About Cord Blood

What is cord blood?

Cord blood is the blood that remains in a baby’s umbilical cord and placenta immediately after the baby is born and the umbilical cord has been clamped and cut.

Your baby’s cord blood contains a diverse mixture of important cells, including stem cells. Cord blood is a particularly rich source of haematopoietic stem cells (HSCs), which have the ability to create and heal our organs, blood and the immune system. Because of their “youth”, stem cells from umbilical cord blood are among the most flexible and potent in the body.

How can cord blood be used?

Worldwide, cord blood has been used in over 40,000⁴² transplants in the treatment of over 80 conditions.⁴³ In Australia, over 500 cord blood units have been released to treat many conditions here and abroad.³³

Diseases treated by cord blood transfusion⁴⁴*

Cancer	Acute leukaemia Chronic leukaemia High-risk solid tumours Hodgkin and non-hodgkin lymphoma Myelodysplastic syndromes
Blood disorders	Aplastic anaemia Beta thalassaemia Diamond-blackfan anaemia Fanconi anaemia Sickle cell disease
Immune disorders	Chronic granulomatous disease Hystiocytic disorders Leukocyte adhesion deficiency Severe combined immunodeficiency diseases Wiskott-Aldrich syndrome
Metabolic disorders	Krabbe disease Hurler syndrome Metachromatic leukodystrophy Sanfilippo syndrome

Why is cord blood commonly used in treatments?

Collection is simple and non-invasive:

Collection and storage is simple and painless for both mother and baby
Once stored it is available immediately for treatment
There is no need to locate a compatible donor
No invasive procedures to harvest bone marrow

Cord blood medical advantages:

Cord blood stem cells are more potent than adult stem cells
Cord blood stem cells haven’t had exposure to environmental pollutants, viruses and chemicals that happen over time

Cord blood flexibility:

Greater flexibility in genetic matching - only a partial match between the donor and patient may be required
Reduced risk of graft vs host disease and lower incidence of viral transmissions

A perfect match:

Your baby’s umbilical cord stem cells are a perfect match for your child, and are more likely to be a match for siblings
The closer the match, the greater the likelihood of the body accepting the cells

New treatments being researched that anticipate using cord blood stem cells

In a growing number of advanced clinical trials, scientific research is evaluating how cord blood cells may provide new therapies for a broad array of diseases including autism,⁵ cerebral palsy,⁶ type 1 diabetes,⁷ and paediatric stroke.⁸

Probability of use

The probability of using stored cord blood is difficult to predict. Many factors impact the likelihood of use including the prevalence of disease, treatment options available, age and therapies that may be approved in the future.

It is important to note that estimates of use may vary considerably for these reasons. Today, based on currently approved therapies and ignoring the trials and research being undertaken, the chance of a child requiring stem cell therapy is 1 in 3,000.²

* Storing your baby's cord blood stem cells makes them available to potentially treat diseases like those listed above. For inherited genetic conditions, the child may not be able to use his or her own stem cells. In these cases, a matched sibling's stem cells may be an alternative.
