Stem cells lurking in tumors can resist treatment​​​​

Scientists are eager to make use of stem cells’ extraordinary power to transform into nearly any kind of cell, but that ability also is cause for concern in cancer treatment. New research at the School of Medicine has revealed that these stem cells are present even in slow-growing, less aggressive tumors.

New clue to aggressive brain tumors

Scientists at the School of Medicine have identified a biological marker that may help predict overall survival of people with deadly brain tumors. The marker is made by noncancerous cells known as monocytes (pictured in brown).

Brain scans reveal drugs’ effects on attention

Scientists have developed a way to evaluate new treatments for some forms of attention deficit disorder. Working in mice, researchers at the School of Medicine showed that they can use brain scans to quickly test whether drugs increase levels of dopamine. The same group found that raising dopamine levels in mice alleviates attention deficits caused by neurofibromatosis type 1 (NF1), a condition that affects more than 100,000 people in the United States.
