Abstract

The development of intravital microscopy has provided unprecedented capacity to study the tumor microenvironment in live mice. The dynamic behavior of cancer, stromal, vascular, and immune cells can be monitored in real time, in situ, in both primary tumors and metastatic lesions, allowing treatment responses to be observed at single cell resolution and therapies tracked in vivo. These features provide a unique opportunity to elucidate the cellular mechanisms underlying the biology and treatment of cancer. We describe here a method for imaging the microenvironment of subcutaneous tumors grown in mice using intravital microscopy.
