Super homotypic targeting by surface engineering of extracellular vesicles.
Article in Nature biomedical engineering, 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
Homotypic targeting is the inherent ability of cells to preferentially interact with cells of the same type, a phenomenon seen in cell adhesion, tissue formation and immune responses. However, its potential remains underexploited. Here we report a strategy to substantially enhance homotypic targeting through extracellular vesicles secreted by cells. By engineering the surface of small extracellular vesicles (sEVs) with lanthanides, we amplify specific cell-sEV interactions by more than 25-fold, enabling the selective capture of sEVs by cells of the same lineage even in the presence of excess off-target sEVs. We term this effect 'super homotypic targeting'. Super homotypic targeting provides a means to distinguish sEVs of different origins within highly heterogeneous sEV populations and enables two applications: using cells to detect specific sEVs and using sEVs to detect specific cells, specifically demonstrated here in the context of cancer detection from blood samples. Super homotypic targeting could hold potential for diagnostics, immunotherapy, drug delivery, rejuvenation and tissue engineering.
