## Abstract

This review summarizes recent advancements in imaging techniques used for the study of cilia, specialized hair-like structures projecting from the cell surfaces. Cilia play crucial roles in various biological processes, including sensory perception and cellular motility. This review highlights how innovative imaging methods, such as super-resolution microscopy and volume electron microscopy, have significantly advanced our understanding of cilia’s structure and function. These cutting-edge techniques have revealed detailed insights into the complexity of cilia architecture, underscoring their important roles in health and disease. By bridging basic research and clinical applications, this work enhances our knowledge of cilia-related disorders and provides valuable guidance for future functional investigations, potentially informing novel therapeutic strategies for cilia-related diseases.

Cilia are evolutionarily conserved, microtubule-based organelles characterized by their ultrastructures and diverse functional roles, including developmental signaling, mechanosensation, and fluid propulsion. They are widely distributed across cell surfaces and play crucial roles in cell cycle regulation and tissue homeostasis. Despite advances in studying their molecular regulation and functions, demonstrating the precise ultrastructure of cilia remains a challenge. Recent novel microscopy techniques, such as super-resolution microscopy and volume electron microscopy, are revolutionizing our understanding of their architecture and mechanochemical signaling. By integrating findings from different methodologies, this review highlights how these advances bridge basic research and clinical applications and provide a comprehensive understanding of the structural organization, functional mechanisms, and dynamic changes of cilia.
