Pros and Cons of Stem Cell Research – Where Do They Come From?
To understand the pros and cons of stem cell research, one must first understand where stem cells come from. There are three main sources for obtaining stem cells – adult cells, cord cells, and embryonic cells. Adult stem cells can be extracted either from bone marrow or from the peripheral system. Bone marrow is a rich source of stem cells. However, some painful destruction of the bone marrow results from this procedure. Peripheral stem cells can be extracted without damage to bones, but the process takes more time. And with health issues, time is often of the essence. Although difficult to extract, since they are taken from the patient’s own body, adult stem cells are superior to both umbilical cord and embryonic stem cells. They are plentiful. There is always an exact DNA match so the body’s immune system never rejects them. And as we might expect, results have been both profound and promising. Stem cells taken from the umbilical cord are a second very rich source of stem cells. Umb
To understand the pros and cons of stem cell research, one must first understand where stem cell come from. There are three main sources for obtaining stem cells – fully developed cells, cord cells, and embryonic cells. Adult stem cell can be extracted either from bone marrow or from the peripheral system. Bone marrow is a rich source of stem cells. However, some rough destruction of the bone marrow results from this procedure. Peripheral stem cells can be extracted without damage to bones, but the process take more time. And with health issues, time is often of the essence. Although difficult to extract, since they are taken from the patient’s own body, fully fledged stem cells are superior to both umbilical cord and embryonic stem cells. They are plentiful. There is always an exact DNA game so the body’s immune system never rejects them. And as we might expect, results have been both profound and promising. Stem cells taken from the umbilical cord are a second extraordinarily rich so
