Using 'off-the-shelf' engineered stem cell based therapy for treating glioblastomas post-surgery

Glioblastomas (GBMs) are highly aggressive cancerous tumors of the brain and spinal cord. Brain cancers like GBM are challenging to treat because many cancer therapeutics cannot pass through the blood-brain barrier, and more than 90 percent of GBM tumors return after being surgically removed, despite surgery and subsequent chemo- and radiation therapy being the most successful way to treat the disease.

Better understanding of hydrocephalus could lead to improved treatments

Hydrocephalus, or "water on the brain," occurs when the cerebral ventricles - four interconnected cavities of the brain that are filled with cerebrospinal fluid - become enlarged, but its cause is unknown in many cases.

Precise communication of two key memory regions boosts formation of lasting memories

In a new, rare study of direct brain recordings in children and adolescents, a Northwestern Medicine scientist and colleagues from Wayne State University have discovered as brains mature, the precise ways by which two key memory regions in the brain communicate make us better at forming lasting memories.

Researchers create a comprehensive atlas of cerebrovascular cell types

While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain.
