Work out an equitable deal, and she imagines there could be major breakthroughs in just about every aspect of major trauma.

Of course, the first trick would be trying to figure out how it's happening, and what the factors are behind it - it can't be something that varies by blood type, or it wouldn't be so much who one trusts, it'd be who has the right antibody/antigen mix... though, now that she thinks about it, maybe she should ask Jay what type he is.
