Two ways to move together: Force coordination in collective chemotaxis.

Key Points

• The aim is to investigate how neural crest clusters achieve directed movement during collective chemotaxis.
• Analyzed the dynamics of epithelial-like neural crest clusters during movement.
• Examined the redistribution of polarity and contractility forces at cell junctions.
• Utilized experimental observations to reveal internal traction force mechanisms.
• Neural crest clusters utilized a junction-centered strategy for force coordination.
• This approach improved directed movement compared to the peripheral polarity approach.
• The findings suggest that internal force redistribution is key in collective chemotaxis.
