The retrograde flow of microtubules oriented perpendicular to the leading edge in the lamellipodium is coupled to the movement of immediately adjacent lamellum f-actin speckles. Primary cultures of n...

The retrograde flow of microtubules oriented perpendicular to the leading edge inthe lamellipodium is not coupled to the movement of immediately adjacent lammellipodium. Primary cultures of newt (Tar...

Comparison of actin speckle microscopy with phalloidin staining. Primary cultures of newt lung epithelial cells were microinjected with X-rhodamine actin. Time-lapse FSM was performed on a spinning ...

Early transmission electron micrographs showing pore details in negatively stained preparations of nuclear envelopes. Upper panel shows the pronounced 8-fold symmetry in the closely spaced pores of t...

The precise coupling of f-actin and parallel MT movements occurrs in all four zones of f-actin dynamic behavior: the lamellipodium,lamellum, convergence zone, and cell body. Primary cultures of newt ...

Four general zones of f-actin movement are seen in primary cultures of newt lung epithelial cells microinjected with X-rhodamine actin. At the leading edge and throughout the lamellipodium, f-actin s...
