We get asked this question a lot so it's not a problem, But stem cells do not come from aborted babies..We work with two kinds of stem cells. 1) Hematopoietic stem cells - These stem cells are derived from the patient's blood and bone marrow 2) Mesenchymal stem cells - These cells are derived from donated umbilical tissues, adipose tissue, etc. They have the added advantage of strengthening the body's immune response.
