Extracellular vesicles (EVs) mediate intercellular communication by transferring signaling macromolecules. Unexpectedly, the author here identifies that adipocyte-specific loss of SMPD3 triggers neighboring preadipocytes to release EVs containing SMPD3 mRNA, restoring SMPD3 expression in genetically null adipocytes.
