Summary

The supplied review summary explicitly mentions CLARITY for correspondence between CBV-weighted signal spread and microvascular architecture.

Usefulness & Problems

Why this is useful

CLARITY is presented as an anatomical or validation method relevant to comparing CBV-weighted signal spread with microvascular architecture. It provides structural context rather than a primary functional readout.; anatomical validation of imaging findings; relating functional signal spread to microvascular architecture; CLARITY is described as a hydrogel-based tissue transformation and clearing method for structural and molecular interrogation of intact tissues. The source summary also links it to deep imaging and repeated staining/elution.; structural and molecular interrogation of intact tissues; deep imaging of intact biological systems; repeated staining and elution in clarified tissue

Published Workflows

Structural and molecular interrogation of intact biological systems

2013

Objective: Enable structural and molecular interrogation of intact tissues through hydrogel-based tissue transformation, clearing, and downstream deep imaging.

Why it works: The source summary describes CLARITY as a hydrogel-based tissue transformation and clearing method that enables deep imaging and repeated staining/elution in intact tissues.

Stages

  1. 1.
    Hydrogel-based tissue transformation(library_build)

    The source summary identifies hydrogel-based tissue transformation as a defining part of CLARITY.

    Selection: Prepare intact tissue in a hydrogel-based transformed state for subsequent clearing and interrogation.

  2. 2.
    Tissue clearing(functional_characterization)

    The source summary describes CLARITY as a tissue-clearing method for intact tissues.

    Selection: Clear tissue to enable optical interrogation of intact systems.

  3. 3.
    Electrophoretic tissue clearing(functional_characterization)

    The web research summary explicitly describes ETC as an active lipid-removal component in the original workflow.

    Selection: Use active lipid removal as a core component of the original CLARITY workflow.

  4. 4.
    Deep imaging and repeated staining/elution(confirmatory_validation)

    High-signal source notes for the anchor paper indicate deep imaging and repeated staining/elution as core concepts.

    Selection: Interrogate clarified intact tissue structurally and molecularly after clearing.
