New to board, but here is my 2cents.
Stem cell research is about trying to replace organs / cells that no longer function the way it should, eg. your liver is no longer producing insulin, but if you get a stem cell from your body, and assuming you can transform this stem cell to whatever cell type you want, you can "make" a new liver for the sufferer. What this would mean to a drug company selling insulin would be very obvious. This is one example of how stem cell research would affect the drug industry, and a pharmicist I guess. There is probably more to it than my simple example, but the logic would apply to other situations (eg. grow a healthy heart, and do away with drugs that lower blood pressure etc...).
