organoid

An organoid is a tiny, simplified version of an organ grown in the lab from stem cells. These miniature structures mimic the key features and functions of real organs, such as the heart, brain, or intestine, allowing scientists to study how organs develop, how diseases affect them, and to test new treatments. Organoids are valuable because they provide a more accurate model than traditional cell cultures, helping researchers understand complex biological processes in a controlled environment, ultimately advancing medicine and personalized healthcare.
