TOKYO: A team of Japanese scientists has developed a new kind of artificial blood that can be safely used in patients of any blood type. This discovery could be a major breakthrough in emergency care, battlefield medicine, and areas without access to proper medical facilities.

The new artificial blood is made using lab-grown red blood cells and platelets, which are wrapped in tiny synthetic bubbles. These bubbles help the artificial blood do the same jobs as real blood, like carrying oxygen and helping wounds clot. One of the biggest advantages is that it can be stored at room temperature for more than a year. Traditional blood usually needs cold storage and has a short shelf life.

This means hospitals, ambulances, and field clinics can keep this artificial blood on hand without worrying about blood type matching or refrigeration. It could save lives in car crashes, natural disasters, or war zones where fast access to compatible blood is not always possible.

The researchers say this innovation could completely change how blood transfusions are done. Instead of checking for matching blood types, doctors can quickly use this universal artificial blood. It also makes it easier to manage blood supplies in remote areas where storing and transporting real blood is difficult.

Experts believe that once approved for wider use, this new artificial blood could help millions of patients around the world. It not only simplifies the process but also reduces the risk of complications from mismatched transfusions.

Clinical trials are ongoing, and scientists are hopeful about the results. If successful, the product could become a standard item in emergency kits everywhere—from hospitals to military bases and even space missions.

Japan to Begin Clinical Trials for Artificial Blood in 2025​

Japan stands on the brink of a medical breakthrough: the development of artificial blood that could transform emergency medicine and save countless lives. But what drives this innovation, and how close are Japanese scientists to making artificial blood a reality?
A Shrinking Donor Pool and a Growing Need

For decades, Japan has faced a mounting challenge: a shrinking population and an aging society have led to fewer blood donors, even as the need for transfusions remains steady or grows. This situation is especially dire during disasters or in remote regions, where matching blood types and storing donated blood are logistical nightmares. Recognizing this, researchers have been racing to develop a safe, effective alternative-artificial blood that could be administered to anyone, anywhere, at any time.
The Science Behind the Solution

At the heart of Japan’s artificial blood efforts is a team led by Professor Hiromi Sakai at Nara Medical University. Their approach involves extracting hemoglobin-the oxygen-carrying molecule in red blood cells-from expired donor blood, then encasing it in a protective shell to create stable, virus-free artificial red blood cells. Unlike donated blood, these artificial cells have no blood type, eliminating the need for compatibility testing and making them invaluable in emergencies.
Professor Teruyuki Komatsu of Chuo University is also pioneering artificial oxygen carriers, using albumin-encased hemoglobin to stabilize blood pressure and treat conditions like hemorrhage and stroke. Animal studies have shown promising results, and researchers are eager to move to human trials.

One striking feature: the artificial blood is purple, a result of the processed hemoglobin. It’s a vivid reminder that science can look very different from what we expect-yet its function is what matters most.
From Lab to Clinic: Where Are We Now?

Japan’s artificial blood journey began with small-scale studies, like the 2022 trial of hemoglobin vesicles, which confirmed the safety and oxygen-carrying potential of these tiny artificial cells. Now, the effort is accelerating. In July 2024, Nara Medical University announced that a clinical trial involving healthy adults will begin by March 2025. The goal: to test safety and efficacy, with hopes of practical use by 2030-a timeline that could make Japan the first country in the world to deploy artificial blood for real-world medical care.

The trial will start by administering 100 to 400 milliliters of the artificial blood to volunteers. If no side effects occur, researchers will move on to broader studies. The artificial blood can be stored for up to two years at room temperature-a dramatic improvement over the less-than-one-month shelf life of donated blood.
The Human Side: Why This Matters

Behind the science are real people-patients whose lives depend on timely transfusions, doctors struggling to find compatible blood in emergencies, and families anxious for solutions during disasters. For them, artificial blood is not just a technological feat; it’s a potential lifeline. As Professor Sakai puts it, “The need for artificial blood cells is significant as there is currently no safe substitute for red cells”.

Conclusion: A Future Within Reach

Japan’s artificial blood project is more than a scientific milestone-it’s a response to a looming humanitarian need. If successful, it could set a global precedent, ensuring that blood shortages and compatibility issues no longer stand between patients and lifesaving care. The road ahead involves rigorous testing and regulatory hurdles, but the vision is clear: a world where blood is always available, for everyone, no matter the circumstance.

As Japan moves forward, the eyes of the world’s medical community-and the hopes of millions-are watching. The next chapter in transfusion medicine may soon be written in Japan, with artificial blood at its heart.

Wouldn’t this also help with lower risk spreading diseases via transfusion?

if safe this is gonna be wildly popular because if it's lowering diseases it's also removing the need to test for diseases in donated blood which will cut costs.

Unless you mean as a side benefit from lowering the frequency at which they use donated blood then no, that’s a massive lawsuit/public hazard I hope not.
