Hemoglobin made in pigs works just like human hemoglobin
Correct assembly of human normal adult hemoglobin when expressed in transgenic swine: chemical, conformational and functional equivalence with the human-derived protein.

Surprising Findings
Hemoglobin made in pigs requires no artificial modification to function like human hemoglobin.
Previous systems (like E. coli or yeast) produce misfolded or non-functional hemoglobin that must be chemically altered in the lab. The fact that pigs do it 'naturally' is a major leap forward.
Practical Takeaways
This research could inform future development of hemoglobin-based oxygen carriers (HBOCs) for transfusions.

Scientists made special pigs with human hemoglobin genes, and those pigs can actually make working human-like blood that carries oxygen and responds to body signals just like ours.
Hemoglobin made in genetically modified pigs works just like human hemoglobin without needing lab chemicals to fix it, but when it's made in bacteria or yeast, it does need extra chemical tweaks to work right.
If a lab-made protein is almost exactly like one found in nature, experts might say it’s safe enough that it doesn’t need extra testing.
Hemoglobin made in genetically modified pigs works just like the real thing from humans — it's built right, behaves the same, and carries oxygen the way it should, no lab fixes needed.
