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

Female germline stem cells (FGSCs) have been found in mouse, rat, pig, sheep and human ovaries. However, there is no information on the isolation or long-term culture of FGSCs from non-human primates. Here, we identified the presence of FGSCs in the ovaries of juvenile (3-4-year-old) cynomolgus monkeys using DDX4 and Ki67 double immunofluorescence. Then, a long-term serum- and cell feeder-free culture system for these FGSCs was used to establish a cell line, and its biological characteristics were analyzed. We found that testosterone promoted self-renewal of the cells. This study confirmed for the first time the presence of FGSCs in the ovary of non-human primates. This culture system and cell line will be of great significance for research in medicine and reproductive biology.
