Funded Activity Summary

The movement of epithelial cells within our body (the cells that form the thin protective layer on exposed bodily surfaces such as skin and the lining of internal cavities, ducts, and organs) is essential for our normal embryonic development as well as for healing of wounds following injury. Understanding how this movement is regulated is therefore a fundamental area of medical biology. Although much is known about the mechanics of how a cell moves, the signals used to coordinate this movement so as to ensure that each cell migrates to the right place during embryonic development or in response to a wound is not well understood. A number of lines of evidence suggest that proteins required for the correct orientation of cells within our body (a property of cells known as polarity) may be essential for this process. Mutation of the polarity protein Scribble in the fly, zebrafish and mouse causes a disorganization of epithelial tissues during embryonic development. We have now shown that Scribble is required for cells to orientate correctly so as to be able to move in response to a wound in tissue culture and also during embryonic development and wound healing in the mouse. It is currently unknown how Scribble regulates migration. Here we propose to identify the molecules that Scribble regulates to coordinate cell movement during development and tissue repair. These studies will provide new insights into the fundamental process of how cell movement is coordinated and could lead to novel strategies for improved treatment of tissue injuries.
