tl;dr: A new study to provide blood transfusions to rare patients who have highly specific blood requirements that go beyond Blood type. The generated blood cells are made from stem cells found in blood from donors. These cells have a production rate of 1:30,000 (stem cell:red blood cell). The lab blood will be tested on healthy patients in 2 small doses over a span of 8 months. Challenges faced: stem cells blood production is not unlimited and lab production is more expensive than receiving blood donations (cost of employees, transport, etc.)

For some info: The average blood infusion is about 600 ml This translates to about 3 billion cells transfused It is unclear what type of stem cell and how much of it is derived from the blood donation. This process could be efficient/extremely inefficient.

Someone shorten this further for me

We made special blood and gave it to people. Could be good could be bad.

Can't shorten, but ELI5:

Nice scientists grew a lot of blood out of a little bit of blood. They gave this blood to people who don't have enough blood. The scientists are waiting to see if the blood they grew will help the people they gave it to.

I'd like to argue it's more like: nice scientists grew special blood from normal blood.

It's unclear how much blood they could produce from the blood they recieved. The beauty of it is that it is blood that is supposed to be more easily accepted in patients with high requirements for a blood transfusion.

Gave lab blood to humans, very expensive. Maybe cheaper some day?

Doesn't matter at the moment, they're still in the test phase seeing how it interacts with the human body, we're not even up to actual transfusions yet. They have to get over that hurdle before we're talking wide scale use so how much they can produce efficiently isn't the #1 priority right now.

If it causes anaphylactic reactions, doesn't clot or has other negative side effects it's a dead end, go back to the drawing board.
