Abstract/OtherAbstract:
Five immortalized oligodendrocyte cell lines, representing a spectrum of different stages of oligodendrocyte maturation, were transplanted into neonatal shiverer mouse brains and examined for their ability to survive, multiply, and migrate in vivo. Each of the cell lines migrated to different regions of the brain with remarkable consistency when injected into the mouse forebrain, suggesting that the cells might be responding to different environmental cues present in the neonatal mouse brain. These results are consistent with the fact that cells at different stages in the oligodendrocyte lineage probably possess different sets of surface molecules and receptors. Significant differences were also observed in the survival and proliferation of the lines examined, even when the lines tested had quite similar in vitro phenotypes. Interestingly, the cell line with the most mature in vitro phenotype, N20.1, appeared to elaborate membranous processes when transplanted into the brain, reminiscent of oligodendrocytes ensheathing axonal segments. The experiments suggest that these immortalized cells could be useful models to study the cellular and molecular mechanisms involved in the development, maturation and possibly formation of myelin by oligodendrocytes in the mammalian brain.
