Abstract

The rostral migratory stream (RMS) is a well defined migratory pathway for precursors of olfactory bulb (OB) interneurons. Throughout the RMS an intense astroglial matrix surrounds the migratory cells. However, it is not clear to what extent the astroglial matrix participates in migration. Here, we have analyzed the migratory behavior of neuroblasts cultured on monolayers of astrocytes isolated from areas that are permissive (RMS and OB) and nonpermissive (cortex and adjacent cortical areas) to migration. Our results demonstrate robust neuroblast migration when RMS‐explants are cultured on OB or RMS‐astrocytes, in contrast to their behavior on astroglia derived from nonpermissive areas. These differences, mediated by astrocyte‐derived nonsoluble factors, are related to the overexpression of extracellular matrix and cell adhesion molecules, as revealed by real‐time qRT‐PCR. Our results show that astroglia heterogeneity could play a significant role in migration within the RMS and in cell detachment in the OB. © 2009 Wiley‐Liss, Inc.

  • Astro-TE clusters 5229 and 5230, located in the lateral ventricle bordering rostral dorsal STR, and clusters belonging to the Astro-OLF subclass (5231-5236) match the path of the RMS; the trajectory of these astrocyte clusters on the UMAP matches well with the corresponding spatial gradients.

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.
