1 · What the graph read from it

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.

2 · The registry

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

Therapeutic applications of tissue-derived mesenchymal stem cells (MSCs) are hindered by their limited expansion ability and variation across donors. Human induced pluripotent stem cell (iPSC)-derived MSCs show greater expandability and therefore offer potential for use in tissue repair therapies. Here we explored the regenerative effects of iPSC-MSCs and the mechanisms by which iPSC-MSCs promote mucosal healing via tumor necrosis factor-α-stimulated gene 6 (TSG-6) in mouse models of inflammatory bowel disease (IBD). Human iPSCs were induced to differentiate into MSCs following a clinically compliant protocol. The iPSC-MSC treatment promoted mucosal healing in colitic mice, accompanied by increased epithelial cell proliferation, CD44-positive cells, and Lgr5-positive cells. TSG-6 knockdown in iPSC-MSCs or blocking of hyaluronan-CD44 interactions by PEP-1 abrogated the therapeutic effects of iPSC-MSCs, whereas use of recombinant TSG-6 showed therapeutic effects similar to those of iPSC-MSCs. A mouse or patient-derived organoid culture system was developed. Organoids co-cultured with iPSC-MSCs showed increased epithelial cell proliferation, CD44-positive cells, and Lgr5-positive cells, which was abolished by TSG-6 knockdown. TSG-6-induced promoting effects in organoids were dependent on Akt activation and abrogated by the anti-CD44 antibody or MK2206. In conclusion, iPSC-MSCs promoted epithelial cell proliferation to accelerate mucosal healing in a murine colitis model via TSG-6 through hyaluronan-CD44 interactions in an Akt-dependent manner, demonstrating a patient-specific "off-the-shelf" format for IBD treatment.
