Diverse roles of cell polarity in development

Sat. Jun 22, 2024 1:00 PM - 3:30 PM JST
Sat. Jun 22, 2024 4:00 AM - 6:30 AM UTC
Room C(Miyako Messe(B1F)/Special Exhibition Hall(A))
Chairpersons:Chieko Koike(Ritsumeikan Univ.), Kazunori Sasaki(Juntendo Univ.)
Cell polarity, an asymmetric distribution of cellular and molecular components along an axis, plays a fundamental role in various aspects of development and its dysfunction causes developmental defects. In this symposium, we would like to introduce and discuss the latest advances in diverse roles of cell polarity and their regulatory mechanisms during tissue morphogenesis and cell fate controls. The topics are wide-ranging, including different model organisms and systems such as nematode oogenesis, fly midgut homeostasis, frog thyroid gland morphogenesis, and mouse retinal cell fate determination. This symposium will be a valuable opportunity for participants and offer profound insights into the extensive biological significance of cell polarity in development.
