Tracing the development of oligodendrocytes from precursor cells using monoclonal antibodies, fluorescence-activated cell sorting, and cell culture.
We have used antibody and complement-mediated cell killing, fluorescence-activated cell sorting and tissue culture to study the development of rat oligodendrocytes. We show that (1) three ligands that bind to the majority of CNS neurons (the monoclonal antibodies A4 and A2B5 and tetanus toxin) also bind to immature oligodendrocytes and to precursor cells in 14-day embryonic rat brain that develop into oligodendrocytes in vitro; and (2) precursor cells in 17- to 18-day embryonic rat optic nerve can develop into oligodendrocytes in vitro in the absence of living neurons.
