VEGF-A and the corresponding receptors are rapidly up-regulated after traumatic injury of the central nervous system (CNS). VEGF-A is highly expressed in the acute and sub-acute stages of CNS injury, but the protein expression declines over time. This time-span of VEGF-A expression corresponds with the endogenous re-vascularization capacity after injury.  This would suggest that VEGF-A / VEGF 165 could be used as target to promote angiogenesis after traumatic CNS injuries. However, there are contradicting scientific reports about the effects of VEGF-A treatments in CNS injury models.
