Cell Culture Substrate Variation Alters Extracellular Vesicle Biogenesis Without Affecting Non-Coding Repeat RNA Profile.
Article in Small (Weinheim an der Bergstrasse, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Tissue stiffening is central to disease progression and aggressiveness in pancreatic adenocarcinoma (PDAC). Here we report how the biomechanical characteristics of the cell culture conditions impact the amount, as well as the cargo, of extracellular vesicles (EVs) produced by pancreatic cancer cells. Cells grown on softer matrices (0.5 kPa) release upwards of 40 times more EVs than those grown on stiffer surfaces (8 kPa) and their cargo is more enriched in protein-coding RNAs related with mitochondrial and cytoskeleton pathways. Moreover, cells grown in a 3D conformation release more EVs than those grown in 2D, with the repeat RNA content being maintained across all different cell culture conditions. Our study provides evidence to support that the mechanical microenvironment of cells influences EV generation, with distinct consequences for coding and non-coding RNA packaged within the EVs.
