GAO：2025年人体器官芯片技术评估报告：优于动物测试但规模化遇阻存挑战（英文版）

Human organ-on-a-chip (OOC) is an emerging technology that incorporates human adult cells in a small laboratory device to mimic how organs work—such as the brain, heart, or lungs. OOCs may be designed to simulate the mechanics of human organs, such as a lung-on-a-chip that stretches to simulate breathing. Researchers are developing and using OOCs to model diseases and predict responses to chemicals. For example, companies are using OOCs to assess aspects of drug safety and efficacy. Because O
