Scientists discover a dynamic cellular defense against breast cancer invasion

(Johns Hopkins Medicine) Johns Hopkins researchers report they have demonstrated in mouse tissue grown in the lab that the cell layer surrounding breast milk ducts reaches out to grab stray cancer cells to keep them from spreading through the body. The findings reveal that this cell layer, called the myoepithelium, is not a stationary barrier to cancer invasion, as scientists previously thought, but an active defense against breast cancer metastasis.
