Good to see I'm not the only one thinking this isn't all that people seem to think it is. Great, they got over the overgrowth problem, and that's huge....but the bigger one is using someone else's cells and the rejection issues that brings in-if they can take ES and make them dopamine cells, why can't they just take my cells and do the same? Oh, I forgot, they want to have a patent on the cells so they can sell them...one cell fits all, I guess.

I would think they could get a patent on the process of converting a cell into a dopamine-producing one, which would allow for individualized medicine on a person-by-person basis. Still very lucrative, and without the rejection issue(s).

I agree with the cause issue as well, these newly implanted cells may just wither as the original ones did, until they find the underlying reason why they get sick in the first place.

But like Laura said, cell replacement would at least offer an alternative to all the pills, and apparently without side effects.
