Neural Stem Cells
When neural stem cells are isolated from the brain and cultured, they form spheres, made up of cells at different stages of differentiation. These NEUROSPHERES provide scientists with tools to study these stem cells outside the brain. Only a small percentage of the cells in a neurosphere are actually stem cells.
