The long-standing mystery behind dormant disseminated breast tumor cells and what activates them after years and even decades of latency may have been solved. Researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have identified the microenvironment surrounding microvasculature – the small blood vessels that transport blood within tissues – as a niche where dormant cancer cells reside. When these blood vessels begin to sprout, the new tips produce molecules that transform dormant cancer cells into metastatic tumors.
