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

In vitro models of the small intestine are crucial tools for the prediction of drug absorption. The Caco-2 monolayer transwell model has been widely employed to assess drug absorption across the intestine. However, it is now well-established that 3D in vitro models capture tissue-specific architecture and interactions with the extracellular matrix and therefore better recapitulate the complex in vivo environment. However, these models need to be characterized for barrier properties and changes in gene expression and transporter function. Here, we report that geometrically controlled self-assembling multicellular intestinal Caco-2 spheroids cultured using Sacrificial Micromolding display reproducible intestinal features and functions that are more representative of the in vivo small intestine than the widely used 2D transwell model. We show that Caco-2 cell maturation and differentiation into the intestinal epithelial phenotype occur faster in spheroids and that they are viable for a longer period of time. Finally, we were able to invert the polarity of the spheroids by culturing them around Matrigel beads allowing superficial access to the apical membrane and making the model more physiological. This robust and reproducible in vitro intestinal model could serve as a valuable system to expedite drug screening as well as to study intestinal transporter function.
