Single-cell transcriptomic analyses reveal angiogenic vascular responses to chronic cerebral hypoperfusion.
Article in iScience, 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
Elucidating the mechanisms underlying vascular injury and repair may guide development of therapies against vascular cognitive impairment and dementia (VD). We employed single-cell RNA sequencing to map cell populations and explore vascular responses in mouse brains collected 42 days after asymmetric common carotid artery stenosis (ACAS)-induced chronic cerebral hypoperfusion. A unique tip cell type was identified among endothelial cell (EC) clusters and validated by immunostaining. Gene Ontology analyses suggested tip cell enrichment in angiogenesis and the involvement of Apln/Aplnr signaling. Immunoblotting confirmed an increase in apelin (Apln) protein after ACAS. In EC cultures, [Pyr1]-Apelin-13 (Apln13), a selective endogenous apelin receptor agonist, enhanced EC proliferation, migration, and tube formation. Treatment with Apln13 also improved angiogenesis, white matter integrity, and cognitive functions in ACAS mice. Cell-cell interaction analyses highlighted astrocyte-tip cell crosstalk via Vegfa-Vegfr interactions.
