iPSC-modelling reveals genetic associations and morphological alterations of oligodendrocytes in schizophrenia.

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
There is strong evidence for a genetically driven neuronal contribution in schizophrenia (SCZ). Although imaging and postmortem studies also provide evidence for white matter alterations with implications of the oligodendroglial lineage in SCZ, it is unclear whether these disturbances are a secondary consequence of neuronal deficits or also, at least in parts, genetically driven and cell-autonomous. Using human induced pluripotent stem cells (hiPSCs) in combination with gene set enrichment analysis, we investigated the cellular impact of SCZ genetics on the oligodendroglial lineage. We performed unsupervised clustering analysis of hiPSC-differentiated neural cells including oligodendrocytes (iOLs) and their precursor cells (iOPCs) with corresponding human postmortem cell types from single-cell RNA sequencing (scRNAseq) data and conducted a comparative gene set enrichment analysis. Subsequently, we stratified individuals based on white matter alteration using diffusion tensor imaging (DTI) within a translational cohort (N = 112) and then explored the cellular effects of SCZ risk with hiPSC modelling in a subset of SCZ patients (N = 8) with disturbed white matter integrity and unaffected healthy controls (N = 7). hiPSC-iOPCs/iOLs expression profiles strongly correlated with human postmortem OPCs/OLs based on scRNAseq, and their transcriptional signatures were highly enriched in the genetic associations of SCZ. The cellular assessment of patient-derived iOPCs/iOLs revealed morphological alterations, including significantly increased branch length and elevated junction number in mature iOLs from SCZ. Moreover, transcriptomic profiling revealed a dysregulation in oligodendroglial cell signaling and proliferation. In sum, hiPSC-modelling shows an impact of SCZ genetics on dedicated features of the oligodendroglial lineage.
