Abstract
Organoid technology, as a revolutionary biomedical tool, has shown immense potential in haematological research in recent years. By using three-dimensional (3D) cell culture systems constructed from pluripotent stem cells (PSCs) or adult stem cells (ASCs), organoids can highly mimic the characteristics of in vivo organs, thereby offering significant potential for investigating human organ development, disease processes and treatment strategies. This review introduces the development of organoids and focuses on their progress in haematological research, including haematopoietic-related organoids, immune-related organoids and organoids used for studying blood system diseases. It discusses the prospects, challenges and future outlook of organoids in the field of haematology. This review aims to provide the latest advancements and future directions of organoid technology in haematological research, offering references and insights into further exploration in this field.
