Bursts of waves drive immune system 'soldiers' toward invaders
...a that our subsequent experiments validated. "We never expected to see this sort of complex behavior within cells, but in retrospect it is an absolutely ingenious way to organize cell movement. We're getting our first glimpses that take us beyond knowing that this protein is important for cell motility ...MIT creates 3-D images of living cell
... and when you add external contrast agents you can never be sure that you haven't somehow interfered with normal cellular function, said Badizadegan.
