Abstract
We found that transient hypoxia at P7 altered the expression of Ascl1, Olig1 and Nkx2.2, resulting in delayed myelination in the external capsule. In addition, our study showed that oligodendrocyte progenitor cells specified several days prior to a hypoxic event are more susceptible to maturation arrest than those specified shortly prior to hypoxia. Our results suggest that alterations of Ascl1, Olig1 and Nkx2.2 underlie impaired oligodendrocyte differentiation and deficient myelination in WMI. These transcription factors are potential therapeutic targets for the treatment of WMI in preterm infants.
