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

Cultured meat presents a sustainable alternative to traditional meat production but faces significant challenges in scalability and cost efficiency. A key limitation is the restricted proliferation capacity of bovine mesenchymal stem cells (bMSCs), a widely used cell source in the field. Using a pooled, lentiviral CRISPR knockout screen, we interrogated 3000 CRISPR guides targeting 600 genes involved in stem cell regulation or proliferation. Notably, knockouts of TP53 and PTEN significantly increased proliferation rates and delayed senescence. Validation with individual gene knockouts confirms these effects, showing enhanced growth but reduced differentiation potential. We also identified chondrogenic differentiation as a promising target whose repression may further promote MSC expansion. These findings demonstrate the utility of CRISPR screening for optimizing bovine stem cell traits and offer a path toward more scalable cultured meat production in the future.
