Visualization of F-actin network movement in stationary keratocytes with FSM. F-actin flows centripetally from the cell periphery to the cell body in stationary cells. Video shows paired phase-contrast and AF546-phalloidin FSM time-lapse images. Phalloidin was conjugated to AlexaFluor546 for live cell FSM. Cells were imaged in culture media (Leibovitz's L-15 medium without phenol red supplemented with 14.2 mM Hepes, pH 7.4, 10% FBS, and 1% antibiotic-antimycotic). Images were acquired using an inverted microscope (Diaphot-300; Nikon) with a 60× NA 1.4 oil plan-Apo objective (Nikon). Images were acquired every 3 s with a 60× oil objective and a cooled back-thinned CCD camera (MicroMax 512BFT; Princeton Instruments) with a 2× optovar attached using MetaMorph software version 6 (Molecular Devices). 30x real time (frames were collected at 3-s intervals and are displayed at 10 frames/s). Corresponds to Fig. 1 C and Video 1 of JCB 178:1207-1221, 2007.
