You might want to have some people making bandages that can be easily cleaned and used again, because they're going to want to bite and claw at themselves. And maybe some sort of comfortable bedding and clothing for after the transformation. Clothes that are easy to get into and out of and that they can move freely in would be good, I think.
As for making the cells comfortable, there's really nothing you can do for that. They'll fight themselves and they'll bite and tear and scratch at whatever contains them to try to get out.
