>Nice scientists grew a lot of blood out of a little bit of blood.

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.

I'm curious as to what you think are possible unforseen repercussions. Genuinely, what is your opinion?

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
