Abstract

Single-cell trajectories can unveil how gene regulation governs cell fate decisions. However, learning the structure of complex trajectories with multiple branches remains a challenging computational problem. We present Monocle 2, an algorithm that uses reversed graph embedding to describe multiple fate decisions in a fully unsupervised manner. We applied Monocle 2 to two studies of blood development and found that mutations in the genes encoding key lineage transcription factors divert cells to alternative fates.

  • Cicero performs cell clustering on scATAC-seq trajectories constructed with an adaptation of Monocle 2, determines co-accessible regions within each group, and infers chromatin hubs by taking into account correlation between nearby regions.

    “Similarly, Cicero [64] performs cell clustering on scATAC-seq trajectories (constructed with an adaptation of Monocle 2 [65]), determines co-accessible regions within each of these groups and finally infers chromatin hubs by taking into account the correlation between nearby regions.”

  • Monocle2 pseudotime was strongly correlated with the maturation trajectory, with Pearson and Spearman R=0.94.

    “Monocle2 pseudotime was strongly correlated with our maturation trajectory (both pearson and spearman R=0.94).”
  • Very similar maturation trajectories were obtained using PCA or reverse graph embedding.

    “We obtained very similar trajectories using approaches based on PCA or reverse graph embedding (Extended Data Fig. 1)13”
  • Existing computational methods for predicting lineage trajectories generally rely on a priori knowledge of the starting point (and thus direction) of the inferred biological process.

    “Although a large number of computational methods for predicting lineage trajectories have been described, they generally rely upon (i) a priori knowledge of the starting point (and thus, direction) of the inferred biological process (6, 7)”

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.
