Navigating Human Astrocyte Differentiation: Direct and Rapid One-Step Differentiation of Induced Pluripotent Stem Cells to Functional Astrocytes Supporting Neuronal Network Development.
Article in Glia, 2026. 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
Astrocytes play a pivotal role in neuronal network development. Despite the well-known role of astrocytes in the pathophysiology of neurologic disorders, the utilization of induced pluripotent stem cell (iPSC)-derived astrocytes in neuronal networks remains limited. Here, we present a streamlined one-step protocol for the differentiation of iPSCs directly into functional astrocytes without the need for ectopic gene expression or neural progenitor cell generation. We found that culturing iPSCs directly in commercial astrocyte medium, was sufficient to differentiate iPSCs into functional astrocytes within 5 weeks. More than 60 iPSC lines were successfully differentiated into astrocytes by independent researchers across 10 independent laboratories. Validation of the iPSC-astrocyte cultures demonstrated consistent astrocyte differentiation with minimal batch-to-batch variability. In dept. characterization of a subset of iPSC lines confirmed astrocyte identity and functionality of the iPSC-astrocyte monocultures by immunofluorescence, flow cytometry, RNA sequencing, glutamate uptake assays and calcium signaling recordings. Optimization of the protocol enabled co-culture of iPSC-astrocytes with Ngn2 iPSC-derived neurons (iNeurons), promoting neuronal differentiation and synapse formation. Lastly, we used single-cell electrophysiology and multi-electrode arrays, by four independent researchers, to confirm robust neuronal network development in 5-week-old iPSC-astrocyte and iNeuron co-cultures. This protocol offers a rapid and efficient method to establish all-human astrocyte-neuron co-cultures, facilitating the investigation of cell-type-specific contributions to disease pathogenesis. Its validation across numerous iPSC lines in 10 independent laboratories highlights the reproducibility of the protocol and positions it as a platform for advancing disease modeling in human neural networks.
