Article Title: ADAM10 tailors extracellular vesicles for content transfer rather than signaling by contact

doi: 10.64898/2026.02.12.705562

Figure Lengend Snippet: A. Summary table presenting the proteins identified and quantified by mass spectrometry analysis of ADAM10-KO cell lysates compared to control MCF7 cells and their corresponding secreted sEVs. B-C. sEVs secreted by MCF7 cells with knock-out of ADAM10 (A10 KO) or control cells (WT) were isolated by differential ultracentrifugation of conditioned culture media. Cell lysates and sEVs were analyzed by Western blot, testing for several proteins including EphrinB3, BCAM, E-cadherin and PTK7 ( B ), SRC ( C ). Histograms represent mean signal intensities normalized to controls ± SEM, calculated from n independent experiments. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001, n.s. non-significant (multiple unpaired t-test).
