The mouse as a developmental model for cleft lip and palate research

Area of Science:

• Developmental biology
• Genetics
• Medical research

Background:

• Model organisms are crucial for understanding biological processes and human diseases.
• Mice serve as a valuable model for studying congenital malformations, including orofacial clefting.
• Similarities in lip and palate development between humans and mice, along with genetic manipulability, enhance their utility.

Purpose of the Study:

• To review the generation and utilization of mouse models in studying normal and abnormal lip and palate development.
• To highlight recent studies demonstrating the application of mouse models in cleft lip and palate research.
• To discuss the advantages and disadvantages of using mice in developmental studies.

Main Methods:

• Reviewing recent scientific literature on mouse models for orofacial clefting.
• Analyzing studies that employ genetic and experimental manipulations in mice.
• Comparing lip and palate development in human and mouse embryos.

Main Results:

• Mouse models exhibit significant anatomical and molecular similarities to human embryonic development of the lip and palate.
• Numerous mouse mutants have identified critical molecular players involved in lip and palate formation.
• These models demonstrate a complex molecular control network governing each developmental stage.

Conclusions:

• Mouse models are indispensable for dissecting the etiopathogenesis of orofacial clefting and other human diseases.
• Despite minor drawbacks, mice provide powerful tools for advancing our understanding of developmental biology.
• Continued research with mouse models promises further elucidation of the intricate molecular mechanisms underlying lip and palate development.
