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

objectivesIn vitro differentiation of oocytes from female germline stem cells (FGSCs) has exciting potential applications for reproductive medicine. Some researchers have attempted to reveal the in vitro differentiation capacity of FGSCs. However, no systematic comparative study of in vitro differentiation conditions has been performed for murine FGSCs (mFGSCs). MATERIALS AND

methodsmFGSCs line was cultured under five different conditions for in vitro differentiation. RT-PCR was performed to detect the expression of Oct4, Fragilis, Blimp1, Mvh, Scp3 and Zp3. Immunofluorescence was carried out to test the expression of Mvh, Fragilis and Zp3. Two-photon laser-scanning microscope was used to analyze nucleus-plasma ratio, and the proportion of chromatin of GV oocytes differentiated from mFGSCs in vitro (IVD-GVO), GV oocytes from in vivo (GVO) and mFGSCs.

resultsRT-PCR and immunofluorescence showed that mFGSC line expressed germ cell-specific markers, but not a meiosis-specific marker. By evaluating five different in vitro differentiation conditions, condition 5, which included a hanging drop procedure and co-culture of mFGSCs with granulosa cells, was shown to be optimal. mFGSCs could be successfully differentiated into germinal vesicle (GV) -stage oocytes under this condition. 3D observation revealed that both the nucleus-plasma ratio and proportion of chromatin were not significantly different between IVD-GVO and GVO.

conclusionWe evaluated five in vitro differentiation conditions for mFGSCs and successfully differentiate mFGSCs into GV-stage oocytes using a three-step differentiation process.
