Cortical Spheroid Model for Studying the Effects of Ischemic Brain Injury.
Article in In vitro models, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
Purpose: Ischemic brain injury occurs when there is reduced or complete disruption of blood flow to a brain region, such as in stroke or severe traumatic brain injury. Even short interruptions can lead to devastating effects including excitotoxicity and widespread cell death. Despite many decades of research, there are still very few therapeutic options for patients suffering from brain ischemia. Methods: We developed an in vitro brain ischemia model using our previously established 3D spheroids derived from primary postnatal rat cortex. These spheroids provide an in vivo-relevant model containing a similar cellular composition to the native cortex and a cell-synthesized extracellular matrix. This model is cost-effective, highly reproducible, and can be produced in a high-throughput manner, making it an ideal candidate for screening potential therapeutics. To study the cellular and molecular mechanisms of stroke in this model, spheroids were deprived of glucose, oxygen, or both oxygen and glucose for 24 h. Results: Both oxygen and oxygen-glucose deprived spheroids demonstrated many of the hallmarks of ischemic brain injury, including a decrease in metabolism, an increase in neural dysfunction, breakdown in the neurovascular unit, and an increase in reactive astrocytes. Pretreatment of spheroids with the antioxidant agent N-acetylcysteine (NAC) mitigated the decrease in ATP after oxygen-glucose deprivation, was partially neuroprotective, and enhanced the expression of laminin. Conclusion: This 3D cortical spheroid model provides a platform for studying ischemic injury and has the potential for screening therapeutics.
