ARM Stroke
1 like471 views
Strokes are a leading cause of disability in the US, with 795,000 Americans suffering strokes each year. Strokes occur when blood flow to the brain is disrupted, damaging brain tissue. Currently, only limited emergency treatments are available within 3-4 hours of the stroke. Regenerative medicine therapies are bringing hope to repair stroke damage by using stem cells and other living cells and tissues. Several companies are studying therapies using mesenchymal stem cells, neural stem cells and placental cells. These therapies aim to regenerate damaged brain tissue and reduce disability after stroke.
