Gas1-high quiescent neural stem cells are multipotent and produce oligodendrocytes during aging and after demyelinating injury.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Quiescent neural stem cells (qNSCs) in the adult mouse subventricular zone (SVZ) normally have limited capacity to generate glia. Gliogenic domains are present in both dorsal and ventral SVZ, with the ventral region featuring a subpopulation of Gli1+ qNSCs. In dorsal SVZ, however, the molecular identity and developmental origin of oligodendrogenic qNSCs remains elusive. Here, through single-cell analysis and lineage tracing, we identify an undefined subpopulation of Gas1high qNSCs in dorsal SVZ, distinct from Gli1+ qNSCs. These cells originate from embryonic Gas1high dorsal radial glia, and persist into the aged SVZ. Remarkably, they are multipotent and more gliogenic than Gas1low/- qNSCs, continuously generating oligodendrocytes in the adult and aged brain, and can be mobilized for myelin repair upon demyelination. Together, our study uncovers a subpopulation of dorsally derived, multipotent long-term qNSCs in the adult and aged SVZ with enhanced gliogenic potential, shedding light on the heterogeneity and plasticity of NSCs in normal, aging, and disease conditions.
