Symposium


(A small number of abstracts will be accepted)

1. "Marking 50 Years of CSF: The Evolving Role of Academic Society Journals" (Japanese)
Michiyuki MATSUDA (Kyoto University)
Hiderou YOSHIDA (University of Hyogo)
 

Cell Structure and Function, the official journal of the JSCB, was first published in 1975 and celebrated its 50th anniversary last year. Here we look back on this half-century and share our vision toward the next hundred years. What does CSF aim to achieve? At a time when many scientific journals are forced to transform their business models in the face of digitalization and open access trends, how can CSF differentiate itself? We would like to explore these questions together with all the participants.

2. "Intercellular communication in multicellular organisms" (Japanese)
Michitaka NOTAGUCHI (Kyoto University)
Mika NOMOTO (Nagoya University)
 

Plant cell is surrounded by cell wall that maintains cell shape and generates cell-specific characteristics. Due to this feature, plant intercellular communication relies on a pathway via “plasmodesmata”, a tunnel structure connecting adjacent cells, in addition to the extracellular pathway. This symposium will broaden its scope to fungi and animals, and discuss communication mechanisms in multicellular organisms.

3. "Host responses to transposons and their endogenization and transgenerational inheritance" (Japanese)
Kei-ichiro ISHIGURO (Chiba University)
 

Protein-coding regions comprise only ~2% of the human genome, whereas most sequences derive from transposable elements and endogenous retroviruses. Although long viewed as genomic parasites causing mutations and disease, transposable elements are now recognized as drivers of genome evolution and phenotypic diversity. This symposium focuses on host responses to transposable elements and on how their effects on genome structure are transmitted through the germline across generations, contributing to evolution and speciation.

4. "Autophagy expanded: decoding membrane interface biology" (Japanese)
Nobuo NODA (Hokkaido University)
Hitoshi NAKATOGAWA (Institute of Science Tokyo)
 

Phase-separation studies highlight proteins acting as functional ensembles, yet the roles of lipid ensembles remain less understood. In autophagy, proteins and lipids dynamically cooperate at membrane interfaces to drive precise, complex membrane remodeling. This symposium will present new insights into this protein–lipid “molecular concert” and its impact on autophagy and other cellular phenomena.

5. "Advances in Extracellular Vesicle Research: Visualization, Quantification, and Functional Insights" (English)
Richard Wong (Kanazawa University)
Chitose ONEYAMA (Aichi Cancer Center)
 

This symposium brings together leading researchers in extracellular vesicle (EV) biology to highlight advanced analytical technologies and their application to EV functional analysis. Topics include HS-AFM for visualizing dynamic changes on EV, phospholipid-based EV analysis, SICM and super-resolution microscopy for observing EV structure and uptake mechanisms, and quantitative evaluation of EV cargo. By integrating these approaches, the symposium aims to deepen understanding of EV action mechanisms.

co-sponsored by: Transformative research areas (A) [Mechanical self-transformation of living systems]

6. "Mechanical tuning of multicellular dynamics" (English)
Asako SHINDO (The University of Osaka)
Erina KURANAGA (Kyoto University)
 

Cell and developmental biology have shown that physical principles, coupled with chemical and physiological processes, drive the emergence and organization of living systems. Such physical and mechanochemical interactions may leave a history, in which transient physical forces are stored as lasting cellular states that shape later multicellular dynamics. In this symposium, we will discuss how multicellular systems develop, tune, and dynamically transform living organisms from diverse perspectives.

co-sponsored by: Transformative research areas (A) [EPIC Assembly]

7. "Assembly dynamics and their principles in cell functions and organization" (English)
Kazuhiro AOKI (Kyoto University)
Satoshi SAWAI (The University of Tokyo)
 

This symposium focuses on “evolutionary information assembly” as a unifying concept to understand how novel biological functions emerge through the assembly of heterogeneous components across molecular, cellular, and multicellular scales. By integrating advanced live-cell imaging, theoretical modeling, and information-based approaches, we will discuss non-equilibrium dynamics, self-organization, and functional emergence, highlighting new perspectives for cell biology beyond static component-based descriptions.

 


(A small number of abstracts will be accepted)
co-sponsored by: Transformative research areas (A) [Shin-biology regulated by protein lifetime]

8. "Cell Biology Perspective from Protein and Organelle Lifetime Regulation" (Japanese)
Shigeo MURATA (The University of Tokyo)
Yasushi SAEKI (The University of Tokyo)
 

This symposium focuses on protein and organelle lifetime regulation as a framework for understanding the relationship between intracellular degradation mechanisms and functional control. Centered on the ubiquitin–proteasome system and autophagy, we will discuss how regulated degradation is linked to membrane dynamics and cellular homeostasis. We will also share perspectives on how disruption of lifetime control mechanisms may be associated with cellular dysfunction and disease.

co-sponsored by: JST-CREST [Multicellular Interaction] Development of Technology Platforms for Quantitative Analysis of Spatiotemporal Multicellular Interaction

9. "Exploring multicellular dynamics by spatio-temporal molecular quantification" (Japanese/English)
Hirofumi SHINTAKU (Kyoto University)
Fumiko TOYOSHIMA (Institute of Science Tokyo)
 

Understanding dynamic biological systems requires the development of technologies that can comprehensively and quantitatively measure and analyze spatiotemporal interactions of multicellular systems at the molecular and cellular levels within tissues and organs. This symposium will present the latest topics in omics technologies, force measurement techniques, imaging technologies, and mathematical analysis methods, that incorporate temporal and spatial information. The symposium will also discuss how these technologies can be applied to elucidate diverse biological phenomena.
