Cell migration and the mysterious role of cadherin

Fruit-fly ovaries were used in a new study to uncover how E-cadherin guides collective cell migration. According to traditional scientific dogma, E-cadherin acts like the mortar between bricks, holding cells together and preventing motility. This research team found the opposite: Cadherin is actually promoting the ability of cells to move and migrate. "It's doing it in three different ways in three different parts of the cell," the lead investigator said. "In each spot in the cell, cadherin is doing something different and all of those function together to orchestrate the movement of cells."
