Representative cryo-electron microscopy image of the leading edge of a RAT-1 cell cultured on cryo-EM grids. Lamellipodia and filopodia in the upper right corner delineate the cell border, separating the cytoplasm (Cyt) from the extracellular space (Ext). Vesicular organelles are highlighted in color: early endosome-like vesicles (En, pink), multivesicular bodies (MVB, blue), hemifusomes (HF, yellow), and flipped hemifusomes (fHF, green). Scale bar - 0.5 µm. Image credit: Tavakoli et al., doi: 10.1038/s41467-025-59887-9.
