Heart cells with regenerative potential from pediatric patients with end stage heart failure: a translatable method to enrich and propagate.

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
Background. Human cardiac-derived progenitor cells (hCPCs) have shown promise in treating heart failure (HF) in adults. The purpose of this study was to describe derivation of hCPCs from pediatric patients with end-stage HF. Methods. At surgery, discarded right atrial tissues (hAA) were obtained from HF patients (n = 25; hAA-CHF). Minced tissues were suspended in complete (serum-containing) DMEM. Cells were selected for their tissue migration and expression of stem cell factor receptor (hc-kit). Characterization of hc-kit(positive) cells included immunohistochemical screening with a panel of monoclonal antibodies. Results. Cells, including phase-bright cells identified as hc-kit(positive), spontaneously emigrated from hAA-CHF in suspended explant cultures (SEC) after Day 7. When cocultured with tissue, emigrated hc-kit(positive) cells proliferated, first as loosely attached clones and later as multicellular clusters. At Day 21~5% of cells were hc-kit(positive). Between Days 14 and 28 hc-kit(positive) cells exhibited mesodermal commitment (GATA-4(positive) and NKX2.5(positive)); then after Day 28 cardiac lineages (flk-1(positive), smooth muscle actin(positive), troponin-I(positive), and myosin light chain(positive)). Conclusions. C-kit(positive) hCPCs can be derived from atrial tissue of pediatric patients with end-stage HF. SEC is a novel culture method for derivation of migratory hc-kit(positive) cells that favors clinical translation by reducing the need for exogenously added factors to expand hCPCs in vitro.
