Radial glia
Radial Glia
Radial glia (pronounced: /ˈreɪdiəl ˈɡliːə/) are a type of glial cell that serve as neuronal progenitor cells and a scaffold for neuronal migration in the developing nervous system.
Etymology
The term "radial glia" is derived from the Latin radius, meaning "spoke of a wheel" or "ray", and the Greek glia, meaning "glue". This refers to the radial glia's role in providing structural support and guidance for neurons during development.
Function
Radial glia are crucial for the proper development of the brain and spinal cord. They serve as a scaffold for migrating neurons, guiding them to their correct locations in the developing nervous system. In addition, radial glia can divide to produce new neurons and other types of glial cells, including astrocytes and oligodendrocytes.
