With advances in stem-cell research and interest from investors, scientists are closer than ever to coming up with a substitute for blood
The coronavirus pandemic led to shortages in the blood supply across the U.S. Scientists around the world are working on a potential solution. The Future of Everything looks at the process of making artificial blood.The patient’s identity and gender are confidential, but his or her blood is at the center of an experiment that could transform medicine.
At a lab in Kyoto, Japan, scientists are running a pioneering clinical trial to treat this singular patient with a long-sought goal: artificial blood. Led by Dr. Koji Eto and a team at Kyoto University’s Center for IPS Cell Research and Application, the study aims to assess the safety and efficacy of platelets engineered in a lab out of a special type of stem cell. If successful, the research could pave the way for larger clinical trials and, ultimately, the broad use of lab-made blood.
While scientists have developed backups for most parts of our bodies—from prosthetic limbs to titanium teeth implants—the production of artificial blood has eluded them. Now, helped by advances in stem-cell research and interest from investors, scientists are closer than ever to coming up with a blood substitute., which can drop dangerously low during natural disasters or pandemics, as the U.S. saw in March.
Today, doctors and surgeons rely on blood donors for transfusions used during surgery, cancer care or following traumatic injuries. The supply must be constantly replenished. Red blood cells can be stored for 42 days, while platelets last only about five days.
