From: Proteomic and metabolomic profiling of extracellular vesicles produced by human gut archaea
a, e, i, l Scanning electron micrographs of whole cells showing potential vesicle development on their cell surface. b, f, g, j, k Ultra-thin transmission electron micrographs of whole cells, highlighting vesicles located inside or attached to the cells. c, d, h, m Transmission electron micrographs of isolated vesicles. Arrows indicate the presence of archaeal extracellular vesicles (AEVs). The experiments were repeated two times independently with similar results. Source data are provided as a Source Data file.
