The latest "What Is" on Scientific Frontline
What Is: Organoid
The "What Is" for this week on Scientific Frontline is not merely a definition of a biological entity but an exploration of a technological platform that bridges the chasm between the petri dish and the patient. An organoid is defined by its capacity for self-organization, a phenomenon where cells, driven by intrinsic genetic instructions and extrinsic microenvironmental cues, spatially arrange themselves into tissue-specific structures such as intestinal crypts, cortical layers, or renal nephrons.
