Exploring Epigenetic Complexity in Regulation of Hematopoietic Stem Cells Niche: A Mechanistic Journey from Normal to Malignant Hematopoiesis.
Review in Advances in experimental medicine and biology, 2025. 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
Epigenetic regulation in hematopoietic stem cells (HSCs) research has emerged as a transformative molecular approach that enhances understanding of hematopoiesis and hematological disorders. This chapter investigates the intricate epigenetic mechanisms that control HSCs function, including deoxyribonucleic acid (DNA) methylation, histone modifications, and chromatin remodeling. It also explores the role of non-coding ribonucleic acid (RNAs) as epigenetic regulators, highlighting how changes in gene expression can occur without alterations to the DNA sequence. Epigenetic mechanisms play a pivotal in regulating HSC self-renewal and differentiation, processes essential for maintaining a balanced hematopoietic system in which lineage-specific hematopoietic stem and progenitor cells (HSPCs) pool is sustained. Recent advancements in epigenetic mapping and sequencing technologies have illuminated the dynamic epigenetic landscapes that characterize HSCs and their progeny. Numerous studies have revealed that dysregulation of epigenetic pathways is a hallmark of various hematological malignancies, including leukemias, lymphomas, and myelodysplastic syndromes. This review highlights key findings that demonstrate the impact of epigenetic abnormalities on the disruption of HSPC niches and the progression of oncogenesis in hematological malignancies. Furthermore, this chapter explores the therapeutic potential of targeting epigenetic modifications that are critical in formation and progression of hematologic malignancies. It also discusses the latest developments in epigenetic therapies, including the use of DNA methyltransferase inhibitors, histone deacetylase inhibitors, and emerging drugs targeting other epigenetic regulators. These therapies represent a promising strategy for resetting aberrant epigenetic states, potentially restoring normal hematopoiesis. Conclusively, this chapter offers a thorough overview of the current landscape and future directions of epigenetic research related to the maintenance of the HSPC niches. The insights presented here aim to contribute significantly to the field, offering a reference point for molecular approaches that enhance our understanding of hematopoiesis and its associated hematological malignancies.
