Fig. 9. Overexpression of IRSp53 does not prevent Golgi polarization, but inhibits
lamellipodia formation and migration of the wound-edge NIH 3T3 cells. The
microinjected NIH 3T3 cells expressing the myc-tagged IRSp53 are shown in the
top panels of sections A, B and C. Cells were fixed at 2 hours post wounding
and labeled for Golgi (lower panel) (A) or actin (lower panel) (B). (C) Cells
were fixed at 4 hours post wounding and labeled for actin (middle panel), and
the upper and middle panels were merged and shown at the bottom. Bar, 40
µm.
