A new study shows that melanoma-derived exosomes contribute to metastatic invasion by carrying messenger proteins that direct bone marrow–derived cells toward a prometastatic phenotype. This leads to the promotion of proangiogenic events and modification of the extracellular matrix at premetastatic sites (pages 883–891).
