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

Human amniotic epithelial cells (hAECs) show similar features to stem cells and have low immunogenicity. This study aims to investigate the therapeutic effect of hAEC transplantation on cyclophosphamide-induced primary ovarian insufficiency (POI) rats and evaluate the underlying mechanisms by mRNA sequencing of ovarian samples. Notably, hAECs mainly located in the interstitial area of the ovaries rather than follicles. hAEC transplantation led to a slight increase in body and ovary weight, normalized irregular estrous cycles, decreased serum follicle stimulating hormone (FSH) and increased anti-Mullerian hormone (AMH) level and restored follicle pools in POI rats. Ovarian expression of AMH, follicle stimulating hormone receptor (FSHR) and klotho in POI rats was also significantly upregulated following hAEC transplantation. Fetus number was higher in the hAEC transplantation group than the POI group. The mRNA sequencing results showed that hAEC transplantation led to the upregulation of several angiogenesis and inflammation molecules including interferon regulatory factor 7 (IRF7), Mx dynamin-like GTPase 1 (Mx1), vascular endothelial growth factor receptor (VEGFR)1 and VEGFR2. Moreover, hAEC therapy had an effect on ribosomes, protein digestion, protein absorption, neuroactive ligand-receptor interaction, cAMP signaling pathway and steroid biosynthesis pathways. The expression of several steroid biosynthesis proteins was significantly upregulated as measured by quantitative real-time polymerase chain reaction (RT-qPCR), immunohistochemical staining and Western blot analysis. In summary, hAECs can significantly restore ovarian function, and improve both ovarian reserve and fertility. This may be due to the paracrine effect of hAECs in regulating steroid biosynthesis, modulating follicle development from initiation to ovulation, promoting angiogenesis and reducing inflammation.
