Pre-Vascularized 3-Dimensional Skin Substitutes Promote Angiogenesis and Tissue Repair in a Murine Model of Refractory Skin Ulcers.
Article in Journal of functional biomaterials, 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
Restoring blood flow is crucial for treating refractory ulcers. Despite advancements in various biomaterials, none incorporating pre-formed blood vessels have been commercialized. To address this, we developed a pre-vascularized three-dimensional (3D) skin substitute (PV-3D skin) designed to enhance healing when treating refractory ulcers. This study aimed to evaluate the therapeutic role of PV-3D skin transplantation in refractory ulcer models, induced by applying mitomycin C to wounds in severe immunodeficient mice. The wounds were then treated with PV-3D skin, non-vascularized 3D skin, skin grafts, or wound dressings. The PV-3D skin group demonstrated healing dynamics comparable to those of the skin graft group, with similar tissue morphology and wound temperature changes. Furthermore, at day 7 post-transplantation, the PV-3D skin group demonstrated significantly higher hypoxia-inducible factor 1-alpha expression levels compared to the 3D skin group. By day 14, the PV-3D skin group exhibited a significantly larger vascular area compared to the 3D skin group. Notably, PV-3D skin treatment stimulated host-derived angiogenesis, thereby enhancing wound healing and reducing the recurrence of refractory ulcers. These results suggest that PV-3D skin transplantation offers a promising therapeutic approach for refractory ulcers, especially in terms of angiogenesis.
