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

backgroundOrganoids derived from induced pluripotent stem (iPS) or embryonic stem (ES) cells have been evaluated as in vitro models of development and disease. However, maintaining these cells under long-term static culture conditions is difficult because of nutrition shortages and waste accumulation. To overcome these issues, perfusion culture systems are required for organoid technology. A system with a stable microenvironment, nutrient availability, and waste removal will accelerate organoid generation. The aim of this study was to develop a novel perfusion system for renal organoids by maintaining the air-liquid interface with a device fabricated using a 3D printer.

resultsOur results revealed slow flow at the organoid cultivation area based on microbead movement on the membrane, which depended on the perfusion rate under the membrane. Moreover, the perfused culture medium below the organoids via a porous membrane diffused throughout the organoids, maintaining the air-liquid interface. The diffusion rates within organoids were increased according to the flow rate of the culture medium under the membrane. The perfused culture medium also stimulated cytoskeletal and basement membrane re-organization associated with promotion tubular formation under 2.5 μL/min flow culture. In contrast, tubules in organoids were diminished at a flow rate of 10 μL/min.

conclusionsOur liquid-air interface perfusion system accelerated organization of the renal organoids. These results suggest that suitable perfusion conditions can accelerate organization of epithelial cells and tissues in renal organoids in vitro.
