Modulating iMSC Spheroid Function with Mechanically Tunable Hydrogels to Strengthen the Bone-Muscle Axis.
Article in ACS biomaterials science & engineering, 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
Bone fractures often involve both bone and muscle damage, representing a critical need for regenerative strategies that can repair both tissues. We developed a gelatin-based hydrogel system with tunable stiffness to guide spheroids formed from induced pluripotent stem cell (iPSC)-derived mesenchymal stromal cells (iMSCs) for simultaneous muscle and bone repair. Hydrogels were formed using hydrogen peroxide with horseradish peroxidase as a catalyst and substrate stiffness ranged from 1.6 to 9.3 kPa. Hydrogels entrapping iMSC spheroids enabled localized release of the iMSC secretome that exhibited biological effects. iMSC spheroids in soft hydrogels enhanced myogenic differentiation of C2C12 myoblasts via paracrine signaling. Conversely, iMSC spheroids exposed to the myoblast secretome and cultured in stiffer hydrogels exhibited enhanced osteogenic differentiation. This study demonstrates the synergistic influence of stiffness and reciprocal secretome signaling on iMSC behavior, offering a clinically relevant "two-in-one" platform for musculoskeletal regeneration.
