Seeing is believing: Observation of migrasomes

Migrasomes, novel organelles first reported by Professor Li Yu' s team in 2015, are vesicular structures with diameters ranging from 0.5 to 3 micrometers that form on the retraction fibers at the rear of migrating cells. These structures contain various biomolecules such as proteins, nucleic acids, and lipids, along with numerous small vesicles, each approximately 50 nanometers in diameter.
