Nanofiber-based platform for quantitative analysis of human oligodendrocyte ensheathment with pharmacological perturbations.
Article in Stem cell reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Oligodendrocytes are glial cells responsible for myelination in the central nervous system, and their dysfunction underlies various neurological disorders. However, existing human oligodendrocyte models are limited by low efficiency and insufficient standardization. Here, we developed a well-defined system for differentiating human oligodendrocytes from induced pluripotent stem cells using transient transcription factor expression. To recapitulate key structural aspects of oligodendrocyte-axon interactions, we cultured oligodendrocytes on nanofibers mimicking axonal topology. On this platform, ultrastructural, live-imaging, and transcriptomic analyses demonstrated dynamic oligodendrocyte-nanofiber interactions and ensheathment-like wrapping. This process was accompanied by aligned CLDN11 expression along nanofibers, providing a quantifiable structural readout without overt maturation. To validate the utility of the platform, we quantified the effects of white matter toxins and pro-ensheathment lipids. Our findings establish a robust system for evaluating oligodendrocyte ensheathment modulators, particularly those affecting cytoskeletal organization and initial sheath formation, and for investigating the pathophysiology of human oligodendrocyte-related disorders.
