Japan to Start Clinical Trials for Artificial Blood This Year

Japan is pioneering clinical trials for artificial blood, a breakthrough that could address global blood supply shortages. The trials, led by Nara Medical University, build on successful early-stage tests of hemoglobin vesicles—artificial blood cells proven safe and effective for oxygen delivery.

The study will administer 100 to 400 milliliters of artificial blood to assess safety before broader efficacy trials. If successful, this innovation could enter clinical use by 2030, solving critical challenges in blood donation and storage worldwide.
