    Analysis of cell spreading following PTP-PEST targeting in fibroblasts. Both PTP-PEST (+/−) and (−/−) were allowed to spread on fibronectin-coated tissue culture dishes, and the number of spread cells was assayed after 10, 15, and 30 min. Phase-contrast of random fields after 10 (a and b) and 30 (c and d) min are shown for PTP-PEST (+/−; a and c) and PTP-PEST (−/−; b and d) cells. PTP-PEST (−/−) cells showed significantly higher cell spreading. A quantitative evaluation was expressed as the number of cells spread as a percentage of the total number of cells in the field (e). Average number of cells per field: 300; n = 8. Error bars represent the standard deviation of the mean. Bar, 200 μm.

    Gene targeting of the PTP-PEST suppresses fibroblast motility on the extracellular matrix fibronectin. Monolayers of each cell line were wounded (a and b) and maintained at 37°C for 24 h before fixing (c and d). The ability to migrate into the wound was monitored by phase-contrast microscopy of unstained cells which were photographed (×100). The aspect of each wound represents the typical result obtained after five independent experiments. In a chamber-type assay (e), the bottom side of the polycarbonate membrane was coated with fibronectin, and 10 5 cells were added to the top chamber. After 5 h, the cells that translocated to the bottom side of the membrane were counted and the result is shown as an average of eight fields from four independent experiments (error bars: standard deviation). PTP-PEST (−/−) cells stably overexpressing wild-type PTP-PEST were also tested by the same method. (Inset) Western blotting against PTP-PEST in the two cell lines. The band that appears represents overexpression since the antibody is known not to detect endogenous levels of PTP-PEST. Bar, 200 μm.

    Actin and focal adhesions staining in PTP-PEST (+/−) (a, b, e, and f) and (−/−) (c, d, g, and h) cells plated on fibronectin. After 20 min (a–d), there are no qualitative differences on the actin filaments, stained using a rhodamine-phalloidin conjugate (a and c) or in focal adhesions, stained with an antivinculin antibody and highlighted using a FITC-conjugated second antibody (b and d). However, when the cells were left for 3 h before fixing, the (+/−) cells became rounded (e) and only formed punctual focal adhesions at their periphery (f), whereas the (−/−) cells continued to spread, forming numerous stress fibers (g), and numerous focal adhesion plaques scattered throughout their ventral surface (h). The number of focal adhesions after 3 h in each cell was counted from photographs and the results are shown in i. Bar, 20 μm.
