Adult stem cells, similar to embryonic stem cells, have the ability to differentiate into more than one cell type, but unlike embryonic stem cells they are often restricted to certain lineages.
Well over 1 million patients worldwide have been treated with adult stem cells and experienced improved health, based on data gathered by December 2012. Nearly 70,000 adult stem cell transplants were performed worldwide in 2012 alone. Nearly 20,000 adult stem cell transplants were performed in the United States in 2014 alone.
Currently, blood stem cells are the only type of adult stem cell used regularly for treatment; they have been used since the late 1960s in the procedure now commonly known as bone marrow transplant.Transplants of neural stem cells have been tried in small numbers of patients with brain disorders such as Parkinson disease, and the FDA recently approved a clinical trial of neural stem .
Stem cell therapy used to involve embryonic cells, which understandably generated a lot of controversy. Today’s research focuses on non-embryonic adult mesenchymal stem cells—and there is nothing controversial about using your own cells in a safe and therapeutic manner. Adult stems cells may be derived from bone marrow.
