Thymopoiesis in mice depends on a Foxn1-positive thymic epithelial cell lineage.
Article in Proceedings of the National Academy of Sciences of the United States of America, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 70 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
The thymus is essential for T-cell development. Here, we focus on the role of the transcription factor Foxn1 in the development and function of thymic epithelial cells (TECs) of the mouse. TECs are of endodermal origin; they initially express Foxn1 and give rise to orthotopic (thoracic) and additional (cervical) thymi. Using Foxn1-directed cytoablation, we show that during embryogenesis, cervical thymi develop a few days after the thoracic lobes, and that bipotent epithelial progenitors of cortical and medullary compartments express Foxn1. We also show that following acute selective near-total ablation during embryogenesis, complete regeneration of TECs does not occur, providing an animal model for human thymic aplasia syndromes. Finally, we address the functional role of Foxn1-negative TECs that arise postnatally in the mouse. Lineage tracing shows that such Foxn1-negative TECs are descendants of Foxn1-positive progenitors; furthermore, Foxn1-directed subacute intoxication of TECs by polyglutamine-containing EGFP proteins indicates that a presumptive Foxn1-independent lineage does not contribute to thymopoietic function of the adult thymus. Our findings therefore support the notion that Foxn1 is the essential transcription factor regulating the differentiation of TECs and that its expression marks the major functional lineage of TECs in embryonic and adult thymic tissue.
