A team from Nara Medical University in Japan has made a significant breakthrough in transfusion medicine by creating artificial blood. This synthetic blood is compatible with all blood types and can be stored at room temperature for up to two years.
The artificial red blood cells are made from hemoglobin extracted from donated blood. This hemoglobin is then encased in a synthetic shell, making the final product independent of blood type. This is especially crucial in emergencies, battlefields, and natural disasters.
Furthermore, this artificial blood can be stored for two years at room temperature and up to five years in a refrigerator, significantly exceeding the 42-day shelf life of donated blood. Clinical trials began in March 2025 to test its safety and effectiveness.
