Tissue Dissociation Workflows Influence Reactive Astrocyte Recovery in Single-Cell Transcriptomics.
Article in Molecular neurobiology, 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
Single-cell RNA sequencing has advanced our understanding of glial diversity, yet tissue dissociation remains an important technical variable. We revealed that a widely used commercial dissociation protocol can underrepresent reactive astrocytes in an acute ischemic stroke model, with preliminary observations indicating a comparable trend in a chronic tauopathy model. Benchmarking against an optimized, low-shear workflow demonstrates that different tissue dissociation workflows can substantially alter the recovery and apparent transcriptomic profile of disease-associated astrocytes, selectively losing signatures of morphological remodeling. Our findings indicate that workflow-dependent recovery biases affecting reactive astrocytes may be more prevalent than recognized, underscoring the need for pathology-tailored, gentle isolation workflows to avoid distortions in downstream neuropathological interpretations and the prioritization of therapeutic targets.
