It is likely going to be a net negative for society as I doubt that any information of value can be derived from this sort of experiment in humans. There is still a lot of animal research that has to be done before human trials can bring anything useful to the table. To my knowledge, chronic renal failure isn't even close to being treatable usign stem cells in rats or any other model animal.

It is likely that the team of "scientists" in this case are a bunch of phonies with know comprehension of the basic science behind stem cells, or any serious training in research.
