Hippo-Yap Pathway Orchestrates Neural Crest Ontogenesis

Area of Science:

• Developmental Biology
• Cell Biology
• Genetics

Background:

• Neural crest (NC) cells are vital migratory stem cells in vertebrate embryogenesis.
• NC cells differentiate into diverse cell types, contributing to numerous tissues and organs.
• NC development defects are linked to human diseases like congenital heart defects and craniofacial abnormalities.

Purpose of the Study:

• To review the critical functions of the Hippo-Yap pathway in neural crest cell development.
• To elucidate the mechanisms by which Hippo-Yap influences NC induction, migration, proliferation, survival, and differentiation.
• To discuss diseases associated with Hippo-Yap pathway dysfunction in NC cells.

Main Methods:

• Literature review of recent studies on the Hippo-Yap pathway and neural crest development.
• Synthesis of current knowledge on Hippo-Yap's roles in NC cell fate determination.
• Analysis of disease-associated mechanisms involving Hippo-Yap in NC cells.

Main Results:

• The Hippo-Yap pathway plays indispensable roles in regulating neural crest cell proliferation, survival, and differentiation.
• Specific functions of Hippo-Yap in NC induction and migration are highlighted.
• Dysregulation of the Hippo-Yap pathway in NC cells contributes to various developmental disorders.

Conclusions:

• The Hippo-Yap pathway is a fundamental regulator of neural crest development.
• Further research into Hippo-Yap mechanisms is essential for understanding and treating NC-related diseases.
• This review consolidates current knowledge and suggests future research directions.
