From time to time we invite patients or patient advocates to post a guest blog on the Stem Cellar. Today we are featuring Brigitta Burguess, a mother and writer from Michigan, who focuses on pregnancy, parenting, and children with disabilities. Brigitta writes for the HIE Help Center, a website that offers information and supportive resources for families of children with disabilities.
Because stem cells are the building blocks of the immune system, they possess the ability to develop into other types of cells. You can use stem cells to help repair tissues, organs, and blood vessels, and even treat a host of different diseases. This is done through stem cell harvesting and stem cell therapy. In stem cell therapy, stem cells are injected into injured tissues in the hopes of replacing damaged tissue and preserving existing tissues.
Every part of the human body contains stem cells. However, many areas of the body do not contain enough stem cells to make harvesting them worthwhile. Cord blood, the leftover blood collected from a baby’s umbilical cord or a mother’s placenta after birth, is especially beneficial because:
- It provides a rich source of stem cells that can be changed into other types of cells and help to maintain and repair tissues
- Its stem cells are immature and have not developed the ability to attack foreign cells, which makes them perfect for transplant
- Its stem cells differ from embryonic stem cells in that they are considered adult stem cells and do not require the destruction of an embryo to harvest
- It can be used to treat blood disorders, immune deficiencies, and certain cancers
- Storing cord blood can help family and community members receive gene therapy treatment for the aforementioned conditions and diseases
The Applications of Stem Cell Therapy for Kids
Today, over 2,000 total cord blood stem cell transplants are performed annually, with the total number of cord blood banks worldwide reaching over 150. The innovations in stem cell therapy have made waves over the past four decades. Today, more than 80 difference diseases are being treated with cord blood stem cells.
In 2012, many clinical trials revealed that cord blood transplants were an effective treatment for cerebral palsy. Researchers also believe that cord blood stem cells have great potential in treating the neonatal brain injuries such as hypoxic-ischemic encephalopathy (HIE). As of right now, there is no indication that stem cell therapy can cure these conditions, but there is some evidence that it can lessen the severity of symptoms.
It is important to note that there is thus far no cure for hypoxic-ischemic encephalopathy (HIE) and resulting motor, cognitive, and/or intellectual disorders. Stem cell therapy seeks to limit the damage caused by HIE and reduce the severity of disabilities caused by HIE, but it is not a cure.
Because stem cell therapy is still in clinical trials, parents should think twice before going down this untested path, as no formal guidelines about administration protocol, dosages, safety, or treatment timeline have yet been established. Clinical trials are important for ensuring that treatments are safe and effective – unregulated treatments bear significant risk.
