Subgroup O: Cell Cycle Regulation of Morphogenetic Behavior 

1:30 – 5:30 pm, Room 113B
Organizers: David Q. Matus, Stony Brook University; and Benjamin L. Martin, Stony Brook University

Eukaryotic cells undergo drastic rearrangements in response to their local microenvironment. These morphogenetic changes are required for many cell biological activities, including the cell shape changes associated with cell motility and migration. Dynamic changes occur in cytoskeletal architecture between interphase and mitosis, and animal cells exhibit additional morphogenetic phenomena as they differentiate and exit the cell cycle. Traditionally, simultaneous examination of cell cycle state and cell behavior has been challenging, due to a lack of live cell cycle biosensors. For this reason, it has been difficult to unravel the relationship between cell cycle state and execution of morphogenetic behavior. However, recent advances in both imaging and cell cycle state biosensors have facilitated re-examination of cell cycle regulation during morphogenesis, the central theme of this subgroup.
