Cord blood banking is the process of collecting and storing the blood from the umbilical cord and placenta after a baby is born. This blood is rich in stem cells, which have the potential to develop into various types of cells in the body. Cord blood banking can be categorized into two main types: public cord blood banking and private cord blood banking.
Public Cord Blood Banking:
Donation: In public cord blood banking, parents donate their baby's cord blood to a public bank. This donated cord blood is then made available to anyone in need of a stem cell transplant.
Free of charge: Public cord blood banking is usually free for donors. The collected units are listed on national or international registries, and they become part of a global resource for patients in need of a stem cell transplant.
Private Cord Blood Banking:
Storage for Personal Use: In private cord blood banking, parents pay to store their baby's cord blood for potential future use by their family.
Reserved for Family Use: The stored cord blood is reserved exclusively for the family's use, and it is not made available to the public.
Here are some key points to consider when deciding whether to bank cord blood privately or donate it to a public bank:
Cost: Private cord blood banking typically involves upfront fees and ongoing storage costs, while public cord blood banking is usually free for donors.
Likelihood of Use: The chances of using privately stored cord blood are relatively low, and many families never use the stored units. Publicly donated cord blood, on the other hand, may help others in need.
Availability: Public cord blood banks provide access to a larger and more diverse pool of stem cell units, which can be important for individuals from various ethnic backgrounds in need of a transplant.
Ethical Considerations: Some argue that donating cord blood to a public bank is a way to contribute to the greater good and help individuals who might not have access to a matched stem cell donor.
What is cord blood banking?
Cord blood banking involves the collection and storage of your baby's umbilical cord blood following delivery. This blood remains in the umbilical cord after it's cut, a process that occurs shortly after your baby is born. The umbilical cord, which links your baby to the placenta, is essential for supplying nutrients and oxygen to the developing fetus within your uterus.
The richness of stem cells in umbilical cord blood is noteworthy. Stem cells play a crucial role in treating numerous life-threatening diseases. While most healthy individuals can generate sufficient stem cells, some, afflicted by severe medical conditions or diseases, struggle to produce an ample supply of healthy stem cells. For these individuals, cord blood stem cells can be a lifesaving resource. Cord blood banks are established to collect and store these valuable stem cells, which healthcare providers may utilize for transplants in individuals with illnesses or for advancing medical research.
Cord blood banking is a voluntary choice. Some individuals opt to collect and store their baby's cord blood, while others choose not to. If you decide against donating or storing your baby's cord blood, it is typically discarded along with the placenta. Information about cord blood banking is commonly provided by your healthcare provider during prenatal visits.
What is cord blood?
Cord blood refers to the blood that remains in your baby's umbilical cord following childbirth. Resembling ordinary blood, it comprises red and white blood cells, platelets, and plasma. Notably, it contains a distinct type of stem cell, akin to those found in bone marrow, known for bolstering the immune system. The uniqueness of these cells lies in their capacity to mature into various blood cell types, rendering them highly valuable.
The versatility of stem cells extends to their role in treating various diseases, including leukemia, genetic disorders, immune system ailments, and more. Researchers have discovered that cord blood demonstrates effectiveness in treating as many as 80 different diseases.
What is cord blood banking used for?
Cord blood is rich in potentially life-saving stem cells, which can be a valuable resource for individuals in need of stem cell transplants. When transplanted into these individuals, the stem cells play a crucial role in generating new, healthy cells. Stem cell transplants are particularly beneficial for individuals facing various health challenges, including:
Cancers such as leukemia and lymphoma.
Bone marrow diseases necessitating a transplant.
Anemia, including conditions like sickle cell disease.
Certain disorders affecting the immune system.
Researchers are actively exploring the potential of cord blood in treating additional life-threatening conditions, such as Parkinson's disease and diabetes. Ongoing studies aim to uncover the broader therapeutic applications of cord blood in the realm of medical treatments.
How do they find a match for stem cells from cord blood?
Finding a suitable match for stem cells from cord blood involves a process similar to matching for bone marrow or peripheral blood stem cell transplantation. The goal is to find the best possible match between the donor's (cord blood in this case) and the recipient's tissue types. The primary factors considered for matching include human leukocyte antigen (HLA) compatibility.
Here's how the matching process generally works:
Human Leukocyte Antigen (HLA) Typing:
HLA is a system of proteins found on the surface of cells. These proteins play a crucial role in immune system regulation. To find a suitable match, both the donor's cord blood and the recipient's tissues are tested for HLA compatibility. The more closely the HLA types match, the higher the chance of a successful transplant.
