Mitochondria: the key hub for hematopoietic stem cell homeostasis maintenance and fate determination.
Review in Stem cell research & therapy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Hematopoietic stem cells (HSCs) constitute the pivotal cellular subset sustaining long-term hematopoietic homeostasis, characterized by robust self‑renewal and multilineage differentiation potential. Under physiological conditions, HSCs undergo stepwise differentiation through rigorously controlled regulatory networks to produce a full repertoire of mature blood cells, fulfilling basal physiological demands. Upon exposure to stress or pathological insults (e.g., bone marrow niche dysregulation), HSCs rapidly activate emergency regenerative programs to reconstitute hematopoietic function and restore systemic homeostasis. As intracellular "powerhouses" and central hubs of metabolic regulation, mitochondria exert profound regulatory effects on HSCs fate determination. The dynamic balance of mitochondrial metabolism not only furnishes HSCs with sufficient bioenergy but also generates critical metabolic intermediates; meanwhile, the fine-tuning of oxidative stress and autophagic machinery ensures mitochondrial network integrity. These biological processes are intricately intertwined, forming a complex regulatory network that profoundly modulates HSCs self-renewal, lineage commitment, and long-term hematopoietic reconstitution potential. This review systematically dissects the multi-dimensional regulatory mechanisms by which mitochondria govern HSCs, elaborates on the synergistic interactions and antagonistic effects among distinct components of the regulatory circuitry, and defines the pivotal role of mitochondria in sustaining HSCs homeostasis and orchestrating their repair responses to cellular damage. This work establishes a novel theoretical framework for devising mitochondrial-targeted interventions to sustain metabolic homeostasis in HSCs. Furthermore, it lays a solid scientific foundation for the treatment of hematological diseases and the development of precision therapeutic strategies, offering new insights into the clinical management of hematopoietic disorders.
