FishFace: interactive atlas of zebrafish craniofacial development at cellular resolution

Area of Science:

• Developmental Biology
• Evolutionary Biology
• Anatomy

Background:

• Vertebrate craniofacial skeleton exhibits complexity and diversity.
• Understanding genesis and evolution requires cellular-resolution developmental programs.
• Existing resources lack integrated skeletal anatomy and cellular craniofacial development details.

Purpose of the Study:

• To create an online, 3D-interactive atlas of craniofacial development.
• To provide cellular-resolution insights into skeletal development.
• To offer analytical guidelines and suggest developmental mechanisms.

Main Methods:

• Developed the Fish Face Atlas using zebrafish (Danio rerio).
• Utilized Alizarin red-stained skulls and fluorescent optical projection tomography for 3D reconstruction.
• Integrated confocal microscopy of transgenic zebrafish to visualize cell types and morphogenesis.

Main Results:

• The atlas offers a 3D structural understanding of the zebrafish craniofacial skeleton.
• Detailed confocal images illustrate the appearance, morphogenesis, and growth of pharyngeal arch derivatives.
• High-magnification image stacks provide cellular detail for developmental and evolutionary hypotheses.

Conclusions:

• The FishFace Atlas is a novel learning tool for craniofacial skeletal development.
• Serves as a reference for comparative and mutational analyses.
• Facilitates understanding of developmental mechanisms and evolutionary insights.