Ideally, a perfect HLA match is sought, especially for conditions like leukemia and other blood disorders where a higher level of matching is crucial. However, not all patients have a fully matched donor available. In such cases, doctors may consider a partially matched or mismatched transplant, but this increases the risk of complications.
Cord Blood Banks:
Cord blood banks maintain detailed records of the HLA types of stored cord blood units. When a patient needs a stem cell transplant, the medical team searches the registry to find a suitable cord blood unit with a matching or closely matching HLA profile.
Public cord blood banks often contribute to global registries, allowing healthcare providers to search for potential matches beyond their local bank. This is especially important for individuals from diverse ethnic backgrounds, as finding a match can be more challenging due to the genetic diversity within different populations.
Parental or Sibling Matches:
In some cases, a patient's cord blood may be stored for their own potential use, providing a perfect HLA match. Additionally, cord blood from siblings or parents may also be a suitable match.
It's important to note that the success of a stem cell transplant depends not only on HLA matching but also on other factors, such as the patient's overall health, the type of condition being treated, and the stage of the disease. In cases where a fully matched donor is not available, transplant specialists carefully weigh the risks and benefits to determine the most appropriate course of action.
What are the types of umbilical cord blood banking I can do?
There are two main types of umbilical cord blood banking: public cord blood banking and private cord blood banking. Each type serves different purposes and has distinct characteristics:
Public Cord Blood Banking:
Donation to a Public Bank: In public cord blood banking, parents choose to donate their baby's cord blood to a public cord blood bank. The donated cord blood becomes part of a public registry and is made available to anyone in need of a stem cell transplant.
No Cost to the Donor: Public cord blood banking is typically free for donors. The collected units are used for patients who require a stem cell transplant, and the anonymity of the donation is maintained.
Public banking is a altruistic choice where you contribute to a global resource, potentially helping individuals worldwide.
The donated cord blood may be used for any patient in need, not just for your family.
Private Cord Blood Banking:
Storage for Personal Use: In private cord blood banking, parents pay to store their baby's cord blood for potential future use by their family. The stored cord blood is reserved exclusively for the family's use.
Cost Involved: Private cord blood banking involves upfront fees for collection, processing, and ongoing storage. Families are essentially paying for the exclusive access to the stored cord blood.
Private banking provides a personalized source of stem cells for your family, should there be a need for a stem cell transplant.
The stored cord blood is not available for public use; it is exclusively reserved for your family.
Factors to Consider:
Medical History: Consider your family's medical history and whether there is a known risk of diseases that could be treated with cord blood stem cells.
Cost: Private cord blood banking involves fees, so consider whether the cost is manageable for your family.
Likelihood of Use: The likelihood of using stored cord blood is relatively low. Evaluate the potential benefits against the cost.
Altruistic vs. Personal Use: Decide whether you want to make a contribution to the public good (public banking) or prioritize a personalized resource for your family (private banking).
It's essential to research and make an informed decision based on your individual preferences, financial considerations, and beliefs about the use of cord blood. Your healthcare provider can provide information and guidance to help you make the choice that aligns with your family's needs.
When do I need to decide about cord blood banking?
The decision about cord blood banking ideally needs to be made before the birth of your baby. It's typically recommended to think about cord blood banking during the later stages of pregnancy, ideally by the beginning of the third trimester. This timeframe allows you to research your options, gather information, and make an informed decision that aligns with your preferences and circumstances.
Here are a few key considerations to keep in mind:
Research and Education: Take the time to learn about cord blood banking, including the differences between public and private banking, the potential benefits, costs involved, and any ethical considerations. You can discuss this with your healthcare provider and consider attending informational sessions or speaking with representatives from cord blood banks.
Decision-Making Process: Discuss cord blood banking with your partner and other family members involved in the decision-making process. Consider factors such as your family's medical history, the likelihood of needing cord blood stem cells in the future, and your financial situation.
Preparation: If you decide to proceed with cord blood banking, make arrangements with a cord blood bank well in advance of your due date. This may involve completing paperwork, scheduling the collection process, and understanding the logistics of storing the cord blood.
Communication with Healthcare Provider: Inform your healthcare provider of your decision regarding cord blood banking. They can provide guidance, answer any questions you may have, and ensure that the necessary arrangements are made during labor and delivery.
By making a decision about cord blood banking before your baby's birth, you can ensure that everything is in place for a smooth and timely collection process. However, it's never too late to inquire about cord blood banking options, even if you're approaching your due date. Some cord blood banks offer expedited services for last-minute arrangements, though it's always best to plan ahead when possible.
