^ The whole thing is transplanted; a single piece of a kakuhou can't hold any RC cells and as such wouldn't be able to regenerate the rest of it.

Whether or not kakuhous can regenerate seems to depend on a couple of things: How bad is the damage and does the ghoul have more than one of them. If the damage is major and the ghoul only has one, the regeneration stops working permanently and the ghoul dies (Nashiro is an example of this). If the damage is minor and/or the ghoul has at least two, it heals with RC cells.

Kakuja or not, Kaneki and all the other cannibals have extra kakuhous because of cannibalism.
