Scientists have successfully transplanted a bioengineered lung into a pig
> Investigators used a cocktail of sugar and detergent to get rid of all the cells and blood vessels from a lung taken from a donor pig. This left behind a support scaffold made from proteins - the lung's "skeleton" if you like.<p>If I'm reading this correctly, a donor is still needed, and the main advance is that the lung is less likely to be rejected because the cells match the recipient.
