Orientation of Actin Filaments Imaged in Live Cells (2 of 2) (VIDEO)

Marine Biological Laboratory

Caption

At left, fluorescent particles move along treadmills of actin filaments in a human skin cell. The images were added along the polarization dimension to compute total fluorescence intensity. At right, orientation of actin filaments at the location of each fluorescent particle. The orientation was computed from polarization-resolved images and is shown by the magenta line.
