Subgroup M: Cilia and Cell Signaling in Development and Tissue Regeneration

Saturday, December 8, 1:30 pm-5:30 pm
Room: 29B

Organizers: Peter Jackson, Stanford University; and Jeremy Reiter, University of California, San Francisco

Primary and motile cilia provide critical sensory, neuroendocrine, and metabolic control in specific tissues. Studies of the cell biology of cilia, from model systems and human ciliopathies, has led to considerable insight into ciliary function, demonstrating the importance of cilia both in early development and also in controlling degeneration of tissue in pediatric and adult settings. This regenerative role is exemplified by signaling in the Sonic Hedgehog pathway, but less well understood defects lead to liver/kidney fibrosis, airway epithelia, skin, mesenchymal tissue, brain degeneration and cancer. Here we present speakers with new understanding of signaling mechanisms and structures, the elucidation of cilia signaling pathways, and animal models reflecting the importance of cilia in stem cells, tissue regeneration, and tissue pathogenesis.
