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

backgroundCurrently, scientists are looking for a solution to the problem of the couples who have a lack of germ cells by through cell therapy. It is found that human amniotic membrane mesenchymal stem cells (hAMSCs) could be a good candidate for solving this problem. In the present study, an attempt was made to show that hUMSCs can express the PGC markers in the presence of retinoic acid (RA).

methodsPlacenta was obtained from healthy mothers and amniotic stem cells were isolated by enzymatic method from amniotic membrane. The cells were treated by retinoic acid for 14 days. Mesenchymal properties of hAMSCs were assessed by flow-cytometry and expression of PGC markers was established by Q-PCR.

resultsMesenchymal stem cell properties were confirmed by antibodies against mesenchymal stem cell markers (CD73, CD90, and CD105). After that, the expression of the C-kit, Oct4, SSEA4, VASA genes were determined as primordial germ cell markers using quantitative PCR. It was found that the use of retinoic acid led to the highest expression of C-kit, SSEA4, VASA genes and lower expression of Oct4.

conclusionOur study indicates that retinoic acid can be used as a suitable factor for induction of hAMSCs into primordial germ cells (PGCs) and hAMSCs have enough potential to do that.
