Krebs AU - Gail A. Van Norman AB - Microphysiological systems (MPS) are complex human-based in vitro models that aim to closely replicate human (patho)physiology. This chapter explores the current state-of-the-art and limitations of organoids and organ-on-chip (OoC) systems as preeminent MPS technologies. Organoids, self-assembled 3D cellular structures, closely mimic tissue-specific architecture and functions, advancing biomedical research in disease modeling, drug discovery, and personalized medicine. Complementing organoids, OoC systems integrate microfluidics and mechanical cues to recreate dynamic biological environments, addressing organ-specific and inter-organ interactions. Key aspects of OoC systems, including design principles, cell sources, and in situ monitoring, are highlighted for their potential to model complex diseases and pharmacokinetics. Despite their promise, MPS technologies face challenges such as limited complexity, scalability, and standardization, which hinder broader application. Nevertheless, by overcoming these constraints, MPS have the potential to improve biomedical research and reduce the usage of animal models in the future.
