1 · What the graph read from it

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.

2 · The registry

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

In this study, we present a straightforward approach for functional cell-based screening by co-encapsulation of secretor yeast cells and reporter mammalian cells in millions of individual agarose-containing microdroplets. Our system is compatible with ultra-high-throughput selection utilizing standard fluorescence-activated cell sorters (FACS) without need of extensive adaptation and optimization. In a model study we co-encapsulated murine interleukin 3 (mIL-3)-secreting S. cerevisiae cells with murine Ba/F3 reporter cells, which express green fluorescent protein (GFP) upon stimulation with mIL-3, and could observe specific and robust induction of fluorescence signal compared to a control with yeast cells secreting a non-functional mIL-3 mutant. We demonstrate the successful enrichment of activating mIL-3 wt-secreting yeast cells from a 1:10,000 dilution in cells expressing the inactive cytokine variant by two consecutive cycles of co-encapsulation and FACS. This indicates the suitability of the presented strategy for functional screening of high-diversity yeast-based libraries and demonstrates its potential for the efficient isolation of clones secreting bioactive recombinant proteins.
