The hernia sac-A suitable source for obtaining mesenchymal stem cells.

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
backgroundInguinal hernia sac, extended tissue from peritoneum, gradually enlarged in size with hernia disease time and prolapsed tissue volume. We hypothesize that mesenchymal stem cells are present in the development of hernia sac. The current study aimed to test the hypothesis that hernia sac, which is often resected and discarded as medical waste, contains mesenchymal stem cells and thus might be a suitable source to harvest mesenchymal stem cells.
methodsBetween July 2019 and June 2020, 4 hernia sacs were resected during hernia surgery and then obtained for mesenchymal extraction using the Miltenyi gentleMACS Dissociator. The presence of mesenchymal stem cells was determined by the markers CD105, CD73, and CD90, with assessment of the expressions ≥ 95%, whereas markers CD45, CD34, CD11b, CD19, and HLA-DR were used to assess lack expression (≤ 2%). Moreover, von Kossa staining, Alcian blue staining, and Oil Red O staining were used to verify the cells' ability for differentiation.
resultsCells retrieved from the hernia sacs displayed a spindle-shaped morphology and exhibited adherence to plastics. The cell surface immunophenotypic profile was confirmed using surface markers APC-A (CD73), FITC-A (CD90), and PerCP-Cy5-5-A (CD105), with results showing 100%, 100%, and 99.2%, respectively, strongly indicating the presence of mesenchymal stem cells. Moreover, staining of in vitro cell cultures showed in vitro differentiation of precursor cells into osteoblasts, adipocytes, and chondroblasts, suggesting positive differentiation ability and identification of mesenchymal stem cells.
conclusionInguinal hernia sac is a novel source of mesenchymal stem cells that can be easily obtained and stored for future usage.
