Abstract

Significance: Neurotrophic factors are endogenous survival factors for developing neurons during their programmed cell death, and represent therapeutic candidates in several neurodegenerative diseases. Studies in the developing spinal cord suggest that neurotrophic factors promote the survival of motor neurons in a combinatorial manner. To better understand this, we systematically assayed pairwise combinations of neurotrophic factors (NTFs) on highly standardized motor neuron cultures prepared by a unique FACS technique. Our data unravel potent additivity of three neurotrophic factors due to their specific survival effects on distinct classes of motor neurons innervating different targets. Further analyses are required to better understand combinatorial NTF effects in adulthood and to define optimized NTF combinations for degenerative motor neuron diseases.

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

  • The motoneuron family includes alpha motoneurons (MNa) with relatively higher levels of Poln and Spp134, gamma motoneurons (MNg) with relatively higher levels of Esrrg and Htr1f, and preganglionic cells (PGC) expressing Gfra3, Nos1, and Fbn2.

    “The motoneuron (MN) family includes alpha motoneurons (MNa) which had relatively higher levels of Poln and Spp134, gamma motoneurons (MNg) which had relatively higher levels of Esrrg and Htr1f35, and the related preganglionic cells (PGC) which expressed Gfra3, Nos1, and Fbn236,37.”

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.
