在这里，我们提出了一种产生大鼠肠道类器官并将其用于几种下游应用的方案。大鼠通常是首选的临床前模型，强大的肠道类器官系统满足了对体外系统伴随体内研究的需求。

在这项研究中，我们建立了一个大鼠肠道类器官模型，该模型在长期细胞培养中具有鲁棒性。我们还展示了首次使用慢病毒感染和瞬时转染的成功基因操作。该模型是操纵大鼠肠道生物学的绝佳工具，其中体内可用的遗传工具有限。

大鼠肠道类器官以前很难长期培养。通过生成一个强大的、可遗传操作的大鼠类器官模型，我们为研究人员提供了额外的灵活性和选择，以选择最适合其特定情况的类器官模型。小鼠肠道类器官用于研究干细胞行为、细胞命运和生理学，但它们可能是一个次优模型。

由于小鼠和人类生物学之间存在关键差异。另一方面，人类肠道类器官可能难以获得，并且具有复杂的细胞培养要求。我们在这里描述的大鼠类器官模型保留了与人类生物学的关键生理相关性，同时比人类肠道类器官更容易获得和护理。

开发和优化大鼠肠道类器官模型可以进行基因操作、药物治疗和肠道生物学的更高通量研究，以及与人类具有关键生理相关性的可访问模型。此外，这些大鼠类器官将允许研究肠道中物种特异性的生理学、细胞命运、表型变异和疾病模型。
