Methods and Technical Issues for Optimizing the Production of Hydrogels Containing Decellularized Wharton's Jelly.
Article in ACS biomaterials science & engineering, 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
Bioinspired scaffolds, designed to mimic natural tissue and provide biological cues for tissue regeneration, are becoming increasingly important in the field of tissue engineering. We previously developed hydrogel scaffolds based on alginate and decellularized Wharton's jelly (DWJ) from an umbilical cord. These scaffolds have proven to be highly effective in promoting the recovery of the lost discogenic phenotype in degenerated intervertebral disc (IVD) cells obtained from patients undergoing discectomy. This prompted us to refine the various steps of the protocol to optimize the development of stable DWJ-based scaffolds with anatomically shaped geometries such as millimeter-scale cylinders (millicylinders) suitable for use in articular cartilage tissue engineering. Particular attention was paid to the handling of the materials used, the reproducibility of data, and the adaptability of the developed system to different experimental needs/conditions, including the transmission of mechanical stimuli and the evaluation of the reactivity of the combined cells. Here, we report the characterization of both the physicochemical properties of the hydrogel produced and its specific biological effects by using IVD cells and macrophages as experimental models. The detailed description of the various steps provides a protocol that aims to facilitate the development of DWJ-based hydrogels that may provide new strategies for addressing joint degeneration.
