* Because the presence of tumor-associated macrophages (TAMs) in bone tumors has been shown to be potentially associated with survival time, the Flint Animal Cancer Center at Colorado State University is conducting a study to develop a noninvasive way to determine how many TAMs are present in bone tumors through the use of an Ultra-Small Paramagnetic Iron Oxide Particle MRI for Imaging.

The team, led by Rex Moats, PhD, and Karen Aboody, MD, said their method, which involves "pre-loading" the cells before transplantation with ultra-small, super paramagnetic iron oxide nanoparticles that can then be detected via magnetic resonance imaging (MRI), has been approved for clinical trials in humans and has the potential to greatly accelerate the search for new treatments for deadly brain tumors and other diseases.
