Laminin 332 regulates glial fibrillary acidic protein expression and astrocyte maturation during spinal cord development.

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
The white matter of the spinal cord is essential for sensory and motor signaling, and its proper development is crucial for establishing functional neuronal circuits. However, the mechanisms underlying white matter formation remain incompletely understood. We hypothesized that the extracellular matrix, particularly laminins, plays a key role in this process. The spatiotemporal expression patterns of laminins during spinal cord white matter development have not been fully characterized. Here, we examined the distribution and function of laminins during spinal cord development. Laminin 332 localized to the marginal zone of the spinal cord at embryonic days 12 (E12) and 14 (E14), coinciding with periods of extensive axonal growth. Immunohistochemical analysis revealed an increase in glial fibrillary acidic protein (GFAP)-positive fibers in laminin 332-enriched regions. Laminin 332 promoted GFAP expression in astrocyte precursor cells, an effect attenuated by integrin α6β4 blockade, suggesting that laminin 332 signals through integrins to support astrocyte maturation. Our findings indicate that laminin 332 not only serves as a structural component of the extracellular matrix but also actively regulates glial differentiation during spinal cord development. Understanding the signaling pathways mediated by laminin 332 may inform therapeutic strategies aimed at enhancing spinal cord regeneration by modulating astrocyte behavior and promoting axonal growth.
