2018
This protocol describes the evaluation process of healing tendons in rats that have been injected with allogeneic platelet rich plasma (PRP) or saline solution after removing part of the Achilles tendon. The progress of tendon healing is evaluated at several time points using different types of analyses.

Cross-Sectional Research

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

2026
All animal procedures described here must be conducted in accordance with institutional animal ethics guidelines and approved by IACUC. All procedures must follow the principles of the 3Rs—Replacement, Reduction, and Refinement—and must be performed by trained personnel. New approach methodologies (NAMs) are innovative scientific approaches that generate biological data while reducing reliance on traditional vertebrate animal models. As part of the broader effort to implement the principles of...

In this video, we demonstrate the vibratome sectioning of a whole mouse kidney to obtain thin slices. These sliced tissue sections can be stored at low temperatures until further downstream analysis.
FAQs
Fixation is important because it preserves morphology before later handling. Dehydration and embedding then place the specimen in a condition with enough support for cutting, while a microtome or cryostat produces sections that expose internal structures. This sequence helps retain tissue architecture so microscopic observations reflect the sample rather than avoidable preparation changes.
Consistent section thickness improves image quality and reproducibility across a specimen. When sections are uniform, researchers can compare cellular features, tissue architecture, and spatial relationships more reliably. Inconsistent thickness can complicate interpretation by making structures appear different because of preparation variation rather than because of genuine biological differences.
Mounting places sections into a form suitable for microscopic examination, while staining enhances cellular features that may otherwise be difficult to distinguish. These steps help reveal tissue organization and support more precise assessment of morphology. Their value is greatest when section handling remains careful enough to preserve the prepared material.
Prepared sections provide access to internal structures that cannot be assessed as effectively from an intact specimen. Microscopic examination can reveal tissue architecture, cellular organization, and spatial relationships. Researchers can use these observations to compare normal and altered morphology or to connect structural patterns with developmental, pathological, or experimental changes.
In histology, sectioned specimens allow tissue architecture and cellular organization to be examined together. Developmental studies can use the same access to internal structures to follow changes in organization across biological material. Because sections support microscopic comparison, the methodology helps relate visible morphology to developmental patterns and other changes within specimens.
Researchers can compare the morphology of sectioned specimens to identify structural changes associated with disease or an experimental treatment. Examination may focus on altered tissue architecture, cellular organization, or spatial relationships. Consistent preparation is essential because reproducible sections make observed differences easier to interpret as biological effects rather than variation introduced during handling.
