Résumé
Aggregate cultures of mixed glial cells, as well as of enriched astrocytes and oligodendrocytes were prepared, and maintained in serum-free medium for up to 25 days. Biochemical measurements of both neuron-specific and glia-specific enzyme activities showed that these three types of aggregate cultures were virtually devoid of neurons. Astrocyte-enriched cultures were greater than 95% pure, with oligodendrocytes as the only apparent contaminant, whereas oligodendrocyte-enriched cultures still contained a considerable proportion of astrocytes. In all these neuron-free aggregate cultures both astrocytes and oligodendrocytes attained a high degree of maturation. These findings were confirmed by morphological examinations, and by immunofluorescence studies. Furthermore, ultrastructural as well as immunocytochemical investigations using antibodies to myelin basic protein revealed that all three types of glial cell aggregate cultures contained myelin membranes, indicating that the presence of axons is not a prerequisite for the formation of myelin.
