Neural Crest-Derived Mesenchymal Cells Support Thymic Reconstitution After Lethal Irradiation.
Article in European journal of immunology, 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
Reconstitution of the thymus is essential for assessing thymic function following injury. However, the currently employed cytoreductive regimes unvaryingly affect the thymic microenvironment, thereby impeding the recovery of T lymphopoiesis. The thymic stroma is composed of epithelial and mesenchymal cells. Thymic mesenchymal cells originate from the Neural crest (NC) and mesoderm and contribute to thymus organogenesis, yet their role in thymic regeneration is unclear. In this study, using transgenic mice expressing NC-specific Cre and Cre-driven DT receptors, we investigated the role of NC-derived mesenchymal cells in thymic regeneration following total body irradiation. We revealed that NC-derived mesenchymal cells have reduced susceptibility to irradiation and induce the upregulation of hematopoietic factors that promote thymus regeneration after irradiation. Additionally, using adult thymic organ culture and renal capsule transplantation, depletion of NC-derived mesenchymal cells resulted in a reduction of DN1-like early T-cell progenitors (ETP) and impaired thymic regeneration. Furthermore, among the numerous factors upregulated by NC-derived mesenchymal cells, Periostin and Flt3L were markedly increased after irradiation and promoted abundance of DN1-like ETPs during thymic reconstitution. Collectively, these findings highlight the importance of NC-derived mesenchymal cells in thymic regeneration.
