Mapping of this cell set to the hypendemal cell type is supported by its location to the subcommisural organ (from spatial transcriptomics), its expression of Sspo and its general transcriptomic classification in a class (Astro-Epen) along with epdendymal cells, tanycytes and astrocytes.
The finest level of cell type definition in the mouse whole brain taxonomy. Cells within a cluster share similar characteristics and belong to the same supertype.
