Comparative study of the dynamics of focal contacts in live epithelial and mesenchymal cells.
Article in Medical molecular morphology, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
To further characterize the morphology and dynamics of focal contacts (FCs) in epithelial cells, we compared the size, number, localization, velocity, and turnover of FCs in epithelial and mesenchymal cell lines. Using immunocytochemistry, we found there were no significant differences between mesenchymal and epithelial cells in number and appearance whereas the location and size of FCs in each cell were different between mesenchymal and epithelial cells. FCs in mesenchymal cells localized at the cell periphery and cell center, but FCs were found only at the cell periphery in epithelial cells. The size of FCs in epithelial cells were significantly smaller than in mesenchymal cells. Next, we compared the dynamics of FCs in both mesenchymal and epithelial cells and found no significant difference between the two groups. Finally, we added inhibitors for the hemidesmosome (HD) proteins, α6 integrin and β4 integrin, to HaCat cell (epithelial) cultures and examined the number and size of FCs. Under these conditions, the size and localization of FCs in HaCat cells became comparable to that of mesenchymal cells. Therefore, we concluded the size and localization of FCs is regulated by the existence of HDs in epithelial cells.
