As I understand current international patent law(which isn't much), there's a significant differnece between research on embryonic stem cells and adult stem cells.
As I understand it, an embryonic stem cell that is "created" into a therapy is patentable. Whereas an adult stem cell that is "altered" into a therapy is not. The procedure is, but not the cells themselves. As I understand it, that makes for a significant difference monetarily.
If this is the case, how much of that is behind the push for embryonic stem cell research? I have no doubt that every scientist working on this type of research wants to save people, but how many of them aren't also aware of the money?
