Scientists Create Artificial Blood

Posted by Zonk on Fri May 11, 2007 02:25 PM
from the plastics-we're-in-you dept.
simm1701 wrote us with a BBC article link on a sort of artificial blood substitute being developed by an English university. The substance is light, can survive at room temperature, and keeps longer than real blood, allowing it to be used as a stand-in in emergency situations. "The new blood is made up of plastic molecules that have an iron atom at their core, like haemoglobin, that can carry oxygen through the body. The scientists said the artificial blood could be cheap to produce and they were looking for extra funding to develop a final prototype that would be suitable for biological testing ... A sample of the artificial blood prototype will be on display at the Science Museum in London from 22 May as part of an exhibition about the history of plastics."

      Not all plastics cause the body to flip out as you describe it.

      I'd be more concerned with where they go after the emergency is over. The spleen collects dead red blood cells... do the artifical ones "die"? What happens to the plastic then?

      IANAD, so, can any harm happen with an excess of red blood cells? Maybe this will lead to a future where some could supercharge their blood to maximize oxygen carrying ability.

        That's the point of the research, I guess. The obvious advantage is that since the stuff is totally synthetic, it is guaranteed to be sterile, hence the long shelf life. But I wonder along with you about them calling the stuff 'plastic'.

        Since the functions of a red blood cell (apart from carrying oxygen) include:

        1. Preventing the haemoglobin escaping and being degraded in the blood stream
        2. Reducing the osmotic (water pulling) effect of haemoglobin if it were free
        3. Keeping the haemoglobin in the blood stream

Worst case, you get a plastic scab on a wound, but in reality, I would expect it to cause problems where you'd essentially become a hemophiliac because your blood could not coagulate. And doesn't the body already do "house cleaning" to eliminate blood periodically. What happens to all of that plastic that the body can't eliminate?

      I've heard that they did have a problem with the body's immune system flipping out and attacking the new artificial blood cells in early testing, but since they fitted each one of them with a miniature eyepatch and peg leg they've been able to defend themselves quite effectively.

        Turn-X furiously tapped away at his keyboard, sweat dripping from his brow. Time was of the essence, and he had to get his message out NOW.

        The story had just come up over the SlashWire, and unlike the usually dismissive drivel, this one caught his eye. Artificial blood. Something wasn't right here. They were going to investigate artificial blood? He thought back to his high school biology and that time he skinned his knee. Also that one program he saw on Nova. Blood...body...plastic...NO GOOD! My God, what if the body totally flipped out and went all attack mode on the blood! An emergency situation would be totally ruined!

        He had to act.

        Quickly he hit the reply button. The world needed to know before the scientists made an irreversible mistake. As fast as his fingers could go, he tapped out his response and hit sumbit. Now all he could do was wait. The story was fresh, so he might have caught it in time.

        Yes! There it was. The Slashmods had taken notice. A reply. A mod point. But not good enough...not yet. Minutes ticked by, the story was already the second down. Would he make it in time?

        Waiting...waiting...

        YES! +5 moderation! He sighed. His point was made, and now the world knew. The scientists would roll back their plans and head back to the drawing board.

        Turn-X would sleep well tonight.

    • I'm guessing the innovation here isn't that this is a plasma replacement so much as it is a way to replace blood cells, which I assume would be combined with an artificial plasma product to produce artificial "whole blood" that is typeless, free of biological contaminants and most of all able to be manufactured as needed.

    the body does attack certain polymers proteins being an example of this as in incompatible blood types and a possible solution could be to coat the compound in a coating that the body doesn't attack- like its own proteins or something along those lines like an artificial blood cell.

    There was a big stink a while back about FDA trials without consent. The problem is if your in shock and being serviced by first responders you don't really have time to fill out a consent form and the EMT's can't carry real blood with them so synthetic blood is the only option.
  • Blood substitutes [wikipedia.org] have been around for a while. I remember seeing a demonstration of perfluorocarbon based artificial blood in the early 1980s. You could also breath the stuff. Or at least, the mouse they dropped in it could. This is a differrent approach, artificial hemoglobin, but I think there have been previous versions of that as well.

    Among other things he talked about blood substitutes, describing how the day is near when you'll be able to take a single deep breath and sit on the bottom of your pool for 15+ minutes, so efficient will be your (artificially enhanced) uptake of oxygen.

    He gave a great speech. I recommend his book, "The Singularity is Near."

    My cat got very sick a few years ago after being bitten by a raccoon. When the local vet couldn't diagnose the problem we took him to the College of Veterinary Medicine [msu.edu] at Michigan State University. The cat couldn't even stand up and was fading fast so they wanted to give him a transfusion. But when they tried to match his blood type the samples reacted against every donor they checked. So they offered to try an experimental artificial blood.

    The artificial blood kept him alive long enough to identify a parasite infection, start him on treatment for the parasites, and let him recover until a natural blood donor could be found and infused. He was hospitalized for over a week but finally recovered and is perfectly healthy now. The interesting side effect is that he bulked up massively since the illness. He's over twenty pounds and extremely muscular. I don't know which artificial blood they used and what other side effects it had, but it seems like it might have more applications beyond just blood replacement for emergencies.

  • IANAD, but I have worked as a hospital chaplain.

    This is a big deal for a lot of reasons. I'd like to point out a few of the less obvious

    Jehova's Witnesses have already been mentioned, but add to this list dome forms of Judiasm, branches of Meninite Christianity, and others as divers as the Hmong [wikipedia.org] refuse blood transfusions. Artificial plasma (sometimes called artificial blood) is acceptable as are the use of cell savers. Unfortunately neither of these are effective against the uncontrolled loss of blood, or against blood based diseases that kill of red blood cells. The ability to artificially add O2 capacity and not just volume to the blood will a very welcome thing for these groups. From first hand experience being with families, I can tell you that no matter what the ultimate decision, being caught between needing blood and keeping faith is a heart breaking and guilt ridden experence for doctors, patients and families.

    The other issue I want to bring up is the trust of the blood supply. There is an unfortunate and sad history of treating minorities in the US with inferior medicine, which has included infected blood. The rumors that such practices are ongoing persist particularly in the homeless populations. My perception from talking with some of the people who believe these rumors is that artificial blood would be perceived as safer. Perception is often stronger then reality when it comes to patient compliance, and even if this remains a sub-optimal solution when compared to whole blood (my guess is this will remain the case though IANAD) it is better then refusing treatment.

    I hope that this is proven to be save and effective.
