> Hufford says there’s reason to think that the organs won’t grow indefinitely in the lymph nodes. The mini organs rely on chemical distress signals from the failing liver to grow; once the new organs have stabilized blood filtering, they will stop growing because that distress signal disappears, he says. But it’s not yet clear precisely how large the mini-livers will become in humans, he adds.

Well that looks promising, hopefully they stay as mini-livers.
