Organoid Technology as a Promising Frontier in Organ Transplantation and Regenerative Medicine

The advent of medical advances has resulted in the development of an array of treatments aimed at restoring damaged organs in humans. However, when chemical treatments, such as drug therapies, are constrained, organ transplantation may ultimately emerge as the sole viable solution. Nevertheless, despite the continually increasing demand for organ donations, the actual number of donated organs remains insufficient to meet this demand. Recently, a variety of organoids have been generated using stem cells and have been demonstrated to exhibit functionality comparable to that of native organs. This indicates that organoids may be a viable option for use in organ transplantation. However, while numerous recent publications have documented the regenerative effects of diverse organoid types when implanted into damaged regions, significant technical and ethical considerations must be addressed before organoids can be utilized as a replacement for human organs. This review presents an overview of experimental endeavors in regenerative therapies through organoid transplantation, while also addressing the challenges that must be overcome to enhance the feasibility of organoid use as a surrogate organ. As organoid technology continues to advance, organoids may eventually become a widely utilized surrogate source for organ replacement in clinical settings.
