1 · What the graph read from it

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.

2 · The registry

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

objectiveThis study aimed to evaluate the potential of a collagen-coated, 3D-printed tracheal scaffold (3D-TechTra) integrated with human umbilical cord mesenchymal stem cells (hUC-MSCs) for tracheal tissue regeneration.

methodsThe thermoplastic polyurethane/polylactic acid (TPU/PLA) scaffold was engineered to optimize mechanical properties and biocompatibility, with the goal of mimicking the structural and tensile characteristics of native tracheal tissue. Subsequently, preclinical experiments were conducted using rabbit models: the performance of the collagen-coated TPU/PLA scaffold with hUC-MSCs was compared with that of uncoated scaffolds and collagen-only scaffolds. In vitro tests were also performed to assess the adhesion, proliferation, and differentiation of hUC-MSCs on the scaffold. For in vivo evaluation, multiple analytical methods were employed, including immunohistological analysis (to detect glycosaminoglycan deposition and extracellular matrix remodeling), radiographic and endoscopic evaluations (to assess tracheal contour and airway obstruction), and survival analysis (to monitor animal outcomes and systemic toxicity).

resultsIn vitro, hUC-MSCs successfully adhered to and proliferated on the TPU/PLA scaffold, and differentiated into adipogenic, osteogenic, and chondrogenic lineages, which supported the potential for tissue-specific regeneration; in vivo, compared with uncoated or collagen-only scaffolds, the collagen-coated TPU/PLA scaffold integrated with hUC-MSCs exhibited enhanced integration with host tissues, superior biocompatibility, and reduced tracheal stenosis, while also preserving airway patency, alleviating inflammation, and facilitating epithelial regeneration, smooth muscle formation, and vascularization. Immunohistological analysis further revealed significant glycosaminoglycan deposition and extracellular matrix remodeling in the hUC-MSC-treated group, and radiographic and endoscopic evaluations confirmed preserved tracheal contour and reduced airway obstruction; additionally, survival analysis showed significantly improved outcomes in animals treated with the collagen-coated TPU/PLA scaffold containing hUC-MSCs, with no systemic toxicity observed.

conclusionsThis study demonstrated the synergistic potential of TPU/PLA scaffolds, collagen coatings, and hUC-MSCs, providing valuable evidence for advancing the application of these components in tracheal tissue engineering.
