Figure 2

Microtubules localize close to actin coats on fused secretory vesicles. ATII cells were stimulated for secretion with ATP, fixed and stained with anti-tubulin antibody, anti-ABCa3 antibody and fluorescently labelled phalloidin to label microtubules, secretory vesicles and actin coats on secretory vesicles, respectively. Cell nuclei were labelled with Hoechst 33342. Arrows in the upper row point at fused secretory vesicle that is enlarged in the bottom row. Colour overlay shows the proximity between microtubules and actin coat. Scale bar above: 10 µm, below: 2 µm.
