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

backgroundExtracellular vesicle (EV)-based cell-free therapies have emerged as a powerful alternative to stem cell transplantation in regenerative medicine, owing to their ability to promote tissue repair while avoiding safety concerns associated with live-cell therapies. However, traditional two-dimensional (2D) cell cultures used for EV production are constrained by low exosome (Exo) yields and limited biological activity.

objectiveThis study introduces a novel and scalable three-dimensional (3D) culture platform based on a hyaluronic acid (HA) and L-ornithine methyl ester (Orn) hydrogel to enhance the production and therapeutic efficacy of stem cell-derived exosomes.

methodsThe HA-Orn hydrogel was fabricated via a simple and mild crosslinking strategy, forming a biomimetic matrix that promotes spontaneous spheroid formation. Exosomes derived from 3D cultures (3D-Exo) were compared with those from 2D cultures (2D-Exo) in terms of yield, molecular composition, and biological functions.

results3D-Exo exhibited significantly increased yield and superior functional properties, including enhanced stimulation of cell proliferation, migration, angiogenesis, and extracellular matrix remodeling. In vivo, 3D-Exo treatment accelerated wound closure and reduced inflammation in a mouse skin injury model, demonstrating robust therapeutic efficacy and safety. Mechanistic studies revealed distinct miRNA expression profiles and activation of regenerative signaling pathways in 3D-Exo.

conclusionThis work presents a cost-effective, scalable, and bioinspired 3D culture system for high-yield and functionally enhanced Exo production. The HA-Orn hydrogel platform offers significant translational potential for advancing cell-free regenerative therapies, particularly in the context of wound healing.
