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

purposeTo explore the in vitro 3D culture of ovarian tissue thawed in two different ways with TISSEEL Fibrin and assessed transcriptome differences by RNA sequencing.

methodsHuman ovarian tissue samples were collected, and the fragments used for the experiments were obtained from tumor patients involved in a fertility treatment program. After cryopreservation (frozen and thawed after initial cryopreservation), with or without 3D culture with TISSEEL Fibrin. The culture flask is agitated at 75 times per minute using a rotary shaker during the entire culture process. Four experimental groups were formed. Frozen tissue after quick thawing at 100 °C (Group 1), frozen tissue after quick thawing at 100 °C and in vitro 3D culture for 7 days with TISSEEL Fibrin (Group 2), frozen tissue after slow thawing at 37 °C (Group 3), frozen tissue after slow thawing at 37 °C and in vitro 3D culture for 7 days with TISSEEL Fibrin (Group 4). All groups were followed by RNA sequencing and histological evaluation.

resultsHematoxylin-eosin (HE) staining has shown that the follicle cells have the tendency to develop and actively migrate into the fiber. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis shows that in comparison to groups 1 and 3 (thawing ovarian tissue without culture), Differential Expression Genes (DEGs) in groups 2 and 4 (thawing ovarian tissue with in vitro 3D culture), are mainly enriched and up-related in the lysosome pathway and protein processing in the endoplasmic reticulum pathway and mainly down-related in the cell adhesion molecules pathway.

conclusionsThe technology of the described dynamic in vitro 3D-cultivation of ovarian tissue for 7 days with TISSEEL Fibrin is informative and demonstrates that it may promote follicular growth, actively migrate into the fiber, weaken cell adhesion, and cause little cell damage.
