Predicting Nanotube Fibrogenicity through Stem Cell-Mediated Fibroblast Focus and Spheroid Formation.
Article in Nano letters, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Fibroblast stem cells or stemlike cells (FSCs) are proposed to play a pivotal role in extracellular matrix (ECM) regeneration by serving as a key source of ECM-producing fibroblasts. We developed a mechanism-based in vitro model for fibrogenicity testing of nanomaterials based on their ability to induce FSCs. Using a FSC-enriched fibroblast focus model to mimic in vivo fibrogenic response, we demonstrated a dose-dependent increase in fibroblast focus formation and collagen production by primary lung fibroblasts treated with multiwalled carbon nanotubes (MWCNTs). The focus-forming cells exhibited stem properties as indicated by stem cell markers expression, sphere formation, and ALDH activity assays. Inhibition of ALDH activity diminished the focus and sphere formation as well as collagen production. In vivo animal studies supported the in vitro findings and indicated the potential utility of FSC-based assays as a rapid screening tool for fibrogenicity testing of nanomaterials. This study also unveils a novel mechanism of nanotube-induced fibrogenesis through ALDH-dependent FSC activation.
