Abstract

Previous studies have indicated that newly formed oligodendrocytes are dynamic cells whose production, survival, and differentiation depend upon axonal influences. This study has characterized the appearance and fate of newly formed oligodendrocytes in developing rat brain. Oligodendrocytes appear in predictable locations and radially extend DM-20-positive processes that cover 80-microm domains in the cortex and 40-microm domains in the corpus callosum. These premyelinating oligodendrocytes have one of two fates: they myelinate axons or degenerate. Between 7 and 21 d after birth, approximately 20% of premyelinating oligodendrocytes identified in the cerebral cortex were degenerating. Oligodendrocytes that ensheathed axons expressed and selectively targeted proteolipid protein to compact myelin and did not degenerate. These observations support the hypothesis that axonal influences affect oligodendrocyte survival, differentiation, and expression of proteolipid protein gene products.

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

  • In the developing neocortex, approximately 20% of premyelinating OLs die between P7 and P11.

    “In the developing neocortex, ∼20% of premyelinating OLs die between P7 and P11 (Trapp et al., 1997).”

    From Oligodendrocyte Dynamics in the Healthy Adult CNS: Evidence for Myelin Remodeling (2013) · cites this paper as Trapp et al., 1997

    The Results section reports that approximately 20% of premyelinating oligodendrocytes in the developing cerebral cortex were degenerating at observations between P7 and P21. It does not establish that 20% died specifically between P7 and P11; the Discussion says the incidence of death cannot be determined without knowing how long degeneration remains detectable.

  • The appearance of PAM coincides with the onset of myelination, when many newly formed oligodendrocytes die.

    “The timing of their appearance coincides with the onset of myelination, during which large numbers of newly formed oligodendrocytes die (Barres et al., 1992; Trapp et al., 1997).”

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.
