Exo70 is recruited to the plasma membrane at sites of mechanical wounding. Exo70 is recruited to the plasma membrane at sites of mechanical wounding. NRK cells were either wounded with glass beads or left unwounded in the presence of fluorescent dextran (red), fixed, stained with DAPI (blue) and anti-Exo70 antibodies (green), and imaged. (A,B) Non-wounded cells incubated in Ca2+-free medium. (B′) Higher magnification of the region outlined in B. (C,D) Non-wounded cells incubated in Ca2+-containing medium. (D′) Higher magnification of the region outlined in D. (E,F) Cells wounded for 30 s in Ca2+-free medium. (F′) Higher magnification of the region outlined in F.