How is cord blood collected?
Cord blood collection is a straightforward and non-invasive procedure that occurs after the birth of the baby. Here's an overview of the cord blood collection process:
After Birth: Cord blood collection takes place immediately after the baby is born and the umbilical cord is clamped and cut.
Sterile Collection Kit: The healthcare provider uses a sterile collection kit, which includes a special bag and needle, to collect the cord blood. The collection kit is specifically designed for this purpose and is provided by the chosen cord blood bank.
Insertion of Needle: The healthcare provider inserts a needle into the umbilical vein, which is part of the umbilical cord. This is done in a way that poses no risk or discomfort to the baby or the mother.
Draining Blood into Collection Bag: The blood flows from the umbilical cord into the collection bag by gravity. The bag contains an anticoagulant to prevent the blood from clotting during transportation and storage.
Closure of the Collection Process: Once an adequate amount of cord blood is collected, the needle is removed, and the collection bag is sealed. The entire process is quick and typically does not interfere with the birthing experience.
Labeling and Transport: The collected cord blood unit is labeled with specific information, including the mother's and baby's details, and is then transported to the cord blood bank for processing and storage.
How is cord blood stored?
Cord blood is stored through a process known as cryopreservation, which involves freezing the collected cord blood at very low temperatures to preserve the viability of the contained stem cells for an extended period. Here is an overview of how cord blood is stored:
Processing: After collection, the cord blood is transported to the cord blood bank where it undergoes processing. This typically involves separating and concentrating the stem cells from the other components of the blood, such as red blood cells and plasma.
Testing: The cord blood may be tested for various parameters, including the number of stem cells, cell viability, and the absence of infectious diseases. This ensures that the stored cord blood meets quality standards.
Cryoprotectant Addition: To protect the cells during freezing and thawing, a cryoprotectant (a substance that prevents ice formation) is often added to the cord blood. This helps minimize damage to the cells caused by freezing and ensures a better chance of cell survival.
Freezing: The processed cord blood is then placed in special containers or bags designed for cryopreservation. These containers are gradually frozen to extremely low temperatures, often around -196 degrees Celsius (-321 degrees Fahrenheit), using controlled-rate freezers or liquid nitrogen.
Storage: Once frozen, the cord blood is transferred to long-term storage in cryogenic storage tanks filled with liquid nitrogen. These tanks are specially designed to maintain low temperatures and prevent temperature fluctuations. The cord blood remains in this state until it is needed for potential medical treatments.
Is cord blood banking free?
Public cord blood banking is typically free for the donors. When parents choose to donate their baby's cord blood to a public cord blood bank, they are contributing to a global resource that is made available to anyone in need of a stem cell transplant. Public cord blood banks may cover the costs associated with collection, processing, and storage.
On the other hand, private cord blood banking involves a fee. Families who choose private cord blood banking pay for the collection, processing, and long-term storage of their baby's cord blood. Private cord blood banking is a service provided by private companies, and the cost can vary depending on the company and the specific services offered.
Risks / Benefits
Why should I bank umbilical cord blood?
The decision to bank umbilical cord blood is a personal one and depends on various factors. Here are some potential reasons why individuals choose to bank umbilical cord blood:

Timing of Decision:
Decision Before Birth: In both public and private cord blood banking, the decision to donate or bank cord blood must be made before the birth of the baby. Planning ahead is crucial to ensure that the necessary arrangements can be made.
Recovery and Outlook
Is my delivery affected by donating my baby's cord blood?
No, donating your baby's cord blood typically does not affect the delivery process. The cord blood collection occurs after the baby is born and the umbilical cord is clamped and cut, which are routine procedures during childbirth. The collection itself is a quick and non-invasive process that does not interfere with the delivery or postpartum care.
Here are some key points to consider:
Timing of Collection: Cord blood collection takes place after the baby is born, and the healthcare provider has clamped the umbilical cord. It does not impact the timing or progression of labor and delivery.
Non-Invasive Procedure: The collection is a simple and non-invasive procedure that involves using a sterile collection kit to collect blood from the umbilical cord. This process usually takes only a few minutes and is performed by healthcare professionals trained in the procedure.
No Pain or Discomfort for the Baby: The baby does not experience any pain or discomfort during the cord blood collection. The collection is done in a way that is safe for both the baby and the mother.
No Impact on Postpartum Care: After the cord blood is collected, the healthcare team proceeds with routine postpartum care for both the mother and the baby. There is no additional recovery time or special care required due to the cord blood donation.
