COVER Early (green) and mature (magenta) oligodendrocytes purified from the early postnatal mouse brain. These myelin-producing cells of the central nervous system belong to a highly complex group of cells known as glia, which are involved not only in the conduction of action potentials along neuronal axons, but also in the development of synapses and in immune processes in the nervous system.
