The cells in a glioma look similar to healthy brain cells called glial cells. Glial cells surround nerve cells and help them function. As a glioma grows it forms a mass of cells called a tumor. The tumor can grow to press on brain or spinal cord tissue and cause symptoms.One of the landmark events of the past 25 years in neuroscience research was the establishment of neural stem cells (NSCs) as a life-long source of neurons and glia, a concept that shattered the dogma that the nervous system lacked regenerative power. Stem cells afford the plasticity to generate, repair, and change nervous system function.
