After spinal transection, adult zebrafish have functional recovery by six weeks post-injury. To take advantage of larval transparency and faster recovery, we present a method for transecting the larval spinal cord. After transection, we observe sensory recovery beginning at 2 days post-injury, and C-bend movement by 3 days post-injury.

We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

Optic Nerve transection is a widely used model of adult CNS injury. This model is ideal for performing a number of experimental manipulations that target the retina globally or directly target the injured neuronal population of retinal ganglion cells.

Optic Nerve transection is a widely used model of adult CNS injury. Ninety percent of retinal ganglion cells (RGCs) whose axons are completely transected (axotomy) die within 14 days after axotomy. This model is easily amenable to experimental manipulations and highly reproducible.
FAQs
The transection plane determines how the upper lung is separated from its hilar attachments while retaining a defined anatomical relationship. Positioning the cut consistently helps researchers and clinicians handle the tissue in a controlled way, which is important when the specimen or operative field will undergo further dissection, reconstruction, resection, or transplantation-related processing.
Planning must account for the structures concentrated at the pulmonary hilum, including bronchi, blood vessels, lymphatics, and nerves. Although the cut is positioned superior to this central region, its relationship to these components remains important for interpreting anatomy and preserving relevant structures during subsequent handling or reconstruction.
Consistency comes from controlling the location and orientation of the transection plane relative to the pulmonary hilum. A standardized approach makes lung specimens more comparable across dissections or procedures and helps limit variation in how upper-lung tissue and hilar attachments are separated. This supports clearer anatomical analysis and more reproducible research or surgical outcomes.
The technique uses the hilum as an anatomical reference point rather than treating the lung as an undifferentiated mass. Because the hilum gathers airways, vessels, lymphatics, and nerves, locating the transection in relation to it allows the separated tissue to be interpreted within the lung’s structural organization and supports deliberate handling of connected components.
In lung dissection and specimen preparation, suprahilar transection provides a defined way to separate upper-lung tissue from its central attachments. This can simplify subsequent handling while preserving an interpretable relationship between the tissue and the hilum. The resulting organization is useful when researchers need to examine pulmonary anatomy or prepare material for further procedures.
The approach is relevant when lung tissue must be separated and managed during resection or transplantation-related procedures. Its value lies in establishing a controlled anatomical plane and maintaining awareness of hilar structures during subsequent handling or reconstruction. In these settings, careful positioning can help standardize processing and support consistent interpretation of the resulting surgical or experimental material.
