A significant discovery has identified a missing "gatekeeper" protein as the root cause of dry mouth in Sjögren's syndrome — a finding that could change the way the disease is treated.

Biomedical imaging with light-scattering spectroscopy (LSS) is a novel optical technology developed to probe the structure of living epithelial cells in situ without need for tissue removal.

We ask the following questions: How are cell fates determined in the embryonic surface epithelium? What cellular mechanisms govern early morphogenesis of epithelial appendages? Are they conserved ...
