Detection of Organelle-Specific Dyes Labeled Extracellular Vesicles with Colocalization-Fluorescence Nanoparticle Tracking Analysis.
Article in ACS omega, 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
Most cell types release a diverse array of extracellular vesicles (EVs) that contribute to intercellular communication. In particular, considering the heterogeneity of EVs, methods capable of identifying and measuring individual vesicles are limited. Here, we used fluorescence and colocalization Nanoparticle Tracking Analysis (NTA) to identify the subcellular origin of vesicles and determine their physical characteristics, as well as colocalization ratios of endoplasmic (ER) and Mitochondria (Mito) positive EVs in human choriocarcinoma cells (JAr) and bovine follicular fluids (BFF). The labeling efficiency for ER-labeled JAr EVs purified in SEC was 67.11 ± 25.40%, compared to 96.27 ± 13.72% of BFF EVs. Regarding Mito dye labeling efficiency, SEC-purified BFF EVs (14.21 ± 7.45%) provided lower Mito-positive fluorescent particles than JAr EVs (25.74 ± 4.46%). The proportion of CellMask Deep-Red (CMDR) membrane labeling of nanoparticles varied across JAr and BFF EVs. Furthermore, colocalization analysis of ER and Mito-dye-labeled JAr and BFF revealed potential intracellular interactions between organelles and the EV biogenesis pathways. The integration of novel colocalization technology into fluorescence-NTA (F-NTA) represents a significant advancement in the field of single EV particle analysis in deepening our understanding of EV biology.
