Coordination of Morphogenesis and Cell-Fate Specification in Development

Area of Science:

• Developmental Biology
• Biophysics
• Cell Biology

Background:

• Cell-fate specification drives tissue morphogenesis through gene expression changes.
• The reciprocal influence of tissue mechanics on cell fate is largely unexplored.

Purpose of the Study:

• To review how multicellular morphogenetic events and mechanical forces impact cell-fate specification.
• To discuss emerging techniques for measuring and manipulating mechanical signals in vivo.
• To highlight the importance of mechanical control in understanding embryonic tissue patterning.

Main Methods:

• Literature review of recent findings on the feedback of mechanical forces into cell fate specification.
• Discussion of emerging in vivo techniques for mechanical signal measurement and manipulation.

Main Results:

• Multicellular morphogenetic events and mechanical forces can feed back into gene regulatory pathways to specify cell fate.
• Emerging techniques provide new ways to study mechanotransduction during development.

Conclusions:

• Understanding the mechanical control of cell fate is crucial for a comprehensive view of embryonic development.
• Integrated study of mechanics and genetics will illuminate robust tissue patterning principles.
