A glioblast is a type of cell located in the embryonic neuroectoderm that has the ability to differentiate into several different types of neuroglia through asymmetric cell division.[1]
It comes from a precursor (spongioblast). However, the latter may also differentiate into an ependymoblast.
Glioblasts differentiate into astrocytes and oligodendrocytes.[2] Its tumor is called a glioblastoma, and is the most common type of central nervous system malignancy.[3]
