Functional analysis of neural crest & palate: Imaging craniofacial development

点击翻译按钮获取中文摘要

DESCRIPTION (provided by applicant): The research plan will refine and deploy a set of advanced tools for the imaging of tissue structure, gene expression domains and cellular dynamics during craniofacial development. Volumetric imaging tools will be used td create accurate 3D atlases that can be digitally dissected to permit the tissue interactions and cellular events to be better understood in the forming faces of normal, mutant and perturbed mouse and avian embryos. Molecular imaging agents, optimized for imaging intact tissues, will be employed to create atlases of the molecular correlates of these embryos. Finally, intraviral imaging tools will be used to study cell and tissue interactions as they take place, offering a view into the dynamic events that execute craniofacial development. The data will be assembled into atlases that will offer unprecedented tools for exploring the cellular, tissue and molecular correlates of craniofacial development. These atlases will be made widely available for the use of others in the Face Base consortium and the broader community of craniofacial researchers through an online resource created locally. In addition, they will be linked to other Face Base resources through established hubs, so that the data in our atlases can be used in concert with the molecular and structural data provided by other members of the consortium. The data acquisition pipeline established here in close collaboration with the laboratories of Dr. Yang Chai (University of Southern California) and Dr. Marianne Bronner-Fraser (Caltech) will create a model that can be expanded to phenotype and analyze other experimental systems.
