Stem-cell-based therapy promising for treatment of breast cancer metastases in the brain

April 24, 2015

Investigators from Massachusetts General Hospital (MGH) and the Harvard Stem Cell Institute have developed an imageable mouse model of brain-metastatic breast cancer and shown the potential of a stem-cell-based therapy to eliminate metastatic cells from the brain and prolong survival. The study published online in the journal Brain also describes a strategy of preventing the potential negative consequences of stem cell therapy.

"Metastatic brain tumors - often from lung, breast or skin cancers - are the most commonly observed tumors within the brain and account for about 30 percent of metastases," says Khalid Shah, MS, PhD, director of the Molecular Neurotherapy and Imaging Laboratory in the MGH Departments of Radiology and Neurology, who led the study. "Our results are the first to provide insight into ways of targeting with stem-cell-directed molecules that specifically induce the death of tumor cells and then eliminating the therapeutic ."
