Researchers grow rat lung in lab

I wonder what method they used to generate the stem cells for this project.

They sneak into Summer Bible Camps late at night and roto-root the ovaries of all the sleeping blue-eyed blonde girls between 9 and 11 years old.
The surplus goes into cosmetics. Like Vichy ze only anti-ageing creme zat collaborates wiz your skin and Final Solution dandruff shampoo....

Could, could, but some use chemicals, proteins, retro-viruses and such to induce reversion in adult cells.

But if they used classic fetal stem cells that might go on to explain why the transplants only lasted from 45-120 minutes, due to rejection.

Everytime I turn on a TV, read a paper or log onto the internet there's always some new and wonderful drugs that just cured a disease in some rats.

I wonder why most of it never makes it to humans?

Because we won't eat the cured rats. We have to wait 17 years while they ferment them down into something they can mix with chalk, patent, press into pills and make up a pseudo-chemical name for.
The rat juice is actually effective after only 9 years fermentation but there's this growing aversion to unHoly Communist vaccinations, so they use that stuff in Africa first.
In the meantime we'll have to settle for hinges on our chest and 500 little rat lungs wired in series if we get emphysema.
