Cardiogenic Regulation of Stem-Cell Electrical Properties in a Laser-Patterned Biochip.
Article in Cellular and molecular bioengineering, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
Normal cardiomyocytes are highly dependent on the functional expression of ion channels to form action potentials and electrical coupling with other cells. To fully determine the scientific and therapeutic potential of stem cells for cardiovascular-disease treatment, it is necessary to assess comprehensively the regulation of stem-cell electrical properties during stem cell-cardiomyocyte interaction. It has been reported in the literature that contact with native cardiomyocytes induced and regulated stem-cell cardiogenic differentiation. However, in conventional cell-culture models, the importance of cell-cell contact for stem-cell functional coupling with cardiomyocytes has not been elucidated due to insufficient control of the cell-contact mode of individual cells. Using microfabrication and laser-guided cell micropatterning techniques, we created two biochips with contact-promotive and -preventive microenvironments to systematically study the effect of contact on cardiogenic regulation of stem-cell electrical properties. In contact-promotive biochips, connexin 43 expression was upregulated and relocated to the junction area between one stem cell and one cardiomyocyte. Only stem cells in contact with cardiomyocytes were induced by adjacent cardiomyocytes to acquire electrophysiological properties for action-potential formation similar to that of a cardiomyocyte.
