Actin filaments labeled with fluorescent phalloidin. Actin forms the major part of the cytoskeleton - the scaffolding that holds a cell in shape. Tiled view of a mature tubule with 40x lens on Zeiss 880 confocal.

Great microscopy Ian
Yeh in Amoeboid things actin filaments polymerise ( gel ) at the leading edge extending the cell and break down at the trailing end ( sol ) contracting it in. In this view we're seeing the stable scaffold of an area that's not thinking of moving. In the other pic we've got actin filaments extending out as the cell starts to move
Awesome! Are these fibers involved in locomotion; do they contract?
