Wang et al. demonstrate that the cleavage of AMOT is essential for collective cell migration (CCM) and tumor metastasis. The cleavage of AMOT results in its spatial redistribution from apical junctions to focal adhesions (FAs), promoting leader cell formation, cell fluidization, and coherent cell migration.

The collective migration of keratinocytes during wound healing requires both the generation and transmission of mechanical forces for individual cellular locomotion as well as for the coordination of movement across cells. Leader cells initiated along the wound edge transmit mechanical and biochemical cues to ensuing follower cells, ensuring their uniform polarization …

Natural killer (NK) cells participate in the innate immune response against certain viruses, intracellular bacteria, parasites, and transformed cells (reviewed byTrinchieri 1989). Unlike B cells and T cells, NK cells do not express immunoglobulins or T cell antigen receptors, and until recently there was little insight into how these cells discriminate self from nonself. The first clue …

After the leader cell forms, the leader cell pulls on the follower cell via actin contraction, and this cell continues to migrate, causing the next cell to be pulled and to transmit further directional signals . In addition, leader cells produce higher contractile capacity than follower cells (19,94).

Hino et al. find that during collective cell migration, leader and follower cells show sustained and oscillatory ERK activation, respectively. They demonstrate that a positive feedback loop between free edge-dependent lamellipodial extension and HGF-Met-ERK activation underlies the sustained ERK activation and thereby leader cell specification.

The leader cell invades forward when the ATP/ADP ratio is high (0–160 min). As it invades, the ATP/ADP ratio drops because energy is being consumed (180–320 min). The original leader cell stops invading (340–480 min) and retracts (500–660 min) as the ATP/ADP ratio drops below a certain threshold.
