Ex vivo pancreatic islet studies are important for diabetes research. Existing techniques to study cultured islets in their native 3-dimensional architecture are time consuming, inefficient, and infrequently used. This work describes a new, simple, and efficient method for generating high-quality paraffin sections of whole cultured islets.

In this video, we describe a technique of hematoxylin and eosin staining of paraffin-embedded tissue sections to study their histology. The procedure includes deparaffinization of the tissue followed by staining the cells in the tissue. Upon staining, the nucleus appears distinctly blue, and the proteins in the cytoplasm display pink coloration.
FAQs
Paraffin sectioning uses a linked preparation sequence rather than a single cutting step. Fixation, dehydration, clearing, and infiltration with molten paraffin lead to embedding in a solid block. This progression prepares the tissue for reproducible sectioning. Successful microscopic examination therefore depends on the condition of the prepared block as well as the subsequent microtome cut.
A microtome converts the solid paraffin block into thin sections suitable for microscopic examination. These sections are mounted on slides, creating a stable format for staining and observation. The cutting step makes internal cellular organization and tissue structure accessible across multiple samples, supporting consistent examination of biological specimens rather than limiting analysis to the block itself.
Sectioning produces thin tissue slices, but staining helps reveal cellular features within those slices. Once mounted and stained, the sections can be examined with light microscopy to study tissue organization. Using these steps together connects physical preparation with visual interpretation, allowing researchers to assess cellular and structural patterns that would be harder to distinguish in an unstained section.
The method provides a reproducible way to prepare preserved specimens as sections on slides. Comparable preparation can help researchers examine normal anatomy, disease-related changes, developmental features, or experimental tissue responses across samples. Because the specimens can also be retained as archival preparations, investigators may revisit material and integrate observations from different examinations over time.
Its applications include examining normal anatomy, identifying disease-related tissue changes, studying development, and evaluating experimental responses in tissues. The same preparation approach can support light-microscopic examination and histological staining, making it useful when biological questions depend on both overall tissue organization and visible cellular features in preserved specimens.
Paraffin sections can provide evidence about cellular organization and tissue structure within preserved biological samples. Depending on the research question, observations may concern normal anatomical patterns, changes associated with disease, developmental organization, or responses produced by an experiment. Staining and light microscopy help make these features visible, while archival preparation supports later comparison and review.
