Clarifying the Meaning of Stem Cell Preservation
Mention the term stem cell preservation to a crowd and you could be met with any number of responses anywhere from the admittedly uninformed, to the up-to-the-minute reader of the latest headlines on the subject. Mention the term cord blood to the same group and most folks would respond by saying, “What”? How ironic that one of the easiest ways to contribute to the health and well-being of society is still largely unknown. How wonderful that the life giving gift of stem cell preservation is one that begins with the miracle of birth.
Stem Cell Preservation – Defined
Stem cell preservation is the gathering and saving of nutrient rich stem cells that are present in the body, especially the umbilical cord at birth. One immediate question you might have is why are stem cells so valuable? Importantly, stem cells are highly adaptable and can readily replicate into red blood cells, white blood cells, and platelets. Red blood cells are important because they carry oxygen to all the cells in the body; white blood cells are responsible for fighting infection; and platelets aid in clotting when the body is injured. These components are the basic elements of healthy blood and a strong immune system.
Stem Cell Preservation – Going to the Source
After knowing what “stem cell preservation” is and why it is valuable, we ask the next question – where do we find stem cells? Modern medicine names three primary sources: the fertilized embryo, within bone marrow, and within the blood of an umbilical cord. In the first instance, there’s a great deal of controversy from an ethical standpoint. In the second there is a reasonably high level of risk, and in the third there are no ethical concerns and no real risk to mother or newborn.
For years, bone marrow transplants have been a common practice yielding somewhat inconsistent results in the treatment for certain kinds of cancers and leukemia. The number one challenge of this treatment, though, is the need for donor and recipient to be an exact marrow match. On the other hand, with cord blood treatments, the need for an exact match does not exist as the stem cells drawn from cord blood are more adaptable. This unique usefulness places a high level of importance on effective stem cell preservation.
Cord Blood – The Simplest Source
Stem cell preservation as it relates to umbilical cord blood is fairly simple, albeit somewhat futuristic sounding. Shortly after the birth of your newborn, his or her umbilical cord is clamped and cut; blood is drawn and transported to a lab where it is cryogenically frozen at temperatures in the neighborhood of -190 degrees. There is no risk to mom and baby and the transfer to a state of preservation is safe and exact.
Currently, stem cells are for the most part utilized in transplant medicine to regenerate a patient’s blood and immune system after they have been treated with chemotherapy and/or radiation to destroy cancer cells. Other more dynamic treatments are envisioned for the future as cord blood holds a very important place in stem cell preservation. Mother’s and their newborns are contributing to one of the most promising advances in medical technology everyday with the simple and safe methods of stem cell preservation.
