Application of a reversible immortalization system for the generation of proliferation-controlled cell lines.
Article in Cytotechnology, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 employ physiological mechanisms to control cell growth primary cells were reversibly immortalized using the SV40 TAg. The cells showed a fibroblast-like morphology. When the expression of the TAg was turned off, the cells arrested in the G0/G1 cell cycle phase. The cell culture could be kept for over 1 week in the proliferation-controlled state while the growth arrest remained fully reversible. The regulation was highly efficacious in that the arrested cell population did not spontaneously resume growth, suggesting that in the absence of the immortalizing gene expression endogenous growth-control mechanisms can keep these cells in a viable state for a prolonged time. Recombinant protein expression increased in growth-controlled cells when compared to conventionally cultured cells. Analysis of a secreted pharmaceutical protein revealed high product integrity without any signs of degradation. Therefore, it is feasible to apply genetic regulation of cell immortalization to obtain proliferation-controlled cell lines and this technique may be of interest to generate novel biotechnological producer cells.
