Single-cell transcriptomics reveal individual and cooperative effects of trisomy 21 and GATA1s on hematopoiesis.
Article in Stem cell reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Trisomy 21 (T21) is associated with baseline erythrocytosis, thrombocytopenia, neutrophilia, transient abnormal myelopoiesis (TAM), and myeloid leukemia of Down syndrome (ML-DS). TAM and ML-DS blasts harbor mutations in GATA1, resulting in the exclusive expression of the truncated isoform GATA1s. Germline GATA1s mutations in individuals without T21 cause congenital cytopenias, typically without a leukemic predisposition. To dissect the developmental effects of T21 and GATA1s, we used a combination of isogenic human induced pluripotent stem cells, primary human fetal and neonatal cells, and single-cell transcriptomics to interrogate hematopoietic progenitors differing only by chromosome 21 and/or GATA1 status. Both T21 and GATA1s induced early lineage skewing, and trajectory analysis revealed that GATA1s altered the temporal regulation of lineage-specific transcriptional programs, disrupting cell proliferation and maturation irrespective of chromosomal context. These studies uncovered unexpected heterogeneity and lineage priming in early, multipotent hematopoietic progenitors and identified transcriptional and functional maturation blocks linked to GATA1s.
