Source: Kirchner, K.N., et al., A Hydrophobic Tissue Clearing Method for Rat Brain Tissue. J. Vis. Exp. (2020).This video demonstrates the method of hydrophobic tissue clearing of a rat brain tissue sample. The sample is sequentially dehydrated in methanol, treated with a dichloromethane and methanol mixture to dissolve lipids and pigments, and transferred to dibenzyl ether for complete tissue clearing, enabling detailed imaging without thin sectioning.

Isolating primary microglia from the cellular heterogeneity of the brain is essential to investigate their role in both physiological and pathological conditions. This protocol describes a mechanical isolation and mixed cell culture technique that provides high yield and high purity, viable primary microglial cells for in vitro study and downstream applications.
FAQs
Fixation serves as the preservation step before Rat brain tissue is sectioned. By treating the sample before thin-section preparation, researchers maintain material that can be examined with stains or molecular labeling methods. This sequence supports consistent microscopic visualization of neurons, glial cells, brain regions, and cellular changes across samples.
Stains and molecular labeling are complementary rather than interchangeable. Stains help visualize cellular and regional features in prepared sections, whereas molecular labeling methods provide another way to examine features in the tissue. Selecting between them, or using both, helps align visualization with the specific neuroscience question being studied.
Microscopic examination of prepared sections can address several levels of organization, including individual neurons, glial cells, larger brain regions, and cellular changes associated with an experimental condition. This range allows researchers to examine anatomy and tissue responses together, linking visible patterns to questions about neural circuits, development, injury, or disease.
Researchers can examine prepared tissue from different experimental groups using comparable visualization approaches, then evaluate differences in cellular changes or tissue features. This design is useful when testing drugs or other interventions because microscopy provides a way to assess how experimental conditions relate to neural cells, brain regions, or broader tissue responses.
A basic workflow begins by preserving the sample through fixation, followed by preparing thin sections of the tissue. Researchers then apply stains or molecular labeling methods and examine the sections under a microscope. Each stage prepares the material for the next, allowing observations of neurons, glial cells, regions, and cellular changes.
Researchers use this tissue when they need to investigate nervous system structure, function, or disease in a controlled mammalian model. Applications include studying neuroanatomy, neural circuits, development, injury, and neurological disorders. Prepared sections also support evaluation of cellular responses to drugs or other interventions, connecting experimental conditions with observable tissue changes.
