Tel Aviv, Israel -- Israeli scientists say they have shown the viability of using bone marrow stem cells to treat such neurodegenerative diseases as Alzheimer's and Parkinson's.

Tel Aviv University researcher Yoram Cohen said he has proven the viability of the innovative stem cells, called mesenchymal stem cells, using in-vivo magnetic resonance imaging. Cohen said he tracked the stem cells progress within the brain, and initial studies indicate they can identify unhealthy or damaged tissues, migrate to them and potentially repair or halt cell degeneration.
