Description

The precise coupling of f-actin and parallel MT movements occurrs in all four zones of f-actin dynamic behavior: the lamellipodium,lamellum, convergence zone, and cell body. Primary cultures of newt (Taricha granulosa) lung epithelial cells were microinjected with X-rhodamine actin and Cy2 tubulin in coinjection. Dual-wavelength time-lapse FSM was performed on a spinning disk confocal microscope system. Light from a 50-mW Krypton-Argon ion laser (Melles Griot, OmniChrome) was delivered by a single-mode fiber optic (Point Source) to a Yokogawa spinning disk confocal scan-head (Ultra-View; PerkinElmer) on an inverted microscope (TE300 Quantum; Nikon). Excitation wavelength was selected by a filter-wheel apparatus (Sutter Instruments Co.) containing excitation filters for 488 and 568 nm (Chroma) and an opaque disk used as an excitation shutter. Emission was selected by multiple bandpass dichromatic mirror and emission filter (Chroma). Images were collected by a 100x 1.4NA Plan-Apo DIC objective lens (Nikon) and captured with an Orca 2 camera (Hamamatsu). Microscope functions were controlled by MetaMorph software (Universal Imaging). One set of sequential images of the specimen using 488 nm light for Cy2 tubulin and 568 nm light for X-rhodamine f-actin was collected in the ventral focal plane at 10s intervals. Images were processed as follows: (1) background subtraction; (2) 3 x3 low pass filter; (3) unsharp mask filter; (4) color coding MT images green and f-actin images red; and (5) color combining into 24-bit RGB images.
