Organoid models are three-dimensional cell cultures that mimic the structure and function of organs in the human body. These models are created from stem cells or organ-specific cells and are used in research to study disease mechanisms, drug responses, and tissue development. Organoid models have the potential to revolutionize personalized medicine and drug discovery by providing a more accurate representation of human biology compared to traditional cell culture models. They are being used in a variety of research areas, including cancer, neurodegenerative diseases, and gastrointestinal disorders. Organoid models offer a powerful tool for studying complex biological processes and have the potential to advance our understanding of human health and disease.
