Hematopoietic stem cells suppress proliferation and enhance differentiation of leukemia cells through regulating apoptotic and inflammatory genes.
Article in Journal of cancer research and clinical oncology, 2023. 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
purposeStem cells are known to play an important role in tumor treatment and many of them have shown tumor-suppressing ability in different cancers; however, whether hematopoietic stem cells (HSCs) have growth-inhibiting effects on leukemia cells has not been fully evaluated. Herein, we aimed to demonstrate the growth-restraining function of HSCs in acute leukemia treatment.
methodsCell fusion experiment was conducted by PEG-1500. The viability, proliferation, apoptosis and differentiation of leukemia cells were evaluated by cell counting, CCK-8 and flow cytometry analysis. The morphological changes were imaged using a fluorescence microscope. The expression of genes was detected by quantitative reverse transcription PCR (qRT-PCR).
resultsWe observed that HSCs and their lytic extracts had the capability to suppress leukemia cells proliferation, promote apoptosis and especially induce acute myelogenous leukemia (AML) cells differentiation, which might have an effect on differentiation therapy to leukemia especially AML treatment. The expression levels of Bcl-2, Survivin decreased and Bax increased following HSCs extracts treatment. Furthermore, the expression of inflammatory cytokines also changed in AML cells which might have to do with the mechanism of HSCs/extracts suppressing effect.
conclusionHSCs and their extracts can suppress the proliferation of leukemia cells and enhance the differentiation of AML cells and using the extracts of HSCs might be a probable therapeutic option for acute leukemia.
