Brain pericytes derived from human pluripotent stem cells retain vascular and phagocytic functions under hypoxia.
Article in Stem cells (Dayton, Ohio), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe integrity and function of the blood‑brain barrier (BBB) are largely regulated by pericytes. Pericyte deficiency leads to BBB breakdown and neurological dysfunction in major neurological disorders including stroke and Alzheimer's disease (AD). Transplantation of pericytes derived from induced pluripotent stem cells (iPSC‑PC) has been shown to restore the BBB and improve functional recovery in mouse models of stroke and pericyte deficiency. However, the molecular profile and functional properties of iPSC‑PC under hypoxic conditions, similar to those found in ischemic and neurodegenerative diseases remain largely unexplored.
methodsWe examined iPSC‑PC under hypoxia to assess molecular marker expression, proliferation, ability to home to brain vessels, and uptake of amyloid beta (Aβ).
resultsiPSC‑PC under severe hypoxia retain essential functional properties, including key molecular markers, proliferation rates, and the ability to migrate to host brain vessels via function‑associated PDGFRB‑PDGF‑BB signaling. Additionally, we show that iPSC‑PC exhibit similar clearance of Aβ neurotoxins from AD mouse brain sections under both normoxic and hypoxic conditions.
conclusionsThese findings suggest that iPSC‑PC functions are largely resilient to hypoxia, highlighting their potential as a promising cell source for treating ischemic and neurodegenerative disorders.
