that controls leg function, because most ALS patients first lose muscle function in their legs, according to Karl Johe, Neuralstem’s chairman and chief scientific officer.
Bruijn says there have been a few other occasions outside the United States in which fetal stem cells have been injected into a patient, “but not necessarily using a very [rigorous] trial design.” She adds that there were also a couple of small studies in Italy that injected other types of stem cells into a few patients but that this is the first FDA-approved trial in the United States (…)
These particular stem cells — which came from the spinal cord of an 8-week-old fetus — are neural stem cells, which have the ability to turn into different types of nerve cells. These are not the same stem cells as the controversial human embryonic stem cells, which destroy the embryo when the stem cells are removed (…)
