A skeletal muscle atlas shows neuromuscular junction adaptations to growth and atrophy.
Article in Developmental cell, 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
The molecular basis underlying muscle atrophy, as it occurs during disuse or aging, and activity-induced hypertrophy remain poorly understood. A major challenge has been defining the diverse cellular and niche environments within skeletal muscle, which is mostly composed of multinucleated myofibers. Here, we present a single-nucleus and single-cell transcriptomic atlas, coupled with spatial profiling, of mouse limb skeletal muscle under resting conditions and during experimentally induced atrophy or hypertrophy. We identify condition-dependent shifts in muscle-resident cell populations and fiber-type-specific transcriptional responses. We also uncover extensive remodeling of the neuromuscular junction (NMJ), including the emergence of specialized synaptic myonuclei (SynM) and terminal Schwann cells (tSCs) associated with atrophic or hypertrophic states. High-resolution 3D imaging and spatial transcriptomics confirm these changes at the tissue level. Similar NMJ alterations are observed in denervated and exercised human muscle, supporting the translational relevance of this atlas for studying muscle plasticity and identifying therapeutic targets in muscle-related diseases.
