Japanese Scientists Develop Artificial Blood (www.tokyoweekender.com)

The artificial blood is created by extracting hemoglobin — a protein containing iron that facilitates the transportation of oxygen in red blood cells — from expired donor blood. It is then encased in a protective shell to create stable, virus-free artificial red blood cells. As these artificial cells have no blood type, there is no need for compatibility testing. The synthetic blood can reportedly be stored for up to two years at room temperature and five years under refrigeration.

We can't make lab hemoglobin yet?

[–] Ensign_Crab@lemmy.world 5 points 2 days ago (1 children)

They're getting the hemoglobin from expired donor blood.

So presumably, we can use real blood until it expires and then process the expired blood to extend its usefulness for up to 5 years.

This is already a massive improvement.

Any mammal blood contains hemoglobin. Think about that.

[–] Ensign_Crab@lemmy.world 5 points 1 day ago (1 children)

Damn.

They're winning the Nobel for this.

[–] Treczoks@lemmy.world 2 points 1 day ago (1 children)

If it works, it will be one of the most deserved ones.

[–] Ensign_Crab@lemmy.world 3 points 1 day ago

Agreed. Shelf-stable blood by itself is a massive win for medicine.

Shelf-stable universal donor blood from abundant sources is nothing short of a fucking miracle.

At scale it'd probably be cheapest to just gin up some yeast that produces it. They were probably using expired blood for research purposes because they had easy access

Yeah it's better to solve the blood substitute problem first. Then if it works look at better ingredient creation.
