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

backgroundThin endometrium is a significant cause of infertility due to impaired regeneration, reduced receptivity, and insufficient angiogenesis. Mesenchymal stem cell-derived secretome (MSCsec) is a promising cell-free therapy because it contains bioactive molecules that promote tissue repair. This study evaluated the effects of Wharton's jelly-derived MSC secretome (WJ-MSCsec) on human endometrial stromal cells (EnSCs) and endothelial cells in vitro.

methodsWJ-MSCs were isolated from umbilical cord tissue, characterized, and cultured under serum-free conditions. The concentrated secretome was analyzed using a human angiogenesis proteome array. EnSCs were isolated from endometrial biopsies. EnSC proliferation and migration in the presence of WJ-MSCsec were assessed using CCK-8 and scratch wound-healing assays. Pro-angiogenic activity of WJ-MSCsec was evaluated using a Matrigel tube formation assay with human umbilical vein endothelial cells (HUVECs).

resultsProteomic analysis of WJ-MSCsec revealed the presence of angiogenic, mitogenic, immunomodulatory, and chemotactic factors. Treatment with WJ-MSCsec significantly enhanced EnSC proliferation and accelerated wound closure. Furthermore, WJ-MSCsec markedly promoted endothelial tube formation, increasing total tube length, junction number, and mesh formation.

conclusionsWJ-MSCsec stimulates EnSC proliferation and migration while enhancing angiogenesis in vitro. WJ-MSCsec represents a promising cell-free therapeutic strategy for endometrial regeneration and reproductive disorders associated with impaired endometrial function.
