类器官在器官移植领域的应用前景

Application prospects of organoids in organ transplantation

  • 摘要: 类器官技术是近年来生物医学领域最具突破性的前沿技术之一。作为组织干细胞在体外三维培养所形成的微型器官,类器官在组织结构、细胞类型和功能等方面与来源组织高度一致,为生物医学基础研究、药物研发以及临床精准医疗提供了理想模型,并在再生医学中展现出重要潜在价值。器官移植是治疗器官衰竭最有效的手段之一,但目前供者器官来源有限,无法满足患者需求,寻求合适的移植替代物是突破困境的关键。类器官可由患者自体组织构建,在多项研究中被证明具有较强的移植修复能力,且可有效规避免疫排斥反应和致瘤性等风险。本文总结了类器官技术的发展历程和主要应用方向,并就类器官在器官移植领域的应用前景和诸多挑战进行了综述和展望。

     

    Abstract: In recent years, organoid technology has become one of the major technological breakthroughs in biomedical field. As miniature organs constructed by three-dimensional culture of tissue stem cells in vitro, organoids are highly consistent with the source tissues in terms of tissue structures, cell types and functions, which serve as an ideal model for biomedical basic research, drug research and development and clinical precision medicine, and show important potential value in regenerative medicine. Organ transplantation is one of the most effective approaches to treat organ failure. However, the source of donor organs is currently limited, which could not meet the patients' needs. Identifying suitable graft substitutes is the key to breaking through the predicament. Organoids could be derived from the autologous tissues of patients. Multiple studies have demonstrated that organoids possess potent transplantation and repairing capabilities and may effectively avert the risk of immune rejection and tumorigenicity, etc. In this article, the development process and main application directions of organoid technology were summarized, and the application prospect and challenges of organoids in organ transplantation were reviewed and predicted.
