Abstract

Cortical interneurons originate in the ganglionic eminences of the subpallium and migrate into the cortex in well-defined tangential streams. At the start of corticogenesis, two streams of migrating neurons are evident: a superficial one at the level of the preplate (PPL), and a deeper one at the level of the intermediate zone (IZ). Currently, little is known about the signalling mechanisms that regulate interneuron migration, and almost nothing is known about the molecules that may be involved in their choice of migratory stream. Here, we performed a microarray analysis, comparing the changes in gene expression between cells migrating in the PPL and those migrating in the IZ at embryonic day 13.5. This analysis identified genes, many of them novel, that were upregulated in one of the two streams. Moreover, polymerase chain reaction, in situ hybridization experiments and immunohistochemistry showed the expression of these genes in interneurons migrating within the PPL or IZ, suggesting that they play a role in their migration and choice of stream.

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

  • Interneurons are not distributed randomly between the marginal zone and subventricular zone streams.

    “Several lines of evidence suggest that interneurons do not distribute randomly across the MZ and SVZ streams.”

    From Development and Functional Diversification of Cortical Interneurons (2018) · cites this paper as Antypa et al., 2011

  • The transcriptional profiles of interneurons migrating through the marginal zone and subventricular zone are not equivalent.

    “For example, the transcriptional profile of interneurons migrating through the MZ and SVZ is not equivalent (Antypa et al., 2011), as it would be expected for a random distribution of interneurons in both routes.”

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.
