July is Cord Blood Awareness Month, a time to raise awareness about the importance of umbilical cord blood and its role in modern medicine. For expecting parents, learning about cord blood facts can help you understand why many families choose to preserve their baby’s cord blood after birth.

Umbilical cord blood contains valuable stem cells that are already being used in medical treatments around the world. Since the first successful cord blood transplant in 1988, when a young boy with Fanconi anaemia was treated using his newborn sibling’s cord blood, thousands of cord blood transplants have been performed worldwide.

If you are preparing for your baby’s arrival and exploring cord blood banking, these important cord blood facts can help you understand how cord blood is collected, stored, and why it may be valuable for your child and family.

Preserving Your Child’s Cord Blood Stem Cells is Painless and Risk-Free

One of the most important cord blood facts for expecting parents is that cord blood collection is simple, painless, and does not interfere with childbirth. After your baby is born and the umbilical cord is clamped and cut, the remaining cord blood inside the cord and placenta can be collected. Instead of being discarded as medical waste, this blood can be processed in a cord blood bank and cryogenically preserved for potential future use. The collection process does not harm the mother or baby. Cord blood banking simply preserves a resource that would otherwise be thrown away after birth.

Stem Cells from Cord Blood Have a Proven Track Record

Stem cells from umbilical cord blood have been used in medical treatments for more than 30 years. Since the first successful transplant, cord blood stem cells have helped treat thousands of patients worldwide.

Today, cord blood stem cells are used to treat more than 85 medical conditions, including blood disorders, cancers, immune system disorders, and metabolic diseases. Some conditions treated with umbilical cord blood stem cells include:

• Fanconi Anaemia
• Pure Red Cell Aplasia
• Acute Myelofibrosis
• Acute Lymphocytic Leukaemia (ALL)
• Ewing Sarcoma
• Hodgkin’s Lymphoma
• Congenital Neutropenia
• Congenital Erythropoietic Porphyria (Gunther Disease)
• Hunter Syndrome (MPS-II) and Hurler Syndrome (MPS-IH)
• Neuroblastoma
• Severe Combined Immunodeficiency (SCID)

Stem Cells from Umbilical Cord Blood Are More Likely to Be a Match

When a patient needs a stem cell transplant, doctors check compatibility between the donor and recipient through an HLA (Human Leukocyte Antigen) matching test. HLA markers help the immune system identify whether cells belong in the body or should be rejected. For bone marrow transplants, a close match is usually required to reduce the risk of rejection. Cord blood stem cells are considered more flexible because they are younger cells and are less likely to trigger a strong immune response. This means they may be accepted with a lower level of HLA matching compared with some other stem cell sources. This is one reason cord blood stem cells can be a valuable option for patients who need a transplant.

Umbilical Cord Blood Is a Diverse Source of Stem Cells

Umbilical cord blood contains several types of stem and progenitor cells, including:

• Haematological Stem Cells (HSCs)
• Mesenchymal Stem Cells (MSCs)
• Very Small Embryonic-Like Stem Cells (VSELs)
• Unrestricted Somatic Stem Cells (USSCs)
• Endothelial Colony-Forming Cells (ECFCs)
• Neuronal Progenitor Cells
• Multilineage Progenitor Cells (ML-PCs)

Researchers are still learning more about the different types of cells found in cord blood and their possible applications in medicine.

Your Child’s Stem Cells Are Especially Valuable for Your Child

Your baby’s own cord blood stem cells are a perfect biological match for them. This means there is no risk of rejection when using their own cells. Cord blood stem cells can also potentially benefit close family members. A sibling has about a 25% chance of being a full match, while parents may also have a chance of matching. This is why many families choose to preserve their baby’s cord blood as a possible resource for their child and siblings.

There May Be Situations Where Stem Cells from a Sibling Are Needed

While preserving your child’s own stem cells can be valuable, there are situations where stem cells from a sibling or another family member may be preferred. For example, if a child has a genetic condition, their own stem cells may carry the same genetic change. In these cases, doctors may look for stem cells from a healthy sibling or another suitable donor. This is one reason some families decide to store cord blood for more than one child.

Regenerative Medicine Is Exploring New Possibilities

Regenerative medicine focuses on repairing, replacing, or regenerating damaged cells, tissues, or organs. Because some cord blood stem cells have properties that may support tissue repair and cell development, researchers are studying their potential use in regenerative medicine. Clinical research is exploring how stem cells may help treat conditions such as heart disease, spinal cord injuries, cerebral palsy, autism, Alzheimer’s disease, hearing loss, and vision-related conditions. While many of these applications are still being studied, researchers continue to explore the future possibilities of stem cell-based therapies.

8) Cord Blood Stem Cells Are More Adaptable Than Other Sources

Cord blood stem cells have unique characteristics that make them valuable for transplantation. Compared with some other stem cell sources, such as bone marrow, cord blood stem cells are less likely to cause certain immune-related complications. They may also require less intensive matching compared with adult stem cell sources, making them an important option in many transplant situations.

These cord blood facts show why umbilical cord blood, once considered medical waste, has become an important resource in modern medicine. For expecting parents, understanding how cord blood is collected, stored, and used can help you make an informed decision about whether cord blood banking is the right choice for your family.
