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

Human mesenchymal stem cells (MSC) hold great promise for cellular replacement therapies. Despite their contributing to phenotypically distinct cells in multiple tissues, controversy remains regarding whether the phenotype switch results from a true differentiation process. Here, we studied the events occurring during the first 120 h after human MSC transplantation into a large animal model. We demonstrate that MSC, shortly after engrafting different tissues, undergo proliferation and rapidly initiate the differentiative process, changing their phenotype into tissue-specific cells. Thus, the final level of tissue-specific cell contribution is not determined solely by the initial level of engraftment of the MSC within that organ, but rather by the proliferative capability of the ensuing tissue-specific cells into which the MSC rapidly differentiate. Furthermore, we show that true differentiation, and not cell fusion or transfer of mitochondria or membrane-derived vesicles between transplanted and resident cells, is the primary mechanism contributing to the change of phenotype of MSC upon transplantation.
