Injections of a stimulant agent into rat brains expanded blood vessels and improved blood flow, a finding that may lead to a new, non-invasive way to prevent stroke, researchers reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.
Rats treated with the growth-promoting substance granulocyte macrophage-colony stimulating factor (GM-CSF) had almost twice as much arteriogenesis, the expansion of a brain artery, after one week compared to rats given saline solution. The increase was associated with improved circulation and accumulation of cells that are thought to play a key role in artery development.
“To the best of our knowledge, this is the first report of stimulation of arteriogenesis in the brain,” say co-lead authors Ivo R. Buschmann, M.D., and Hans-Jörg Busch, M.D. Both are investigators in the Research Group for Experimental and Clinical Arteriogenesis at Albert Ludwigs University in Freiburg, Germany.
