An epigenetically distinct breast cancer cell subpopulation promotes collective invasion

Abstract excerpt

Tumor cells can engage in a process called collective invasion, in which cohesive groups of cells invade through interstitial tissue. Here, we identified an epigenetically distinct subpopulation of breast tumor cells that have an enhanced capacity to collectively invade. Analysis of spheroid invasion in an organotypic culture system revealed that these "trailblazer" cells are capable of initiating collective...
