Macrophage and fibro-adipogenic progenitor communication in skeletal muscle regeneration: tissue homeostasis and pathogenic remodeling.
Review in Journal of leukocyte biology, 2026. 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
Skeletal muscle regeneration depends on coordinated interactions between macrophages, fibro-adipogenic progenitors, and muscle stem cells. Following injury, macrophages transition from proinflammatory to anti-inflammatory phenotypes, regulating debris clearance, cytokine secretion, and the activity of fibro-adipogenic progenitors and muscle stem cells. Fibro-adipogenic progenitors transiently support muscle stem cell-mediated regeneration but, if not cleared appropriately, differentiate into fibroblasts or adipocytes, contributing to fibrosis and fatty infiltration. Dysregulated macrophage-fibro-adipogenic progenitor crosstalk drives pathological conditions, including Duchenne muscular dystrophy and age-related sarcopenia, where imbalances in cytokines and growth factors exacerbate maladaptive remodeling. Fibro-adipogenic progenitor-derived colony-stimulating factor 1 sustains macrophage survival while macrophage-derived signals, including tumor necrosis factor alpha and transforming growth factor beta, regulate fibro-adipogenic progenitor apoptosis, proliferation, and differentiation, shaping the regenerative niche. Single-cell and spatial transcriptomic approaches have revealed extensive heterogeneity among resident and infiltrating macrophages and fibro-adipogenic progenitor subsets, uncovering the molecular circuits underlying intercellular communication. Therapeutic strategies targeting cytokines and growth factors show promise in restoring balanced macrophage-fibro-adipogenic progenitor signaling, enhancing regeneration, and limiting fibrosis and fatty infiltration. Understanding the temporal dynamics of macrophage-fibro-adipogenic progenitor interactions is essential for developing interventions that preserve muscle homeostasis and counteract degenerative disease.
