Neurons derived from radial glial cells establish radial units in neocortex

Abstract

The neocortex of the adult brain consists of neurons and glia that are generated by precursor cells of the embryonic ventricular zone. In general, glia are generated after neurons during development, but radial glia are an exception to this rule. Radial glia are generated before neurogenesis and guide neuronal migration. Radial glia are mitotically active throughout neurogenesis, and disappear or become astrocytes when neuronal migration is complete. Although the lineage relationships of cortical neurons and glia have been explored, the clonal relationship of radial glia to other cortical cells remains unknown. It has been suggested that radial glia may be neuronal precursors, but this has not been demonstrated in vivo. We have used a retroviral vector encoding enhanced green fluorescent protein to label precursor cells in vivo and have examined clones 1-3 days later using morphological, immunohistochemical and electrophysiological techniques. Here we show that clones consist of mitotic radial glia and postmitotic neurons, and that neurons migrate along clonally related radial glia. Time-lapse images show that proliferative radial glia generate neurons. Our results support the concept that a lineage relationship between neurons and proliferative radial glia may underlie the radial organization of neocortex.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Pyramidal excitatory neurons born in the ventricular and subventricular zones of prefrontal subdomains migrate radially toward the cortical plate under the influence of Fgfs.

    “The pyramidal excitatory neurons born in the VZ and SVZ of the prefrontal subdomains, similar to other cortical areas, start to migrate radially toward the proper position in the CP under the influence of Fgfs [50, 59, 60].”

    From Development of prefrontal cortex (2022) · cites this paper as [50]

  • After symmetric divisions, radial glia divide asymmetrically, generating postmitotic excitatory neurons that migrate to their final location in the cerebral cortex by using the basal process of the radial glial cell as a scaffold.

    “After this period of symmetric divisions, these progenitor cells — also known as radial glia — divide asymmetrically, generating postmitotic excitatory neurons that will migrate to their final location in the cerebral cortex by using the basal process of the radial glial cell as a scaffold55–58.”

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.
