Single-cell analysis of mixed-lineage states leading to a binary cell fate choice
Open accessAbstract
Delineating hierarchical cellular states, including rare intermediates and the networks of regulatory genes that orchestrate cell-type specification, are continuing challenges for developmental biology. Single-cell RNA sequencing is greatly accelerating such research, given its power to provide comprehensive descriptions of genomic states and their presumptive regulators. Haematopoietic multipotential progenitor cells, as well as bipotential intermediates, manifest mixed-lineage patterns of gene expression at a single-cell level. Such mixed-lineage states may reflect the molecular priming of different developmental potentials by co-expressed alternative-lineage determinants, namely transcription factors. Although a bistable gene regulatory network has been proposed to regulate the specification of either neutrophils or macrophages, the nature of the transition states manifested in vivo, and the underlying dynamics of the cell-fate determinants, have remained elusive. Here we use single-cell RNA sequencing coupled with a new analytic tool, iterative clustering and guide-gene selection, and clonogenic assays to delineate hierarchical genomic and regulatory states that culminate in neutrophil or macrophage specification in mice. We show that this analysis captured prevalent mixed-lineage intermediates that manifested concurrent expression of haematopoietic stem cell/progenitor and myeloid progenitor cell genes. It also revealed rare metastable intermediates that had collapsed the haematopoietic stem cell/progenitor gene expression programme, instead expressing low levels of the myeloid determinants, Irf8 and Gfi1 (refs 9, 10, 11, 12, 13). Genetic perturbations and chromatin immunoprecipitation followed by sequencing revealed Irf8 and Gfi1 as key components of counteracting myeloid-gene-regulatory networks. Combined loss of these two determinants ‘trapped’ the metastable intermediate. We propose that mixed-lineage states are obligatory during cell-fate specification, manifest differing frequencies because of their dynamic instability and are dictated by counteracting gene-regulatory networks.
Overview

Written from the paper’s full text.
TL;DR
Single-cell RNA-Seq and ICGS resolved nine hierarchical myeloid states and identified prevalent and rare mixed-lineage intermediates during neutrophil-versus-macrophage specification. Irf8 and Gfi1 act as counteracting determinants of a metastable transition state that can be “trapped” by combined loss of both factors.
Key findings
- ICGS resolved nine hierarchically ordered cellular states—HSCP-1, HSCP-2, Meg, Eryth, Multi-Lin*, MDP, Mono, Gran, and Myelocyte—whose inferred developmental order agreed with the experimentally determined hematopoietic sequence.
- A prevalent Multi-Lin* state co-expressed HSCP and myeloid progenitor genes (Ctsg, Mpo, Elane) and the TFs Gata2, Meis1, PU.1, and C/EBPα, with variable priming of megakaryocytic, erythroid, granulocytic, and monocytic genes.
- Rare metastable intermediates expressed low levels of both Irf8 and Gfi1; Irf8hi GMPs were specified monocytic progenitors (CFU-M), Irf8− GMPs contained specified granulocytes (CFU-G) and bipotential progenitors (CFU-GM), and IG2s gave equal proportions of monocytic and granulocytic colonies.
- ChIP-Seq showed Irf8 peaks enriched for EICE motifs co-bound by PU.1, shared Gfi1/Irf8 regions accessible in GMPs, and increased H3K4me2 at shared regions upon Gfi1 loss or Lsd1 inhibition, correlating with enhanced monocytic potential.
Methods
- scRNA-Seq was performed on mouse LSK, CMP, GMP, and LKCD34+ cells using the C1 Single-Cell Auto Prep System; 96 LSK, 96 CMP, 136 GMP, and 66 LKCD34+ libraries were sequenced, with QC failures in 3 LSK, 2 CMP, 4 GMP, and 3 LKCD34+ samples. Additional scRNA-Seq was performed on GG1s, IG2s, and Irf8−/−Gfi1−/− GMP-like cells.
- ICGS used pairwise correlation of dynamically expressed genes and iterative clustering with pattern-specific guide genes, excluding cell-cycle genes; results were compared with six independent computational approaches and annotated using GO-Elite/ImmGen enrichment.
- ChIP-Seq for Gfi1, Irf8, and H3K4me2 was performed in GMPs, with external Cebpα ChIP-Seq and ATAC-Seq data; functional assays included CFU assays, flow cytometry, RT-PCR, and an inducible Gfi1 allele.
Limitations
- The paper does not state a formal limitations section.
- Evident from the text: the study is based on mouse bone marrow populations, and human relevance is not tested.
- Evident from the text: rare intermediates are inferred partly from population frequencies, and the Gfi1-GFP reporter expresses stable GFP, which the authors note can over-estimate Gfi1 expression and likely accounts for higher GFP in GG3s despite very low Gfi1 transcripts.

In the citing paper
“As part of the genomics revolution, increasingly accurate deep sequencing and novel methods of cell tracking have revealed hematopoiesis to be more of a continuous and less of a discrete and punctuated process than originally envisioned.”
From Unraveling Hematopoiesis through the Lens of Genomics (2020) · cites this paper as Olsson et al., 2016
In the citing paper
“Thus, while the continuum model clearly addresses some of the oversimplifications of the classic model of hematopoiesis, gene expression alone may be insufficient to distinguish discrete cell populations and may miss other relevant aspects of biology (Olsson et al., 2016).”
From Unraveling Hematopoiesis through the Lens of Genomics (2020) · cites this paper as Olsson et al., 2016
In the citing paper
“When computationally reconstructed, single-cell RNA sequencing (scRNA-seq) profiling of the mammalian hematopoietic system typically produces a largely continuous distribution of cells from the earliest HSCs through the characteristic hematopoietic lineages (Nestorowa et al., 2016; Olsson et al., 2016; Paul et al., 2015; Pellin et al., 2019; Tusi et al., 2018; Weinreb et al., 2020).”

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.
A language model drew the claims from the paper on 2026-10-10, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-10 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
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.
