内耳疾病是最常见的先天性异常之一。然而,当前的组织培养模型缺乏细胞类型多样性来研究这些疾病和正常的耳发育。在这里,我们展示了人类多能干细胞衍生的内耳类器官(IEO)的稳健性,并通过单细胞转录组学评估细胞类型异质性。为了验证我们的发现,我们构建了人类胎儿和成人内耳组织的单细胞图谱。我们的研究鉴定了 IEO 中的各种细胞类型,包括周膜间质、I 型和 II 型前庭毛细胞以及发育中的前庭和耳蜗上皮。许多与先天性内耳功能障碍相关的基因已被证实在这些细胞类型中表达。 IEO 和胎儿组织内的额外细胞间通讯分析强调了内皮细胞在发育中的感觉上皮中的作用。这些发现提供了对该类器官模型及其在研究内耳发育和疾病方面的潜在应用的见解。范德瓦尔克等人。强调人类干细胞衍生的内耳类器官在研究疾病方面的潜力。单细胞转录组学鉴定了与内耳功能障碍相关的各种细胞类型,这些细胞类型在类器官和人类内耳之间共享。他们提供了一个用类器官研究遗传性内耳疾病的图谱。
Inner ear disorders are among the most common congenital abnormalities; however, current tissue culture models lack the cell type diversity to study these disorders and normal otic development. Here, we demonstrate the robustness of human pluripotent stem cell-derived inner ear organoids (IEOs) and evaluate cell type heterogeneity by single-cell transcriptomics. To validate our findings, we construct a single-cell atlas of human fetal and adult inner ear tissue. Our study identifies various cell types in the IEOs including periotic mesenchyme, type I and type II vestibular hair cells, and developing vestibular and cochlear epithelium. Many genes linked to congenital inner ear dysfunction are confirmed to be expressed in these cell types. Additional cell-cell communication analysis within IEOs and fetal tissue highlights the role of endothelial cells on the developing sensory epithelium. These findings provide insights into this organoid model and its potential applications in studying inner ear development and disorders. Van der Valk et al. highlight the potential of human stem cell-derived inner ear organoids for studying disorders. Single-cell transcriptomics identified various cell types linked to inner ear dysfunction, which are shared between organoids and the human inner ear. They offer an atlas for studying genetic inner ear disorders with organoids.
