The new technique works by effectively chemically stripping the old liver down too its basic “scaffold” or exoskeleton in a process of called “decellularisation”.

Onto this frame of connective tissue and blood vessels, they then regrow the new liver using stem cells from the patient. Stem cells from embryos could also be used.

The effectively brand new liver is then transplanted back into the patient.

At the moment the technique will require donor organs but it is hoped that eventually pig’s livers or artificial scaffolds can be used instead – effectively avoiding donors altogether.
