Esophageal organoids from a variety of pathologies including cancer are grown in Advanced Dulbecco's Modified Eagle Medium-Nutrient Mixture F12 (hereafter ADF). However, the currently available ADF-based formulations are suboptimal for normal human esophageal organoids, limiting the ability to compare normal esophageal organoids with those representing a given disease state. We have utilized immortalized normal human esophageal epithelial cell (keratinocyte) lines EPC1 and EPC2 and endoscopic normal esophageal biopsies to generate three-dimensional (3D) organoids. To optimize the ADF-based medium, we evaluated the requirement of exogenous epidermal growth factor (EGF) and inhibition of transforming growth factor-(TGF)-β receptor-mediated signaling, both key regulators of the proliferation of human esophageal keratinocytes. We have modeled human esophageal epithelial pathology by stimulating esophageal 3D organoids with interleukin (IL)-13, an inflammatory cytokine, or UAB30, a novel pharmacological activator of retinoic acid signaling. The formation of normal human esophageal 3D organoids was limited by excessive EGF and intrinsic TGFβ-receptor-mediated signaling. Optimized HOME0 improved normal human esophageal organoid formation. In the HOME0-grown organoids, IL-13 and UAB30 induced epithelial changes reminiscent of basal cell hyperplasia, a common histopathologic feature in broad esophageal disease conditions including eosinophilic esophagitis. HOME0 allows modeling of the homeostatic differentiation gradient and perturbation of the human esophageal epithelium while permitting a comparison of organoids from mice and other organs grown in ADF-based media.
从各种病症(包括癌症)中培养的食管类器官在高级 Dulbecco 改良 Eagle 培养基-营养混合物 F12(简称 ADF)中生长。然而,目前可用的基于 ADF 的配方对正常人类食管类器官并不理想,限制了将正常食管类器官与代表特定疾病状态的类器官进行比较的能力。我们利用永生化的正常人类食管上皮细胞(角质形成细胞)系 EPC1 和 EPC2 以及内镜下正常食管活检来生成三维(3D)类器官。为了优化基于 ADF 的培养基,我们评估了外源性表皮生长因子(EGF)和转化生长因子-β(TGF)-β受体介导的信号转导抑制的需求,这两者都是人类食管角质形成细胞增殖的关键调节剂。我们通过用白细胞介素(IL)-13 或 UAB30 刺激食管 3D 类器官来模拟人类食管上皮病理学,IL-13 是一种炎症细胞因子,UAB30 是一种新型的维甲酸信号药理学激活剂。正常人类食管 3D 类器官的形成受到过度 EGF 和内在 TGFβ-受体介导的信号的限制。优化后的 HOME0 提高了正常人类食管类器官的形成。在 HOME0 生长的类器官中,IL-13 和 UAB30 诱导上皮发生变化,类似于基底细胞增生,这是包括嗜酸性食管炎在内的广泛食管疾病条件中的一种常见组织病理学特征。HOME0 允许模拟人类食管上皮的稳态分化梯度和扰动,同时允许比较在基于 ADF 的培养基中生长的来自小鼠和其他器官的类器官。
