Well, I suppose the science behind it will depend on how the regrowth works, but what I'm hoping for is to find some sort of special cell, similar to an antibody, which might get to regrowing the other cells.

Otherwise, if I could get into the nucleus of the cells that are already present, extrac some information on the proteins there, then perhaps see if that can be applied to natives' bodies without the use of the nanomachines.

It's a long way off from being complete, of course, but that's because I've yet to start! I had previously been trying tho do the same thing with sea stars, but they're quite different from humans.
