Stem Cell Mobilization

Fight Aging!

Do you want to live a longer life in good health? Simple practices can make some difference, such as exercise or calorie restriction. But over the long haul all that really matters is progress in medicine: building new classes of therapy to repair and reverse the known root causes of aging. The sooner these treatments arrive, the more lives will be saved. Find out how to help »

myDNA notes that "scientists have discovered how blood-regenerating stem cells move from bone marrow into the blood stream. The finding has led to the development of a new chemical compound that can accelerate this process (called stem cell mobilization) in mice - which could eventually lead to more efficient stem cell harvesting for human use." One reason researchers are searching for other sources of multipotent stem cells is that bone marrow extraction is an unpleasant, expensive procedure. Making bone marrow stem cells come out for convenient collection from blood is an intriguing alternative to attempting to use skin or fat stem cells, for example.
