Improved Healing of Colonic Anastomosis with Allotransplantation of Axillary Skin Fibroblasts in Rats.
Article in Cell journal, 2022. 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
Objective: Colonic anastomosis is associated with serious complications leading to significant morbidity and mortality. Fibroblasts have recently been introduced as a practical alternative to stem cells because of their differentiation capacity, anti-inflammatory, and regenerative properties. The aim of this study was to evaluate the effects of intramural injection of fibroblasts on the healing of colonic anastomosis in rats. Materials and Methods: Inbred mature male Wistar rats were used in this experimental study (n=36). Fibroblasts were isolated from the axillary skin of a donor rat. In the sham group, manipulation on descending colon was done during laparotomy. A 5 mm segment of the colon was resected, and end-to-end anastomosis was performed. In the control group, 0.5 ml of phosphate buffer saline (PBS) was injected into the colonic wall and in the treatment group, 1×10 Results: The mean scores for adhesion and leakage were decreased in the treatment group versus control samples. Lower infiltration of inflammatory cells was observed in the treatment group (P=0.03). Angiogenesis and collagen deposition scores were significantly increased in the fibroblast transplanted group (P=0.03). Tensile mechanical properties of the colon were significantly increased in the treatment group compared to the control sample (P=0.01). There was no significant difference between the control and treatment groups in terms of bursting pressure (P=0.10). Positive weight changes were found in sham and treatment groups, but the control rats lost weight after 7 days. Conclusion: The results suggested that allotransplantation of dermal fibroblasts could improve the necroscopic, histopathological, and biomechanical indices of colonic anastomosis repair in rats.
