Abstract Background and purpose: The endocannabinoid system has been involved in the modulation of neural stem cells proliferation, survival and differentiation as well as in the generation of new oligodendrocyte progenitors in the postnatal brain. The present work aims to test the effect of the synthetic Type 1 and Type 2 cannabinoid receptor agonist WIN55212-2 on these processes in the context of neonatal rat brain hypoxia-ischemia (HI). Methods: P7 Wistar rats were subjected to HI and treated either with WIN55212-2 (1 mg/kg) or vehicle twice daily for 7 days after HI and euthanized at 1, 2, 7, 14, or 28 days to explore white matter injury...
