The results of more speculative stem cell studies are starting to show up these days - one sign of increasing funding. This is an interesting one, reported at the National MS Society: "[adult mouse neural stem cells] injected into the blood of mice with MS-like disease were able to suppress the immune attacks that damage the brain and spinal cord tissues. ... These surprising findings, if confirmed, suggest that neural stem cells that reside in the adult brain may not only serve as replacement cells for tissue repair, but in some circumstances may also protect the brain from inflammation. Further research is needed to confirm these results and to address multiple issues involved in translating such experiments into finding ways to fight the immune attack and protect and repair brain tissues."
