Prion Protein and Stage Specific Embryo Antigen 1 as Selection Markers to Enrich the Fraction of Murine Embryonic Stem Cell-Derived Cardiomyocytes.
Article in Yonago acta medica, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe prion protein (PrP) might be useful as a tool to collect cardiac progenitor cells derived from embryonic stem (ES) cells. It is also possible that PrP(+) cells include undifferentiated cells with a capacity to develop into tumors.
methodsPrP(+) cells isolated from embryoid bodies (EB) formed by mouse AB1 ES cells were examined using RT-PCR analysis and clonogeneic cell assay. To assess their potential to differentiate into cardiomyocytes, Nkx2.5(GFP/+) (hcgp7) cells, another ES cell line that carries the GFP reporter gene in the Nkx2.5 loci, were used.
resultsPrP(+) cells isolated from EB of day 7 and 14 did not express pluripotency markers, but expressed cardiac cell markers, while PrP(+) cells isolated from EB of day 21 expressed pluripotency markers. Cultured PrP(+) cells isolated from EB of day 21 expressed pluripotency markers to form colonies, whereas those isolated from EB of day 7 and 14 did not. To exclude proliferating cells from PrP(+) cells, stage specific embryo antigen 1 (SSEA1) was employed as a second marker. PrP(+)/SSEA1(-) cells did not proliferate and expressed cardiac cell markers, while PrP(+)/SSEA1(+) did proliferate.
conclusionPrP(+) cells isolated from EB included undifferentiated cells in day 21. PrP(+)/SSEA1(-) cells included cardiomyoctes, suggesting PrP and SSEA1 may be useful as markers to enrich the fraction of cardiomyocytes.
