3D representation of an invasive F-actin focus (middle). Horizontal confocal section reveals its invasion into the apposing founder cell (left); and vertical section reveals rings of cell adhesion molecules (Duf and Sns) enclosing the F-actin focus. The F-actin focus and the cell adhesion molecule Sns compose of a podosome-like structure (PLS) at the protruding tip of the FCM.

finger-like protrusions into the apposing founder cell.
