Research Abstract

Circulating bone marrow-derived immature cells have been implicated in homeostasis of the microvasculature, and decreased levels of circulating endothelial progenitor cells, associated with aging, correlate with poor clinical outcomes in a range of cardiovascular diseases. We transplanted bone marrow cells from young stroke-prone spontaneously hypertensive rats (SHR-SP) into aged SHR-SP, and found that animals transplanted with bone marrow from young SHR-SP displayed an increase in density of the microvasculature in the periinfarction zone, reduced ischemic brain damage and improved neurologic function.
