Scientists at Cold Spring Harbor Laboratory (CSHL) report that two different mouse models of breast cancer progressed differently based on characteristics of the tumor microenvironment, which is the area of tissue in which the tumor is embedded. The team published its study (“Presence of Insulin-Like Growth Factor Binding Proteins Correlates With Tumor-Promoting Effects of Matrix Metalloproteinase 9 in Breast Cancer”) in Neoplasia.
