Midkine gene transfer protects against focal brain ischemia and augments neurogenesis.

Background And Purpose: Midkine is a heparin-binding growth factor having various biological activities including chemotaxis of inflammatory cells, angiogenesis and migration of neuronal cells. These biological activities are expected to have a great impact on the pathology of brain infarction in subacute phase. Therefore, we investigated the effect of post-ischemic gene transfer of midkine in the phase.
