Abstract

SUMMARY The choroid plexus (ChP) in each brain ventricle produces cerebrospinal fluid (CSF) and forms the blood-CSF barrier. Here, we construct a single cell and spatial atlas of each ChP in the developing, adult, and aged mouse brain. We delineate diverse cell types, subtypes, cell states and expression programs in epithelial and mesenchymal cells across ages and ventricles. In the developing ChP, we predict a common progenitor pool for epithelial and neuronal cells, validated by lineage tracing. Epithelial and fibroblast cells showed regionalized expression by ventricle, starting at embryonic stages and persisting with age, with a dramatic transcriptional shift with maturation, and a smaller shift in each aged cell type. With aging, epithelial cells upregulated host defense programs and resident macrophages upregulated IL-1β signaling genes. Our atlas revealed cellular diversity, architecture and signaling across ventricles during development, maturation and aging of the ChP brain barrier.

Written from the paper’s full text.

TL;DR

This paper presents a single-cell and spatial atlas of the mouse choroid plexus across lateral, third, and fourth ventricles in developing, adult, and aged brains. It identifies ventricle- and age-dependent epithelial/mesenchymal programs, a Wnt1+ common progenitor for epithelial and neuronal cells, and aging-associated immune signaling including IL-1β.

Key findings

  • Profiled 15,620 single cells and 83,040 single nuclei from lateral, third, and fourth ventricle choroid plexuses of developing (E16.5, n = 13), adult (4 months, n = 4), and aging (20 months, n = 9) mice, defining major cell classes and subtypes across ages and ventricles.
  • Trajectory inference and lineage tracing supported a common progenitor pool for epithelial and neuronal cells; Wnt1+ progenitors near FoxJ1+ epithelial cells gave rise to both epithelial and neuronal progeny in the 4V and 3V ChP.
  • Epithelial and fibroblast cells showed ventricle-regionalized expression starting embryonically and persisting with age; maturation produced a large transcriptional shift, and aged epithelial cells upregulated host-defense programs while aged macrophages upregulated IL-1β signaling genes.
  • Mesenchymal cells expressed ACE2 and accessory SARS-CoV-2 entry components, and ligand-receptor analysis predicted mesenchymal cells as an interaction hub, with IL-1β signaling from aged macrophages to endothelial and mesenchymal cells.

Methods

  • Mouse ChP from LV, 3V, and 4V was dissected at E16.5, 4 months, and 20 months; embryonic samples were profiled by scRNA-seq, and all ages by snRNA-seq, followed by smFISH, immunostaining, transgenic lineage tracing, and whole-tissue imaging.
  • Analyses included clustering, diffusion maps, RNA velocity, topic modeling, pseudobulk differential expression, and CellPhoneDB-based ligand-receptor interaction inference across ventricles and ages.
  • Validation used marker immunostaining, RNAscope, Cx3cr1-GFP and Wnt1-CRE2::R26R-Confetti mice, electron microscopy, and published in situ hybridization data.

Limitations

  • The paper states: small tissue size required pooling samples across donors, especially for immune cells; dissection purity was limited by anatomically defined borders, particularly for 3V ChP; adult/aged cellular health led to differential processing (scRNA-seq for embryonic vs. frozen samples and snRNA-seq for adult/aged, also applied to embryonic), introducing computational comparison challenges; continuous cell-state and age transitions required topic modeling; and lowly expressed genes may be missed due to coverage depth.
  • Evident from the text: the atlas is mouse-only, and several conclusions about signaling and progenitor relationships rely on inferred trajectories and predicted ligand-receptor interactions, with validation focused on selected markers and lineages.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Rspo3 probe is labeled as Rspo1

    Minor

    The probe listed for Rspo3 is labeled "mm-Rspo1," even though a separate Rspo1 probe is listed with a different reference number. The Rspo3 probe identity is therefore inconsistent within the probe list.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
