Collective cell migration is a widespread biological phenomenon, whereby groups of highly coordinated, adherent cells move in a polarized fashion. This migration mode is a hallmark of tissue morphogenesis during development and repair and of solid tumor dissemination. In addition to circulating as solitary cells, lymphoid malignancies can assemble into(More)
Cortactin is involved in invadopodia and podosome formation [1], pathogens and endosome motility [2], and persistent lamellipodia protrusion [3, 4]; its overexpression enhances cellular motility and metastatic activity [5-8]. Several mechanisms have been proposed to explain cortactin's role in Arp2/3-driven actin polymerization [9, 10], yet its direct role(More)
