Agreed. They certainly can be misleading for those who expect them to translate over to humans without a hitch.

However, if one goes into trials on mice, dogs, and other animals with the understanding that you're comparing apples to oranges, there can be a lot gained.

This approach, for instance, is something completely different than I've ever seen WRT Type 1 diabetes. It's a 180-degree approach from islet cell transplants, semi-permeable protective membranes, and immuno-suppressive drugs. As a proof of concept, I think they can probably learn a lot from it - even if they can't simply copy it to humans exactly.
