This symposium is jointly organized by JST and KAKENHI research programs dedicated to exploring the dynamics of intracellular higher-order structures. By focusing on recent advances in structural biology, imaging technologies, and quantitative approaches for elucidating dynamic processes across multiple levels of cellular organization, we aim to share and discuss cutting-edge research with leading international scientists. Through these exchanges, the symposium seeks to promote interdisciplinary collaboration and catalyze future developments in this rapidly evolving field.
