Ty for the areas where the spinal cord motor neurons died. According to Svendsen, the cells just sit and release GDNF. Even in animals survived survived a lot of motor neurons, we did not see the connection, which is why we did not see functional recovery explained, says Svendsen.. In the new study Wisconsin nascent brain cells were used as neural progenitor cells derived from human fetal tissue developed known to a chemical as glial derived neurotrophic factor , an agent that has been shown to protect neurons secrete known. The modified cells were then implanted in the spinal cord of rats affected with a form of ALS. – GDNF a very high affinity for motor neurons in the spinal cord, says Svendsen. Implanted implanted, the cells survive nicely. In 80 % of the animals, we saw nice maturing transplants.
Although the logical next step in the research is to try and track down, The protected motor neurons are unable to hook up with muscles, Svendsen suggests the work human clinical trials human clinical trials. – We think the cells are safe, and they do increase the survival of motor neurons, Svendsen says. It is not trivial intervention. You the spinal cord the spinal cord, and there are potential problems of the immune system, but there is nothing else for these patients. .Shortage than half of staff interviewed were well as in a open houses psychiatric unit working , the majority were female, and the average age of the 20 registered nurses been 52. Five years older than of 20 psychiatry nurse assistants.
