Every cell in a human brain contains the same sequence of DNA, but in different cell types different genes are copied onto strands of RNA for use as protein blueprints. This ultimate variation in which proteins are found in which cells—and at what levels—allows the vast diversity in types of brain cells and the complexity of the brain.

Such elements are compelling candidates for cell-type-specific enhancers to drive expression of genetic tools in specific subsets of brain cells and may also help narrow the search for causative alleles at specific genetic risk loci. Finally, as in vitro models of complex brain tissues become more sophisticated

Glioma is a growth of cells that starts in the brain or spinal cord. 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.
