Rather than march forward in an even line like normal cells, the cells (green) in this culture careen helter-skelter toward a "scratch" (black) that represents a wound. The cells lack an enzyme called APC2, which along with 65 other proteins altered cell migration in a laboratory model of wound healing. Information on the migration effects of more than 1,000 human genes has been made freely available via a user-friendly, interactive database. The database is a valuable model for data sharing and will spur research on cell migration. Courtesy of cell biologist Joan Brugge, Harvard Medical School.
