Collective migration modes in development, tissue repair and cancer

Area of Science:

• Cell Biology
• Developmental Biology
• Cancer Biology

Background:

• Collective cell migration is essential for tissue development, repair, and cancer metastasis.
• Cells often migrate in groups, maintaining neighbor contact, a process known as collective migration.
• Understanding collective migration is key to comprehending tissue morphogenesis and disease progression.

Purpose of the Study:

• To review the mechanisms of coordinated movement and directional sensing in collectively migrating cells in vivo.
• To compare collective migration during development and cancer, identifying shared principles and distinct cancer cell strategies.
• To highlight emergent properties of collective migration not seen in single cells.

Main Methods:

• Review of existing literature on collective cell migration.
• Analysis of in vivo studies on cell coordination and guidance cues.
• Comparative analysis of developmental and cancer collective migration paradigms.

Main Results:

• Collective migration involves leader/follower cell roles, cell-cell adhesion, signaling, and external guidance cues.
• Shared principles govern collective cell movement across different physiological contexts.
• Cancer cells employ unique dispersal strategies within collective migration.

Conclusions:

• Collective migration exhibits emergent properties, providing robustness for efficient cell movement.
• Understanding these mechanisms is vital for both developmental biology and cancer research.
• Further research into collective migration can inform therapeutic strategies for cancer metastasis.
