To the best if my knowledge, the partipants inside of NCCN stand at 24. I do not hope for studies from all but it would be nice and is a possibility.
27 came from those 24 plus PPHM, AZN, and UTSW.
The point being the relationship adds a lot of potential researchers for (comparatively) little $$. That,.....is a very good thing IMHO. The other thing that is good is that with different groups, you have different viewpoints. Perhaps someone sees/explores a completely new direction that aids profitability down the road. Who knows.
