Establishment of a xenograft model of endometriosis-associated fibrosis using human immortalized endometrial stromal cells overexpressing HOXC8.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Endometriosis is a disease characterized by fibrosis and adhesions. There are still no treatment methods targeting these conditions. One reason for this is the lack of useful animal models to investigate the mechanisms of fibrosis and adhesion in endometriosis. We previously proposed that Homeobox C8 (HOXC8) acts as an upstream regulator involved in endometriosis development, promoting fibrosis by activating transforming growth factor β (TGFB) signaling in vitro. This study was undertaken to establish a xenograft mouse model for endometriosis-associated fibrosis using HOXC8-overexpressing cells. Stable lines of immortalized human endometrial stromal cells overexpressing HOXC8 (HOXC8-imESCs) and mock control lines (Control-imESCs) were established and evaluated for cellular functions in vitro. These cell lines were then transplanted under the renal capsule of severely immunodeficient mice, and the xenografts were harvested five weeks after transplantation. In vitro, cell migration, invasion, and fibrotic capacity were enhanced in HOXC8-imESCs compared to Control-imESCs. In the xenografts, HOXC8-imESCs exhibited significant collagen fiber production compared to Control-imESCs. Additionally, immunohistochemistry of the xenografts detected phosphorylated SMAD2/3 exclusively in HOXC8-imESCs, indicating that HOXC8 overexpression activates the TGFB/SMAD pathway aberrantly in vivo. In this study, a new animal model for endometriosis-associated fibrosis was established using the HOXC8-imESC xenograft model system.
