Here is an interesting link to a bunch of video's on the subject of stem cells in general. It is part of a medical group that offers the therapy for profit even now pre-trial in Peurto Rico but I do not post it to recommend that (I have no idea if these people are reputable and of course it is not an FDA approved therapy ---YET!) but instead I felt the videos were in fact just plain good on the subject.
There are pubmed listings-brand new-on using stems for MS. Apparently they decrease inflammation as well as invite healing in the area in question
There are a couple of others in the related links on the right also.
It is very good stuff.
