Modeling Uterine Fibroids Using Bioengineered Hydrogels.

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
Uterine fibroids are the most common gynecological tumors, characterized by excessive production of extracellular matrix. Despite their prevalence, the cellular mechanisms governing fibroid growth remain poorly understood. Current in vitro models for fibroids do not replicate the complex 3D tissue mechanics, structure, and extracellular matrix components of fibroids, which may limit our understanding of fibroid pathogenesis. To address this gap, we aimed to develop a 3D in vitro model to mimic aspects of the fibroid microenvironment. By encapsulating human uterine fibroblasts in poly(ethylene glycol) (PEG)-based hydrogels comprising collagen- and fibronectin-derived peptides, this model allows for incorporation of fibroid cellular components, extracellular matrix components, and fibroid or myometrial tissue stiffness. Due to its mechanistic role in fibroblast activation and subsequent extracellular matrix production seen in fibroids, we treated uterine fibroblasts with transforming growth factor beta 3 (TGF-β3) to demonstrate quantification of fibrotic markers observed in fibroids. Here, we establish that human uterine fibroblasts increase α smooth muscle actin, extracellular matrix proteins, and cell elongation, as well as high metabolic activity and matrix remodeling in PEG-based hydrogels in response to TGF-β3. This research represents a physiologically relevant in vitro platform to investigate uterine fibroblast function within a 3D environment that mimics uterine fibroids, with the potential to advance our understanding of the cellular and molecular mechanisms driving fibroid growth and development.
