The Influence of Cisplatin on Functionality and Surface Characteristics of Mesenchymal Stromal Cells In Vitro.

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
Mesenchymal stromal cells (MSCs) are multipotent and play an important role in regenerative processes such as wound healing. Data on possible changes and functional restrictions of MSCs due to cisplatin chemotherapy, for example, in the treatment of head and neck cancer, diverge. The aim of this study was to evaluate the influence of cisplatin on MSCs with regard to their defining characteristics and their ability to differentiate and to migrate. MSCs from four human donors (a 59-year-old man, a 63-year-old woman, a 70-year-old man, and a 61-year-old man) were cultured in vitro with and without cisplatin for 24 h, and toxic and subcytotoxic concentrations were determined using an MTT. We then examined the surface phenotype markers (flow cytometry), migration (scratch assay), histological differentiation markers (adipo-, chondro-, osteogenic), and the expression of selected line-associated genes in real-time quantitative PCR (RT-qPCR) (LEP, SOX9, RUNX2). These characteristics were evaluated after treatment with different subcytotoxic, clinically relevant doses of cisplatin. Flow cytometry confirmed the presence of MSCs-characteristic surface markers, which remained stable under treatment with subcytotoxic doses of cisplatin. Cisplatin exposure reduced the mRNA abundance of leptin (a marker for adipogenic differentiation) but increased SOX9 mRNA abundance (chondrogenic differentiation). RUNX (osteogenic differentiation) did not change post cisplatin exposure. Histological analysis showed no difference with regard to osteogenic, chondrogenic, and adipogenic differentiation at doses up to 10 μM cisplatin. Cell migration was not restricted by cisplatin exposure under the conditions used here. The characteristics of MSCs were not different to controls post cisplatin exposure. mRNA analysis suggested induced changes by cisplatin, although this effect was not histologically detectable even at high doses. Based on the single-molecule markers used here, indications for an inhibitory effect of cisplatin on adipogenic differentiation and a rather enhancing effect on chondrogenic and osteogenic differentiation may be hypothesized. The process observed here could further aggravate the already serious problem of malnutrition in head and neck cancer patients, for example. Taken together though, our study confirms overall MSCs tolerance towards cisplatin.
