  • Specification of progenitor domains in the hindbrain and spinal cord relies on WNT and retinoic acid along the rostro-caudal axis and sonic hedgehog along the dorso-ventral axis.

    “Specification of the progenitor domains in the hindbrain and spinal cord relies on signaling molecules like WNT and retinoic acid (RA) secreted along the rostro-caudal axis, and sonic hedgehog (SHH) along the dorso-ventral axis”

  • Signals from the dorsal and ventral poles of the neural tube partition progenitors into 13 transcriptionally distinct domains ordered along the dorsal-ventral axis.

    “This is directed by signals that emanate from the dorsal and ventral poles of the neural tube that partition progenitors into 13 transcriptionally distinct domains that are ordered along the dorsal ventral axis”
  • The 11 neural progenitor domains (p0-p3, pMN, pd1-pd6) generate distinct classes of spinal neurons that further diversify into multiple subpopulations.

    “The 11 neural progenitor domains (p0-p3, pMN, pd1-pd6) generate distinct classes of spinal neurons that further diversify into multiple subpopulations”
  • At early developmental stages, morphogen gradients establish discrete domains of progenitor identities along the DV axis by inducing distinct TFs.

    “At early developmental stages, morphogen gradients establish discrete domains of progenitor identities along the DV axis by inducing distinct TFs (Alaynick et al., 2011; Briscoe and Small, 2015; Le Dréau and Martí, 2012).”

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.
