Figure 3.
DSFs connect ventral and dorsal sides of the lamella. (A) Maximum projection and z sections every 330 nm from the box in Fig. 2 B showing the layers of actin structures at the edge. Open arrowheads and open arrows in A denote DSF and actin arcs, respectively. (B) Ventral, dorsal, and side views (taken from the yellow boxed region) of the actin filaments in a spreading primary MEF cell. Open arrowheads and open arrows in side view denote DSF and actin arcs, respectively. Bar, 10 µm.
