[2MS-18]【E】Revealing mechanisms of gametogenesis by live imaging

Thu. Dec 4, 2025 11:15 AM - 12:35 PM JST
Thu. Dec 4, 2025 2:15 AM - 3:35 AM UTC
Room 18(Pacifico Yokohama Conference Center 5F, 511+512)
Organizer: Masaru Ito (The University of Osaka), Yukiko Imai (Saitama University)
Gametogenesis plays an essential role in stable inheritance of genetic diversity to offsprings. Recent studies in visualizing dynamics of cells and chromosomes by imaging technologies such as live imaging reveal how each process during gametogenesis is spatially and temporally regulated. In this symposium, we introduce studies in multiple organisms and discuss mechanisms of gametogenesis.
