The effects of preosteoblast-derived exosomes on macrophages and bone in mice.
Article in Journal of cellular and molecular medicine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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 effect of preosteoblast-derived exosomes on bone marrow macrophages (BMMΦ) and calvarial osteoblasts (cOB) was evaluated in vitro, and bone formation studies were performed in vivo in mice. Preosteoblastic MC3T3-E1 clone 4 (MC4) cell-derived exosomes (MC4exo) were characterized with particle tracking, transmission electron microscopy and western blot analysis to validate size, number, shape and phenotypic exosome markers. Exosomes pre-labelled with PKH67 were incubated with BMMΦ and phagocytosis of exosomes was confirmed. To examine the effect of MC4exo on macrophage polarization, BMMΦ were treated with MC4exo and the expression of pro- and anti-inflammatory cytokines was determined by qPCR. MC4exo treatment upregulated mRNA expression of Cd86, Il1β, Ccl2, Rankl and Nos, and downregulated Cd206, Il10 and Tnfα, suggesting a shift towards pro-inflammatory 'M1-like' macrophage polarization. Combination of RANKL and MC4exo increased osteoclast differentiation of BMMΦ in comparison to RANKL alone as analysed by TRAP staining. MC4exo treatment showed no significant effect on calvarial osteoblast mineralization. For in vivo studies, intratibial inoculation of MC4exo (2 × 10
