[WS08]Intra-cellular dynamics in zygotes and early embryos[J]

Thu. Jul 17, 2025 9:00 AM - 10:15 AM JST
Thu. Jul 17, 2025 12:00 AM - 1:15 AM UTC
Room C(5F Small Hall2)
Chairpersons:Tomomi Kiyomitsu(OIST), Azusa Inoue(RIKEN IMS)
During early development, intracellular components such as chromatin, nucleus, and cytoskeleton show dynamic remodeling. Recent advances in various technologies have enabled us to visualize and quantify these intracellular dynamics with high spatiotemporal precision, revealing some of the unique mechanisms of fertilized eggs and early embryos. In this workshop, we would like to introduce cutting-edge research using different perspectives, technologies, and organisms, and provide an opportunity to discuss the functional relationship between different cellular components and new research directions.
