Bob,
The 2.4 million is for Dr Freedman's trial - to allow the researchers to continue their work (not sure if more patients will be treated). Given that to date it appears to have stopped MS / allowed some repair, I'd say this is worth funding. Might not become a widespread treatment but may well answer many questions.

The bonemarrow is where the scientists get the cells to be transplanted.

I think we need to wait until the results of the various trials start reporting. This is a cutting edge science and no-one knows how things will pan out. Prof Scolding's work is based on lots of lab research etc. The pilot trial is primarily to test safety. But it is encouraging that other trials of stem cells and MS are happening in humans with the disease not mice. And the stem cells treatments underway for other conditions e.g. repairing eyes / heart tissue etc must have a read across.
