From what I remember from Human Subjects training in my grad school days, the prison environment is considered to be so coercive that it pretty much makes "informed consent" unobtainable. While some studies are still done on prisoners, the bar to getting such a study approved is very high (or at least, is supposed to be very high). There have been indeed cases where organs were harvested without permission (not just from prisoners, either). The difference is that in the United States (and almost all other countries) this is considered to be a crime, and you go to jail if you get caught doing it.
