This video demonstrates a method to trace the origins of sensory neurons in the dura mater using fluorescence microscopy. A retrograde tracer is introduced into the exposed dura mater of an anesthetized rat. The tracer is taken up by sensory neuronal axons and travels retrogradely to their cell bodies...

Here we present a protocol to visualize spatial correlation of calcitonin gene-related peptide (CGRP)-immunoreactive nerve fibers and blood vessels in the cranial dura mater using immunofluorescence and fluorescent histochemistry with CGRP and phalloidin, respectively. In addition, the origin of these nerve fibers was retrograde traced with a fluorescent neural tracer.

FAQs
The dura mater lies directly around the brain and spinal cord, so opening it creates access while also bringing underlying neural and meningeal tissues into the operative field. Careful incision or reflection helps preserve adjacent structures and supports accurate visualization, tissue collection, or treatment delivery during cancer research procedures.
Opening the dura mater permits direct examination of tissues that can limit intervention in the central nervous system. This access allows investigators to collect tumor and surrounding samples, assess local responses, and investigate how anatomical organization affects biopsy, resection, or delivery of candidate therapies in CNS cancer models or surgical studies.
Tissue quality depends on accurate localization, controlled opening of the dura mater, and protection of nearby structures during exposure. These considerations help distinguish tumor from surrounding tissue and preserve material for analysis. Reliable sampling is particularly important when researchers compare tumor characteristics with treatment responses or adjacent meningeal and neural tissues.
This approach provides direct visualization and physical access to tissues beneath the dura mater, whereas approaches that leave the membrane intact do not offer the same direct route for biopsy, resection, delivery, or collection. In cancer research, that distinction matters when investigators need tumor or surrounding tissue rather than indirect assessment alone.
A typical workflow begins by opening the skull or vertebral canal to reach the dura mater. The membrane is then carefully incised or reflected, with attention to adjacent structures, so the underlying target becomes accessible. Researchers can subsequently visualize the site, collect tissue, perform resection, or deliver an intervention, depending on the study objective.
Once access is established, investigators may examine tumor tissue, surrounding neural tissue, or meningeal tissue. The exposed area can support direct visualization and collection of samples for analysis. This range is useful in CNS cancer research because it enables comparison between the lesion and nearby tissues that may influence interpretation of disease or treatment effects.
Dura mater access is useful when a study requires direct interaction with a central nervous system tumor or its surrounding tissues. Applications include biopsy, resection, drug delivery, tissue collection, and evaluation of treatment response. The approach therefore supports both investigations of tumor biology and development of therapies designed to address anatomical barriers.
Direct access allows researchers to obtain tumor and surrounding tissue during or after an intervention, creating material for treatment-response analysis. It can also support direct delivery of a candidate therapy and visualization of the treated site. Together, these outcomes help connect the intervention with tissue-level findings in CNS cancer research.
