Hierarchical Porous Egg White Hydrogel Promotes Diabetic Wound Closure through Topography-Guided Cell Recruitment.
Article in Biomaterials research, 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
Skin healing often results in scarring or pathological conditions like keloids due to abnormal cell proliferation. These outcomes are attributed to abnormal proliferation or functional defects in skin cells. Hydrogels, mimicking the extracellular matrix, can guide hierarchical cell alignment for improved regeneration. Inspired by egg white's foaming ability, we engineered a bilayer hydrogel dressing: a porous dermis layer via whipped egg white and a dense epidermis layer crosslinked with calcium. The artificial egg white skin (EWS) was tested in in vitro cell culture and in vivo application on mouse wounds. RNA sequencing explored the specific mechanism of EWS on cells. EWS features a multistage macroporous structure mimicking skin's longitudinal mechanical performance. This migration inducive property of egg white facilitates directional migration and allows for the vertical stacking of keratinocytes and fibroblasts. The collaboration of cells enhances expression of positive chemokines and growth factors, shortening inflammation reaction and improving wound healing. Transcriptome sequencing reveals a substantial up-regulation of genes related to cell cycle and metabolism. EWS offers a cost-effective and efficient platform for biomimetic skin dressing and shows potential for other applications in regenerative medicine.
