Abstract

Chondroitin sulfate proteoglycans (CSPGs) consist of chondroitin sulfate (CS) glycosaminoglycans (GAGs) and core protein and regulate the migration, axonal outgrowth, and synaptogenesis in mammalian brains. In the present study, we investigated the localization of CSPGs, the effects of sensory deprivation on the density of perineuronal nets (PNNs), and the effects of chondroitinase ABC (Chase) on the formation of barrel structures in the posterior medial barrel subfield (PMBSF). In developing mouse and rat brains, the immunoreactivity of chondroitin-6-sulfate containing proteoglycan (CS-6-PG), phosphacan, and neurocan was stronger at barrel septa as compared with barrel hollows and surrounding cortex, while the labeling of Wisteria floribunda agglutinin (WFA) was observed at barrel hollows. In adult brains, CS-6-PG-immunoreactive and WFA-labeled PNNs were observed mainly at barrel hollows of mouse, but they were seen chiefly at barrel septa of rats. Sensory deprivation of facial vibrissae reduced the number of WFA-labeled PNNs at barrel hollows but not at barrel septa. Intracerebral injection of Chase did not affect the formation of barrel structures in the PMBSF. These data indicate species-dependent heterogeneity of CSPG expression and activity-dependent formation of PNNs in the PMBSF, but CS GAGs have no crucial function in constructing the barrel structures during early postnatal development.

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.
