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

backgroundHuman amniotic epithelial cell (hAEC) transplantation holds great promise in treating premature ovarian insufficiency (POI). However, some deficient biological characteristics of hAECs restrict their application.

methodsVitamin C (VC) was added to the culture media of hAECs for 2 weeks. Then, the proliferative ability, migration ability, pluripotency, and self-renewal of VC-treated hAECs (VC-hAECs) were determined. Next, hAECs and VC-hAECs were transplanted into the ovaries of cyclophosphamide (CTX)-induced POI model mice. The ovarian function of POI mice was evaluated after transplantation by counting follicle numbers and measuring the blood levels of AMH, E2, and FSH. The rescue effects of VC-hAECs and hAECs were unveiled by coculturing with CTX-damaged human ovarian granulosa cells (hGCs) and analyzing relative marker expression. Additionally, ovarian marker expression and transplant survival were detected in POI mice after transplantation to verify the beneficial effect of VC-hAECs. The cytokine profiles of VC-hAECs and hAECs were revealed by performing a cytokine array and an ELISA to show their paracrine function.

resultsOur results indicated that VC promoted the proliferation, migration, pluripotency, and self-renewal of hAECs in vitro. The most effective concentration of VC was 50 μg/ml. After transplantation into the POI mouse model, VC-hAECs reversed ovarian function more powerfully than hAECs. Human granulosa cell marker expression in CTX-damaged hGCs was increased after coculture with VC-hAECs compared with hAECs. In the ovaries of the POI mice, ovarian marker expression was greater after VC-hAEC transplantation than after hAEC transplantation. VC-hAECs showed higher transplant survival than hAECs. Furthermore, VC-hAECs secreted more growth factors than hAECs.

conclusionTreatment with VC promoted the proliferation, migration, self-renewal, and paracrine functions of hAECs. Additionally, VC elevated the therapeutic potential of hAECs in treating POI.
