Published Workflows
Objective: Construct a whole-mouse-brain atlas that is both molecularly defined and spatially resolved.
Why it works: The workflow combines a spatial transcriptomics assay with whole-brain transcriptomic taxonomy and a common coordinate framework so molecularly defined cell types can be placed into anatomical space.

Stages
- 1.Spatial transcriptomic atlas generation by MERFISH(functional_characterization)
This stage provides the spatially resolved measurements needed for the whole-brain atlas.
Selection: Generate spatially resolved molecular measurements across the whole mouse brain.
- 2.Integration with whole-brain scRNA-seq taxonomy(secondary_characterization)
This stage links spatial measurements to transcriptomic cell-type definitions.
Selection: Integrate spatial measurements with whole-brain scRNA-seq to assign molecularly defined cell identities.
- 3.Registration into Allen CCFv3 space(confirmatory_validation)
This stage places the atlas into a shared anatomical reference space for spatial interpretation.
Selection: Map atlas outputs into a common anatomical coordinate framework.

In this study context, MERFISH is paired with whole-brain scRNA-seq integration to assign molecularly defined cell types spatially.; used in conjunction with whole-brain scRNA-seq integration in this study context
Independent follow-up evidence is still limited. Validation breadth across biological contexts is still narrow. Independent reuse still looks limited, so the evidence base may be fragile. No canonical validation observations are stored yet, so context-specific performance remains under-specified.
