Abstract

Remyelination occurs in demyelinated CNS regions in diseases such as multiple sclerosis. Identification of the cell type(s) responsible for this remyelination, however, has been elusive. Here, we examine one potential source of remyelinating oligodendrocytes-immature, cycling cells endogenous to adult white matter-and demonstrate that this population responds to demyelination by differentiating into myelinating oligodendrocytes. Dividing cells in subcortical white matter of adult rats were labeled by stereotactic injection of a replication-deficient lacZ-encoding retrovirus (BAG). Following a focal demyelination induced with lysolecithin, many of the BAG-labeled cells differentiated into myelinating oligodendrocytes engaging in repair of the lesion. Identification of endogenous cells capable of remyelination provides a target for the study of CNS repair processes in demyelinating diseases.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Remyelination is associated with proliferation and differentiation of oligodendrocyte precursor cells into mature oligodendrocytes.

    “Importantly, however, a multitude of experimental evidence has shown that remyelination is associated with proliferation and differentiation of oligodendrocyte precursor cells into mature oligodendrocytes”

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.
