Summary:
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. Within weeks of a stroke, new blood vessels begin to form, and newly born neurons migrate long distances to the damaged area to aid in the regeneration process of the brain. Using the mouse model, UCLA neurologists have identified the cellular cues that start this process, thus casually linking angiogenesis, the development of new blood vessels, and neurogenesis, the birth of new neurons.
