Hou J, et al. - The researchers investigated the functions of salivary adenoid cystic carcinoma-derived (SACC-derived) tumor-derived exosomes (TDE) in SACC progression and examined potential mechanisms. In this study, they suggested that SACC cells-derived exosomes were loaded with individual components that could enhance invasiveness and induce microenvironment changes. Therefore, promoting SACC aggression.
