A translational mouse model for investigation of the mechanism of preterm diffuse white matter injury.

ABSTRACT:

Background

The increasing incidence of preterm birth has led to a global problem of adverse neurodevelopmental outcomes in preterm neonates as a result of brain injury. There is still a lack of models mimicking diffuse white matter injury (WMI) in preterm neonates that can be applied to transgenic mice.

Methods

The right common carotid artery of the neonatal mouse was ligated on postnatal day 3 (P3) C57BL/6 mice and followed by 80, 90, or 100 min of hypoxia using a mixture of 10%±0.2% oxygen-nitrogen. The most suitable model was chosen by characterizing the effects of this hypoxic-ischemic insult on development of myelin, glial cell conditions, and neurological outcomes by hematoxylin-eosin (HE) staining performed at postnatal day 17 (P17), western blot measuring myelin basi
