TNC Leader Cells Are Required For Migration | Download Scientific Diagram When epithelia are injured, the remaining cells repair the epithelial sheet by migrating into and closing the open gap. in many epithelia, this happens through a coordinated cell movement driven by specialized cells called leaders. however, it is unclear how epithelial cells become leaders. Extensive in vivo and in vitro studies reveal the characteristics of leader cells, as well as the special mechanisms leader cells employ for maintaining their positions in collective migration.

Here we show that the effectiveness of the leader–follower organization is proportional to the asymmetry of traction and tension within cell clusters. by combining hydrogel micropatterning and. We show that the acquisition of migratory identity is autonomously controlled by notch signalling in tnc. high notch activity defines leaders, while low notch determines followers. moreover, cell cycle progression is required for tnc migration and is regulated by notch. Leader cells facilitate the directed migration of followers, directly by generating pulling forces and indirectly by modifying the composition and structure of the extracellular matrix. Leaders and followers exhibit reciprocal signaling and cooperate to ensure efficient movement. collective cell migrations drive morphogenesis, wound healing, and cancer dissemination. cells located at the front are considered leaders while those behind them are defined topologically as followers.

Leaders and followers exhibit reciprocal signaling and cooperate to ensure efficient movement. collective cell migrations drive morphogenesis, wound healing, and cancer dissemination. cells located at the front are considered leaders while those behind them are defined topologically as followers. Collective cell migrations are now appreciated to drive morphogenesis, wound healing, and cancer dissemination. cells located at the front are considered leaders while those behind them are defined topologically as followers. Based on the topology of migrating populations, tissue scale kinetics, called the “leader–follower” model, has been proposed for persistent directional collective movement. We here classify molecular and mechanical mechanisms of leading function in collective cell migration during morphogenesis and wound repair and discuss how these are recapitulated during collective invasion of cancer cells. Here, we review recent work on some of the main experimental models for collective cell migration, concluding that leader follower terminology may not be the most appropriate. it appears that not all collectively migrating groups are driven by cells located at the front.
