General description
Oligodendrocytes and astrocytes are derived from common precursor cells, glioblasts (Sommer, 1981). O-Antigens are sulfatides, which function as differentiation markers on the surface of oligodendrocytes of the central nervous system. O4 is formed postnatally (Schachner, 1981) and is a marker for cell bodies and processes of oligodendrocytes types I and II (hairy eyeball type). During oligodendrocyte differentiation, O4 occurs in pro-oligodendrocytes, but not in O-2A-progenitor cells. O4 occurs from day 3 onwards in cell cultures of embryonic mouse brain. Anti-O4 can be used in myelination, demyelination and remyelination studies and in regeneration experiments.
