Myo1g participates in the ability of B lymphocytes to generate membrane protrusions. (a) Representative images (63 × objective) of non-activated or LPS + IL-4 activated WT and Myo1g−/− B lymphocytes incubated two hours on Fibronectin-covered coverslips. Cells were stained with Tritc-Phalloidin, and membrane protrusions are indicated with white arrows. Scale bars 5 μm. n = 3. (b) The number of membrane protrusions and (c) their lengths were measured on at least 50 activated B lymphocytes of WT and Myo1g−/− mice in three independent experiments. They were analyzed using ImageJ software (National Institutes of Health, Bethesda, MD). Data correspond to three independent experiments. Data are presented as mean ± s.d. ****P < 0.0001.
