Temporary effects of random positioning on the function and plasticity of proliferating monocytes.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 Random Positioning Machine (RPM) is used in the field of gravitational biology and space medicine. Rotational bioreactors such as the RPM create dynamic suspension cultures, providing shear stress, a crucial factor in circulatory homeostasis, but also in efficient mixing of nutrients and gases. This creates more physiologically relevant growth conditions than standard culture conditions translating the results to both microgravity and physiological systems on Earth. Immortalized monocyte-like THP-1 cells and primary blood-derived monocytes (PBMC) were cultured on the RPM for up to 7 days and evaluated for cell morphology, plasticity and functionality. For proliferating THP-1 cells, two different cell culture phases became obvious during random positioning: RPM early-phase (1-3 days) cells showed an increased responsiveness to lipopolysaccharide (LPS), plasticity for macrophage differentiation and phagocytic activity. RPM late-phase (4-7 days) cells demonstrated an impaired responsiveness to LPS, plasticity for macrophage differentiation and no phagocytic activity, emphasizing possible inhibitory effects of long-term random positioning on monocyte maturation and functionality. Interestingly, RPM cell culture had no significant effect on the phenotype of non-proliferating PBMCs, possibly related to their quiescence in G
