Tiny exports signal big shifts in cancer tissue, researchers find

Microscopic shifts in metabolism and increases in tiny transport vesicles out of tumor cells preface larger changes to the tumor environment and could prepare the way for cancerous cells to spread and metastasize, researchers report. They saw cancer-causing biological events at both the molecular and tissue scales as they happened, imaging the cells with precise wavelengths of light — no chemicals, dyes or genetic manipulation needed….
