Abstract

Single-cell RNA sequencing studies of differentiating systems have raised fundamental questions regarding the discrete versus continuous nature of both differentiation and cell fate. Here we present Palantir, an algorithm that models trajectories of differentiating cells by treating cell fate as a probabilistic process and leverages entropy to measure cell plasticity along the trajectory. Palantir generates a high-resolution pseudo-time ordering of cells and, for each cell state, assigns a probability of differentiating into each terminal state. We apply our algorithm to human bone marrow single-cell RNA sequencing data and detect important landmarks of hematopoietic differentiation. Palantir's resolution enables the identification of key transcription factors that drive lineage fate choice and closely track when cells lose plasticity. We show that Palantir outperforms existing algorithms in identifying cell lineages and recapitulating gene expression trends during differentiation, is generalizable to diverse tissue types, and is well-suited to resolving less-studied differentiating systems.

  • Gene expression trends along pseudotime show stepwise transcriptional progression of endodermal and endothelial lineages along pseudotime using Palantir.

    “Gene expression trends along pseudotime were calculated based on branch probabilities and generalized additive models, showing the stepwise transcriptional progression of endodermal and endothelial lineages along pseudotime using Palantir44.”

    From Cell diversity and plasticity during atrioventricular heart valve EMTs (2023) · cites this paper as [44]

    The Results section (‘The Palantir Algorithm’; page unavailable) says Palantir calculates gene-expression trends along pseudotime using generalized additive models weighted by branch probabilities. The cited paper’s lineage analyses concern hematopoiesis, not a stepwise transcriptional progression of endodermal and endothelial lineages, so it supports the method but not that specific finding.

  • TE cells were substantially further away (average diffusion distance 13.9) from ICM than EPI (0.41) or PrE (2.0).

    “Based on the average diffusion distance10,11 from the bipotent inner cell mass (ICM), TE cells were substantially further away (13.9) from ICM than either EPI (0.41) or PrE (2.0) (Extended Data Fig. 4b, Methods)”
  • Palantir models cell fate choices as continuous probabilistic processes rather than treating lineage decisions as bifurcations.

    “A key distinguishing feature of Palantir is that rather than treating lineage decisions as bifurcations, cell fate choices are modeled as continuous probabilistic processes.”
  • Palantir results are robust to the parameters used.

    “Palantir results however have been shown to be robust to these parameters10,11,”
  • The high resolution achieved by Palantir allows detailed mapping of gene expression trends and dynamics that are correlated with changes in lineage potential.

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.
