Wound Healing Assay Time series DIC images of mouse DA3 cells, derived from the mouse mammary adenocarcinoma cell line D1-DMBA-3, induced in BALB/C mice by dimethylbenzanthracene were grown to 90% confluence. A scratch approximately 300um wide was made in the cell monolayer, and images were recorded every 14.5 min for 26 hr. This time series image, obtained with HGF/SF treatment, is part of a group of 17 time series images (CIL:43401 to CIL:43417) representing three different treatments: (1) no HGF/SF (CIL:43406 to CIL:43411), (2) with HGF/SF (CIL:43401 to CIL:43405), activating HGF/SF-Met signaling, and (3) with PHA (Met inhibitor) and HGF/SF (CIL:43412 to CIL:43417). The group also includes two movies (CIL:43418 and CIL:43419) created from the time series CIL:43402 and CIL:43406 respectively.
DA3 cells expressing the fluorescent protein mCherry were grown to 90% confluence in wells of 2 cm diameter in DMEM supplemented with 10% heat-inactivated FCS (Gibco-BRL) and treated with or without the Met inhibitor PHA665752 (2.5 µM) for 2 hrs. A scratch was generated using a 200 µl tip, and the cells were incubated with or without 80 ng ml-1 Met-Hepatocyte Growth Factor/Scatter Factor (HGF/SF) and subjected to time lapse confocal laser scanning microscopy (CLSM-510, Zeiss, Germany) for approximately 26 hrs, with images taken at 14.5 min intervals. The position of each scratch was predefined, and a macro that repetitively positions the microscope on each point was executed. The acquired differential interference contrast (DIC) channel of the time-lapse sequence (shown here) was used for the multi-cellular analysis; the red fluorescence channel was exploited for single cell tracking.
