A primary culture method for the easy, efficient and effective acquisition of oligodendrocyte lineage cells

Abstract

Oligodendrocytes (OL) are myelin forming glial cells in the central nervous system. In vitro primary OL culture models provide the benefit of a more readily controlled environment facilitating the evaluation of diverse OL stages and convoluted dynamics. Conventional methods of primary OL culture do exist, but their performance in terms of efficiency and simplicity has room for improvement. We present a novel method of primary OL culture, namely the E3 (Easy, efficient, and effective) method, which greatly improves cell yield and reduces time required to oligodendrocyte progenitor cell (OPC) acquisition and maturation into OLs. We also provide optimal media compositions for augmentation of OPC proliferation and a more robust maturation into myelin forming OLs. In vitro characteristics of the OL lineage discovered during the development of the E3 method present implications for further research on OL physiology and pathophysiology.
