A novel population of extracellular vesicles smaller than exosomes promotes cell proliferation.
Article in Cell communication and signaling : CCS, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 51 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
backgroundExtracellular vesicles (EVs) play important roles in intercellular communication by delivering RNA, lipid, and proteins to neighboring or distant cells. Identification and classification of EVs secreted from diverse cell types are essential for understanding their signaling properties.
methodsIn this study, EVs from the culture media were isolated by ultracentrifugation and analyzed by electron microscopy (EM) and nanoparticle tracking analyses. Conditioned media (CM) from HEK293 cells culture grown either in serum-free (SF) or 10% fetal bovine serum (FBS) containing media were centrifuged at 100,000×g to separate the SN
resultsWe identified a new group of EVs in the P200 fraction that was smaller than exosomes in size. Typical exosome markers such as Hsp70, TSG101, and CD63 were found in both P100 exosomes and the P200 vesicles, but CD81 was highly enriched in exosomes but not in the P200 vesicles. Furthermore, chemicals that inhibit the major exosome production pathway did not decrease the level of P200 vesicles. Therefore, these small EVs indeed belong to a distinguished group of EVs. Exosomes and the P200 vesicles were found in CM of human cell lines as well as FBS. Addition of the exosomes and the P200 vesicles to human cell cultures enhanced exosome production and cell proliferation, respectively.
conclusionsOur study identifies a novel population of EVs present in the P200 fraction. This EV population is distinguished from exosomes in size, protein contents, and biogenesis pathway. Furthermore, exosomes promote their own production whereas the P200 vesicles support cell proliferation. In sum, we report a new group of EVs that are distinct physically, biologically and functionally from exosomes.
