Revolutionary Universal Blood Created by Japanese Scientists
Discover the groundbreaking universal artificial blood that offers extended shelf life and compatibility with all blood types, promising a transformative impact on transfusion medicine.
Japanese researchers at Nara Medical University have pioneered an innovative universal artificial blood compatible with every blood type, marking a major advancement in medical science.
This breakthrough centers on extracting hemoglobin—the iron-rich protein responsible for oxygen transport—from expired blood donations. The hemoglobin is then encapsulated within synthetic protective shells, ensuring stability and eliminating the risk of viral contamination.
A standout feature of this artificial blood is its remarkable shelf life: it can be stored for up to two years at room temperature and up to five years refrigerated, far exceeding the 42-day limit of conventional donor red blood cells which require stringent storage conditions.
Initiated in 2022, the development process began with trials involving healthy volunteers aged 20 to 50. Participants received intravenous doses up to 100 milliliters of the synthetic red blood cells. While some experienced mild side effects, vital signs such as blood pressure remained steady, underscoring the treatment's safety.
Building on these promising results, researchers have since increased dosages to between 100 and 400 milliliters. Pending minimal adverse effects, the team plans to progress to comprehensive evaluations of the therapy’s effectiveness and safety.
This cutting-edge artificial blood could become a practical medical solution by 2030, revolutionizing emergency care and transfusion medicine worldwide.
