Development and characterization of in vitro inducible immortalization of a murine microglia cell line for high throughput studies.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
There are few in vitro models available to study microglial physiology in a homeostatic context. Recent approaches include the human induced pluripotent stem cell model, but these can be challenging for large-scale assays and may lead to batch variability. To advance our understanding of microglial biology while enabling scalability for high-throughput assays, we developed an inducible immortalized murine microglial cell line using a tetracycline expression system. The addition of doxycycline facilitates rapid cell proliferation, allowing for population expansion. Upon withdrawal of doxycycline, this monoclonal microglial cell line differentiates, resembling in vivo microglial physiology as demonstrated by the expression of microglial genes, innate immune responses, chemotaxis, and phagocytic abilities. We utilized live imaging and various molecular techniques to functionally characterize the clonal 2E11murine microglial cell line. Transcriptomic analysis showed that the 2E11 line exhibited characteristics of immature, proliferative microglia during doxycycline induction, and further differentiation led to a more homeostatic phenotype. Treatment with transforming growth factor-β modified the transcriptome of the 2E11 cell line, affecting cellular immune pathways. Our findings indicate that the 2E11 inducible immortalized cell line is a practical and convenient tool for studying microglial biology in vitro.
