About the atlas

Glass histology slides have long been the standard for analysis of normal, mutant, and disease microanatomy. Recent advancements in microscopy, computation, and the internet have made possible exciting new ways to share the data residing on traditional glass slides. With the introduction of slide scanning technologies, glass slides can be imaged in their entirety and saved as virtual slides in computer databases. This has set the stage for the creation of online histology atlases that enable users from around the world to share slide data.

Virtual slide technology enables users to view high-resolution imagery with a significantly reduced download time. Virtual slides are panned and magnified in a manner similar to a traditional microscope but offer constant context with respect to the remainder of the slide, labeling, comparison, and collaborative possibilities beyond the limitations of physical microscopy.

This atlas was originally constructed primarily for zebrafish and human tissues. We are seeking partners to help us find and share internationally unique slide collections that are in danger of being lost. We invite ideas and involvement from scientific and medical individuals and communities to make available unique and compelling slide collections. To this end we encourage and seek discussion with members of the scientific community for the benefit of society.

The following are the component atlases under current construction:

Zebrafish virtual slides:
The first goal was to provide infrastructure for service as a central repository for digital histological sections of normal and abnormal zebrafish tissue that allows progressive magnification and labeling in a manner that is coordinated with existing anatomical and phenotypic ontologies. The next goals for this project are to plan for scanning of slide collections, and to customize the database structure to a more scalable format.
Human and other virtual slides:
The second goal, which may become a primary goal, was to obtain slides from human anatomy and pathology for comparison with data from other model organisms. A subgoal was to establish post slides from other model systems.
MicroCT:
We are using the zebrafish to pursue the goal of 3D imaging of whole, mm-scale organisms (and later, specimens) for phenomics, the high-throughput study of phenotype. Accordingly, we have pursued a form of X-ray tomography in micron scale with cellular resolution. Using synchrotron microCT, we have created a 3-dimensional version of histology for zebrafish we are calling Pan-Cellular Tissue Tomography (PANCETTO). Our goal is to generate reconstructions from which the full animal can be visualized from 2D slices in any direction. This work is a collaboration with the La Riviere laboratory at University of Chicago and physicists at the Advanced Photon Source of Argonne National Laboratory.
