Clonal relations in the mouse brain revealed by single-cell and spatial transcriptomics
Open accessAbstract
The mammalian brain contains many specialized cells that develop from a thin sheet of neuroepithelial progenitor cells. Single-cell transcriptomics revealed hundreds of molecularly diverse cell types in the nervous system, but the lineage relationships between mature cell types and progenitor cells are not well understood. Here we show in vivo barcoding of early progenitors to simultaneously profile cell phenotypes and clonal relations in the mouse brain using single-cell and spatial transcriptomics. By reconstructing thousands of clones, we discovered fate-restricted progenitor cells in the mouse hippocampal neuroepithelium and show that microglia are derived from few primitive myeloid precursors that massively expand to generate widely dispersed progeny. We combined spatial transcriptomics with clonal barcoding and disentangled migration patterns of clonally related cells in densely labeled tissue sections. Our approach enables high-throughput dense reconstruction of cell phenotypes and clonal relations at the single-cell and tissue level in individual animals and provides an integrated approach for understanding tissue architecture.

YS-derived microglia persist throughout adulthood and display proliferation and self-renewal potential.
“YS-derived microglia persist throughout adulthood displaying considerable proliferation and self-renewal potential 4,5 .”
From Clonal hematopoiesis-associated motoric deficits caused by monocyte-derived microglia accumulating in aging mice (2025) · cites this paper as [5]
The Main section reports that microglia arise from a limited number of progenitors that undergo massive clonal expansion, and the Results describe their early embryonic origins. The Discussion links large clone sizes to proliferation during CNS colonization, but it does not establish that yolk-sac-derived microglia self-renew or retain considerable proliferative potential throughout adulthood.

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.
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.
