Aggressive Brain Tumors Can Originate from a Range of Nervous System Cells

Scientists have long believed that glioblastoma multiforme, the most aggressive type of primary brain tumor, begins in glial cells that make up supportive tissue in the brain or in neural stem cells. Researchers found that the tumors can originate from other types of differentiated cells in the nervous system, including cortical neurons.

Astrocytes Control the Generation of New Neurons from Neural Stem Cells

Neuroscience researchers show how astrocytes control the generation of new neurons in the brain. “In the brain, astrocytes control how many new neurons are formed from neural stem cells and survive to integrate into the existing neuronal networks. Astrocytes do this by secreting specific molecules but also by much less understood direct cell-cell interactions with stem cells”, says Prof. Milos Pekny.

Study Pinpoints a Genetic Cause of Most Lethal Brain Tumor and May Lead to New Treatment

Researchers discovered that some cases of glioblastoma, the most common and aggressive form of primary brain cancer, are caused by the fusion of two adjacent genes. The study also found that drugs that target the protein produced by this genetic aberration can dramatically slow the growth of glioblastomas in mice.
