Why Bank Stem Cells

Benefits of saving cord blood

Here are some of the many reasons why you should store your baby’s cord blood stem cells.

guaranteed match for autologous transplants.

Autologous stem cell transplants are transplants in which the same person is both the donor and the recipient of the stem cells. The cord blood you are saving for your baby now could be used as a medical resource in the future. Unlike traditional bone marrow stem cell transplants, cord blood does not need to be a perfect match. Every year, 40–60% of patients in Singapore who need a stem cell transplant can't find a good match in public cord blood banks or among bone marrow donors.1 The odds of finding a match within the same racial group are only 1 in 20,000.2

A readily available supply of stored Haematopoietic Stem Cells.

In the event that stem cells are needed for a transplant in an already time-critical situation, having your child’s cord blood stored compares favourably to having to conduct a costly and time-consuming national or international search. Procuring a cord blood sample can cost up to $90,000 in Singapore, assuming a match is found.3

Lower risk of Graft vs. Host Disease (GvHD) in autologous transplants.

When using stem cells from cord blood, the risk of Graft vs. Host Disease (GvHD) is lower for autologous transplants, where the donor and recipient are the same person, as compared to transplants from unrelated donors.

GvHD is a condition where the transplanted tissue cells (the graft) see the patient’s own tissue (the host) as foreign and attacks them.

Up to 75% chance of matching genetically between siblings.4

Umbilical cord blood from a sibling offers a lifetime of protection for the family as the stored cord blood offers a higher potential for genetic matches. Many families have benefited from using sibling stem cells for treatment.

Umbilical cord blood stem cells are younger and more primitive.

Umbilical cord stem cells can grow healthy blood cells faster than other types of stem cells obtained from other sources, such as bone marrow and peripheral blood.5,6 They are also more tolerant to HLA* mismatches.7

*Human leukocyte antigens, or HLAs, are proteins that help the immune system tell the difference between the body's own cells and foreign substances that could be harmful.

Cord blood collection is safe and painless for both mother and baby.

Cord blood collection is a simple task that is taken care of by your own OBGYN. The process of cord blood collection does not affect the birthing process in any way and can be done for both natural and C-section births.

Treatable Diseases & Research

Over 80 diseases 1 potentially treatable with cord blood stem cells

Stem cells are now at the forefront of one of the most fascinating and revolutionary fields in medicine. Blood-forming stem cells, also called Haematopoietic Stem Cells (HSCs), can be found in your baby's cord blood. These cells have the potential to treat more than 80 diseases 1, including some types of cancer like leukaemia, neuroblastoma, and lymphoma.

During a stem cell transplant, stem cells are infused into the patient’s bloodstream, where they start to heal damaged cells and tissues. The patient’s blood and immune system are regenerated after the stem cells successfully engraft.

DID YOU KNOW?

Haematopoietic Stem Cells (HSCs) can potentially be used to treat over 80 diseases1.

List of diseases potentially treatable with cord blood stem cells

Cord Blood

What are cord blood stem cells?

The umbilical cord is a tube-like structure connecting the foetus to the placenta in mother's womb, providing nutrients and removing waste from baby. Cord blood, which is also called "placental blood", is blood that remains in the umbilical cord and placenta following the birth of a baby and after the umbilical cord is cut after delivery. Through the science of cord blood banking, cord blood can help nurture life, long after a baby's birth and provide a source of stem cells should the need ever arise for a stem cell transplant. This is because cord blood is a rich source of stem cells known as haematopoietic stem cells (HSCs). These HSCs are primarily responsible for replenishing blood and regenerating the immune system.

Cord blood stem cell transplants are used in the following ways:

  • Replace and regenerate damaged or diseased bone marrow
  • Treatment for blood cancers
  • Correct genetic defects (sibling/allogeneic transplantation)
  • Potential for cellular therapy and regenerative medicine

They have the unique ability to differentiate into various cell types found in blood as depicted in the diagram below:

Red Blood Cells

Carry oxygen to all cells in the body

White Blood Cells

Fight infection

Platelets

Assist blood clotting in the event of injury



Why Save Cord Blood Stem Cells

  • A guaranteed match for autologous transplants (where the donor and recipient are the same individual).

    Autologous stem cell transplants refer to transplants where the donor and recipient of the stem cells are the same individual. The cord blood that you are storing for your baby today is a potential medical resource for the future, and does not require stringent matching as opposed to conventional bone marrow stem cell transplants. About 70% of patients who need a transplant are unable to find a suitable match within the family1.
  • A Readily Available Supply of Stored Haematopoietic Stem Cells

    In the event of an already time-critical situation where stem cells are required for a transplant, having your child’s cord blood stored compares well to having to do a national or international search which is both costly and time-consuming. The cost of procuring a cord blood sample in Singapore can cost up to $75,0002, and that is, if a match is found.
  • Lower risk of Graft vs. Host Disease (GvHD) for autologous transplants

    Graft vs. Host Disease refers to a common complication where the transplanted tissue attacks the patient's own tissue. This disease will usually occur in transplants when the donor and recipient are different.
  • Ease of collection, which is pain-free and risk-free to both mother and child.

    Cord blood collection is a relatively easy task, which is handled by your own delivering doctor (OBGYN). This process does not affect the birthing process in any way and can be done on both natural and c-section births.
  • Umbilical cord blood stem cells are younger and more primitive

    In comparison to other types of stem cells, e.g bone marrow and peripheral blood stem cells, there is a notably higher rate of engraftment. This means the cells are faster in growing and making healthy blood stem cells and are more tolerant to tissue mismatches.
  • 1 in 217 chances of using stem cells for treatment in a lifetime

    Statistics have shown that 1 in every 217 persons may need stem cells for treatment in their lifetime3. Your baby’s cord blood contains a rich source of such stem cells. Since 1988, doctors have used cord blood stem cells to treat more than 30,000 patients4 suffering from diseases such as certain cancers like leukaemia, blood disorders as well as those in clinical trials
