>We're using tissues that were from foetuses that were aborted 40, 50, 60 years ago," Dr Lott said.
>"It doesn't require newly aborted foetuses."
>While living human cells can only divide around 50 times, those foetal cells have been genetically modified so they can divide an infinite number of times.
>"That's why we can use the cells that we harvested [decades ago] today," Dr Lott said.
>"They're not the actual original cells, they've been immortalised and then propagated over the decades."
>This means we'll never need to replace specimens used in development.
