A tissue dictionary to study pig histology

The tissue dictionary facilitates histological exploration of the pig tissues used in the expression atlas. The peripheral tissue samples were divided into two pieces, one for fixative and morphological verification while the other piece was snap frozen and used for RNA extraction (see assay and annotation for more details). Brain samples were retrieved from the respective hemispheres, of which one side was fixed in whole slabs and the other hemisphere was used for regional sampling and RNA extraction. The dictionary images enable morphological verification of the included tissue types and serves as a tool for training and understanding tissue histology in the pig.

The full tissue sections stained with hematoxylin-eosin (HE) are represented as high-resolution images and can be explored at different magnifications. Manual annotations of cells and structures found in respective tissue type are added for guidance. Corresponding human tissue types are available at Human Tissue dictionary.
