Re-myelination from stem cells

Scientists at Case Western Reserve have found a way to persuade pluripotent stem cells to become the specific type of cell that produces myelin and to re-myelinate living mice:

Mice stem cells guided into myelinating cells by the trillions

For once, I've got no logical criticisms to make. This is brilliant work which fills me with hope for those of us dealing with demyelination and all the havoc it causes. Here's hoping it translates well into human models, and soon.
