Subgroup K: Bottom-Up Cell Biology

Saturday, December 8, 1:30 pm-5:30 pm
Room: 30D

Organizers: Daniel A. Fletcher, University of California, Berkeley; and Matthew C. Good, University of Pennsylvania

In vitro reconstitution of biological processes from their component molecular parts is a mainstay of biochemistry and has emerged over the last decade as a powerful tool in cell biology. Recent studies have shown that cell-like structures with micron-scale organization can be reconstituted from nanometer-scale parts by combining purified proteins and cytoplasmic extracts with cell-like boundary conditions. By identifying the necessary and sufficient conditions for assembly, these ‘bottom-up’ studies provide new mechanistic insight that complements more traditional ‘top-down’ cell biology. Rapid progress in micropatterning, microfluidics, and microfabrication, coupled with continued advancements in biochemistry and molecular biology, raise the possibility of creating more complete cellular reconstitutions that may one day rival the complexity of live cells.
