Mediterranean views on epithelial polarity.

Developmental and cell biologists viewed polarity through each other's eyes at the EMBO workshop on Epithelial Polarity in Development and Disease, March 27-31 2004, in Carry-le-Rouet, France, a small village west of Marseille on the rocky Mediterranean coast. The presentations highlighted our growing understanding, not only of the molecular mechanisms underlying polarity and the conservation of polarity complexes from worms to mammals, but also the diverse roles that epithelial polarity has during development.
