Dr. Charles Mok discusses using fat-derived stem cells to treat MS. The approach shows promise in slowing disease progression and modest reversal in some patients, though it cannot fully repair severed nerve fibers. Fat-derived cells may work better for relapsing-remitting MS than other stem cell types.
I don't know that we could say the same for using some other type of stem cell like bone marrow or umbilical stem cells. Most of the studies been done with fat derived stem cells, and clinically we do see improvement. We have never seen something in total reversal of their ms, but we do see people who are progressive sort of slow down their progression and maybe go backwards a little bit. There's a point where the axons in the brain, little connections, or the extension cords actually get transected in the ms, and those are probably not going to grow back. But we could get this ability to stop and maybe reverse a little bit, or relapsing, remitting, get those relapses to be less fre.
