Expansion of human embryonic stem cells: a comparative study.
Article in Cell proliferation, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectivesHuman embryonic stem cells (hESC) are promising for tissue engineering (TE) purposes due to their unique properties. However, current standard mechanical passaging techniques limit rates of possible TE experiments, as it is difficult to obtain high enough numbers of the cells for experimentation. In this study, several dissociative solutions and application methods are tested for their applicability to, and influence on, hESC culture and expansion. MATERIALS AND
methodsExpansion of two hESC lines, H1 and VUB01, subjected to different passaging techniques, was evaluated. Four dissociative solutions - TrypLE™ Express, Trypsin-EDTA, Cell Dissociation Solution and Accutase™- were combined with two application protocols. As reference conditions, manual and bead-based passaging techniques were used.
resultsResults showed that use of Cell Dissociation Solution in combination with a slow adaptation protocol, generated the best expansion profile for both cell lines. The hESC single cell lines remained pluripotent, had good expansion profiles and were capable of differentiation into representatives of all three germ layers. Reproducibility of the results was confirmed by adaptation for three other hESC lines.
conclusionUse of Cell Dissociation Solution, combined with slow adaptation protocol, allows a fast switch from the mechanical passaging technique to a single-cell split technique, generating stable and robust hESC cell lines, which allow for large scale expansion of hESC for TE purposes.
