Abstract

Not All Neurons Are Alike: As life proceeds, many cells acquire individualized mutations. In the immune system, genome rearrangements generate useful antibody diversity. McConnell et al. (p. 632 ; see the Perspective by Macosko and McCarroll ) now show that human neurons also diversify. Neurons taken from postmortem human frontal cortex tissue and neurons derived from induced pluripotent stem cell differentiation in vitro showed surprising diversity in individual cell genomes. Up to 41% of the frontal cortex neurons had copy number variations—no two alike—with deletions more common than duplications.

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

  • Early successes include parallel measurement of the transcriptome and either the genome (DR-seq and G&T-seq), the methylome (scM&T-seq, an adaptation of G&T-seq), or the proteome.

    “Early successes include parallel measurement of the transcriptome and either the genome (DR-seq209 and G&T-seq210), the methylome (scM&T-seq211, an adaptation of G&T-seq), or the proteome212–214.”
  • Emerging experimental frameworks now allow simultaneous measurement of multiple omic data types from the same single cell.

  • Somatic mutations induced by erroneous DNA damage repair or transposable elements are a common feature of neural development, giving rise to neuron diversity through genomic mosaicism.

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.
