摘要:

内耳作为听觉和平衡的核心器官,其结构精密复杂,细胞类型丰富多样。单细胞转录组测序技术 (scRNA‑Seq) 能够捕获和分析单个细胞的基因表达谱,为深入解析内耳中各种细胞类型的功能及其分子机制提供了强大的工具。本文系统回顾了2015—2024年scRNA‑Seq在内耳研究领域的重要应用,重点阐述了该技术在揭示细胞异质性、追踪内耳发育过程、探究听力损伤机制以及促进细胞再生研究等方面的重要进展。我们展望了scRNA‑Seq技术在野生哺乳动物研究中可能解决的关键科学问题,以及单细胞多组学技术在揭示哺乳动物内耳的适应性进化与分子机制方面的潜力。

Abstract:

The inner ear, as the core organ responsible for hearing and balance, possesses an intricate structure with diverse cell types. Single-cell RNA sequencing technology (scRNA-Seq) enables the capture and analysis of gene expression profiles at the individual cell level, providing a powerful tool for in-depth exploration of the functions and molecular mechanisms of the inner ear. We review the significant applications of scRNA-Seq in inner ear research from 2015 to 2024, highlighting important advances in revealing cellular heterogeneity, tracing inner ear development processes, investigating hearing loss mechanisms, and cell regeneration researches. We also discuss the potential application of scRNA-Seq technology in addressing key scientific questions in wildlife research and explore the prospects of single-cell multi-omics techniques in uncovering the adaptive evolution and molecular mechanisms of the mammalian inner ear.

Key words: Cellular heterogeneity, Hearing loss, Hair cell regeneration, Developmental biology, Adaptive evolution
