New stem cell technologies to replace animal testing in S. Korea

Summary

Stem cell technology is revolutionizing clinical trials by reducing the reliance on animal testing. South Korean researchers have developed artificial tonsils made from human stem cells, providing a more accurate model for medical testing. Additionally, a synthetic human heart chip, also created using stem cells, mimics real heart functions, enabling advanced cardiovascular research. Looking ahead, a multi-organ platform that connects organs like the liver and heart could replace animal testing altogether, offering a more ethical and precise alternative for clinical trials. These innovations promise to improve trial accuracy while reducing animal use in research.
