Myelination of central nervous system axons in tissue culture by transplanted oligodendrocytes
F Seil
and
NK Blank
Unmyelinated mouse cerebellar cerebellar cultures in which oligodendrocyte differentiation had been suppressed by exposure to cytosine arabinoside developed axonal myelin after superimposition of kainic acid-treated cerebellar explants devoid of myelin-receptive axons. The latter explants contained differentiated oligodendrocytes. The operation of a diffusible myelin-stimulating factor was ruled out by the failure of myelination in cytosine arabinoside-exposed explants not in direct contact with oligodendrocyte-containing transplants.
