Abstract

Microphysiological systems (MPS) are complex in vitro tools that incorporate cells derived from various healthy or disease-state human or animal tissues and organs. While MPS have limitations, including a lack of globally harmonized guidelines for standardization, they have already proven impactful in certain areas of drug development. Further research and regulatory acceptance of MPS will contribute to making them even more effective tools in the future. This review explores the potential applications of human liver, gut, lung, and cardiac MPS in drug development, focusing on disease modeling, safety assessment, and pharmacokinetic studies. Various technical parameters and relevant endpoints for system assessment are discussed alongside challenges such as cell sourcing, reproducibility, and the integration of multiple tissues or organs. The importance of collaborative efforts between academia, industry, and regulatory agencies to develop standardized protocols and validation criteria is emphasized. With ongoing advancements and cooperative initiatives, MPS are poised to play a significant role in enhancing the predictivity and reliability of nonclinical testing, thereby transforming drug development and regulatory processes.


Plain language summary
Microphysiological systems (MPS) are advanced tools that simulate human organs and tissues on a miniature scale, offering a more reliable way to test new drugs than traditional cell cultures. This review explores the potential applications of liver, gut, lung, and cardiac MPS in drug development. The challenges with MPS, such as the lack of uniform standards, finding reliable sources of cells, ensuring consistent results across different experiments, and combining various types of tissues and organs in one system, are discussed. Collaboration among researchers, pharmaceutical companies, and regulators is emphasized for developing standardized protocols and improving MPS. Addressing the challenges through collaborative efforts will enhance the effectiveness of MPS, making them valuable tools for better drug testing and development.
