Eli5: Why can’t we produce “artificial” blood?

297 views

Healthcare systems depend on blood donations, which are harmless for the donors because humans usually just reproduce blood and can repeat the process over and over. What about blood is so special that we can’t manufacture it in a lab or replace is with artificial blood?

Back in the 90’s my dog got some Oxyglobin, which is “artificial blood” sorta, but my understanding is that they use cows blood to make it so it’s not uh, from scratch I guess.

Anyhow the companies attempt at a human version didn’t get any wide approval and they went under.
