Local ADSC Delivery Methods Accelerate Healing of Large Unburned Full-Thickness Skin Defects by Promoting an Optimal Wound Microenvironment.
Article in Biomolecules, 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
backgroundThis study introduces an experimental model of a large, full-thickness skin defect and evaluates how adipose-derived stem cells characterized by high self-renewal and differentiation capacity affect both wound healing and the wound microenvironment when delivered using two different local application methods. MATERIALS AND
methodsIn this preclinical study, we established an excisional full-thickness skin defect model involving approximately 30% of the total body surface area (TBSA). Five experimental groups were formed, each containing equal numbers of male and female rats: (1) subdermal ADSC injection (ADSC-I) (n = 8), (2) application of an acellular dermal matrix (ADM) seeded with ADSCs (n = 8) (ADSC-ADM), (3) ADM alone (n = 8), (4) subdermal saline injection (n = 8) (SS-I), and (5) an untreated skin-defect sham group (n = 8). Wound healing and wound microenvironment parameters were assessed at regular intervals using macroscopic and microscopic evaluations, as well as various quantitative measurements. The study was terminated when complete wound closure was achieved in all animals of at least one experimental group.
resultsThe most favorable healing outcomes were observed in the two ADSC-treated groups. More favorable microenvironmental conditions in the stem cell groups were detected from day 14 onward. Complete closure of the dermal defects occurred by day 32 in the ADSC-I group, whereas none of the other groups achieved full wound closure within the study period.
conclusionsLocal application of adipose-derived stem cells may accelerate wound healing by favorably modulating the wound microenvironment.
