Resolving the spatial organization of fetal liver hematopoiesis by SeekSpace.
Article in Cell regeneration (London, England), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
The fetal liver is the primary site for the expansion of hematopoietic stem and progenitor cells (HSPCs) during fetal hematopoiesis. However, the spatial organization of different hematopoietic progenitor populations within the fetal liver remains poorly characterized. In this study, we utilized SeekSpace, a high-resolution single-nucleus spatial transcriptomics platform, to map the spatial distribution of hematopoietic stem cells and multipotent progenitor cells (HSC/MPPs) and downstream restricted progenitors (RPs) in relation to other hematopoietic and stromal cell populations in the fetal liver at embryonic day 13.5. Using SeekSpace, we constructed a detailed single-cell spatial transcriptomic atlas of fetal liver hematopoiesis, revealing that both HSC/MPPs and many RPs undergo active expansion in the fetal liver, a process distinct from their behavior in adult bone marrow. Proximity analysis and in situ imaging demonstrated that HSC/MPPs expansion occurs in close association with macrophages and endothelial cells throughout the fetal liver, supported by signaling pathways involving IGF and collagen. In contrast, RPs exhibited no specific spatial proximity to other cell populations during their expansion. Collectively, this study provides a comprehensive resource for understanding the spatial and molecular mechanisms underlying HSC/MPPs and RP expansion during fetal liver hematopoiesis.
