Yeah. I've been a part of a number of academic projects, and though my career has been in the private sector, my experience is that collaboration across fields and disciplines is relatively pain free (though maybe not a priority because the pathway to a pub and impact is not obvious). I think most people want to work with other interested people.
In my limited experience, the friction is between labs and groups that are working on very similar things, and the competition is direct and obvious. And even here, the source of the conflict is the reward structures of the field, not some aversion to collaboration or personal arrogance.
