Although stemcell research is a hot topic,could they regeneratenerve and braincells?
Answer:
Until fairly recently it was believed that we didn't produce new neurons as adults. However, we now know that the adult brain can produce new neurons. However, this is a long way from a therapeutic treatment. There is a lot of work going on using embryonic stem cells. If you go to the PubMed site and do a search for "neural stem cells" you'll get about 5600 references to current scientific work. Because different neurodegenerative diseases involve different areas of the brain and neurons with different characteristics, different types of cells will be necessary to treat different conditions. As might be expected, the nature of the particular neurodegerative disease will make certain diseases easier to treat (at least at a theoretical level). For a few conditions, such as Parkinson's disease, there is hope - but a treatment is still quite a few years out.
No.
Stemcell research is not a hot topic. Mass producing embryos to destroy for their stemcells is a hot topic.
yes, if they would let them do the research on them
just for the record, NOT all stem cells are embryonic skip-jack. Our bodies produce stem cells through our entire lives. Do some real research. And yes, that work is already in progress in medical research labs. They have already been able to repair a severed nerve in mice.
Adult stem cells have been proven to provide treatment for an abundance of diseases and injuries, but cures from these cells are still in the process of being discovered.
Embryonic stem cells, on the other hand, have promised no benefit to treatment or healing of any condition. In fact, when injected into laboratory subjects, they have caused tumors and other abnormal growths.
So as far as stem cells go, adult ones are most, and really the only, promising cells.
