Duke University's David Sherwood and his team are using live-cell imaging to probe living cells to see how they find their way to new tissues and organs in the body. In these time-lapse videos of an invading C. elegans anchor cell, 60 images taken over an hour show cell receptors and their associated actin filaments moving around the cell surface in search of the missing signal that will tell the cell where to go.

Once the receptors locate the signal, they stay put in the region of the cell membrane that is closest to its source.
