The control of cell motility during embryogenesis

Area of Science:

• Developmental Biology
• Cell Biology
• Embryology

Background:

• Morphogenesis establishes complex tissue and organ organization during development.
• Morphogenetic movement, involving cell or tissue translocation, is vital in multicellular animals.
• Active cellular locomotion is a critical component of many morphogenetic movements.

Purpose of the Study:

• To review selected instances of morphogenetic movement.
• To discuss current understanding of the regulation of embryonic cell motility.
• To highlight progress in defining mechanisms of active embryonic cell migration.

Main Methods:

• Review of existing literature on morphogenetic movements.
• Analysis of characterized instances of cell migration in embryonic development.
• Discussion of regulatory processes governing cell motility.

Main Results:

• Embryonic cell migration is characterized by high precision in timing, pathways, and final localization.
• Several processes potentially important for regulating cell motility have been identified and characterized.
• Significant progress has been made in understanding the mechanisms of active embryonic cell migration.

Conclusions:

• Regulation of active embryonic cell migration is a complex but advancing area of experimental biology.
• Further research into specific instances of morphogenetic movement will enhance understanding of cell motility control.
• Defining these regulatory mechanisms is essential for comprehending developmental processes.
