In recent years cord blood banking has become increasingly popular amongst expectant parents but what exactly is cord blood banking and why should you consider it for your family?  Cells4Life, the UK’s leading umbilical cord blood stem cell bank, answer their most frequently asked questions.

What is cord blood?

Cord blood is the blood that remains in the placenta and umbilical cord after a baby is born and the umbilical cord is cut. This blood is rich in stem cells, specifically hematopoietic stem cells, which have the potential to develop into various types of blood cells, including red blood cells, white blood cells, and platelets. Hematopoietic stem cells are crucial for the production of blood in the body and play a vital role in the immune system.  

Why should I save my baby’s umbilical cord blood?

Cord blood is typically collected immediately after a baby is born and can be stored for future medical use. Collecting cord blood is non-invasive and painless for both the baby and the mother. The collected cord blood is processed, tested, and cryogenically frozen for long-term storage.

Should your baby ever need stem cell therapy, their cord blood is a 100% match[1]. In addition, should a family member need stem cell therapy, banking your baby’s cord blood could increase their chances of a match – for example, a sibling has a 40-60% chance of being a match.

Cord blood can be used in medical treatments to replace damaged or diseased blood and immune system cells in conditions such as leukaemia, lymphoma, and certain auto-immune disorders. These stem cells can help regenerate healthy blood cells and rebuild the immune system after chemotherapy or radiation treatments. Today, umbilical cord blood is used as an approved treatment for over 80 illnesses[2].

In addition to the treatments available today, there is promising research with stem cells in regenerative medicine, which one day could help grow new organs or possibly treat conditions such as Parkinson’s Disease.

Frozen cord blood can be stored indefinitely and could be used well into a donor’s old age; who knows what medical advancements have been realised in that time.

There is only one chance to store your baby’s cord blood – at birth.

Is cord blood banking compatible with my birth plan?

Cord blood banking is compatible with the following birth choices:

  • “Natural” birth
  • Caesarean birth
  • Multiple Birth
  • Home Birth
  • NHS hospital birth
  • Private hospital birth
  • Delayed cord clamping

Many believe delayed cord clamping and umbilical cord blood banking are incompatible. This is not the case. Cells4Life can yield up to 3 times more stem cells thanks to their exclusive processing technology, which has been peer-reviewed[3]. More cells mean more options and more therapies.

Should I store privately or donate?

That is a personal choice. However, most hospitals in the UK don’t have the facility to accept cord blood donations, illustrated by the fact that more than 65,000 litres of cord blood are discarded each year in the UK[4]. It will only be used for recognised therapies; anyone who is a match could use it if needed, or for research.  You can donate cord blood at the following hospitals:

For Anthony Nolan:

King’s College Hospital, London

Saint Mary’s Hospital, Manchester

Saint Mary’s Hospital, Wythenshawe (Manchester)

Leicester Royal Infirmary

Leicester General Hospital


University College Hospital

Luton and Dunstable Hospital

St George’s Hospital

For Cells4Life  Foundation:

Epsom Hospital

St Helier Hospital

When you store your baby’s cord blood in a private family bank, it can be used both for recognised stem cell therapies and clinical trials. The sample can only be used with your child’s or yourself’s expressed consent and will not be made available to the general public. Family banking ensures that your baby has their perfect match ready and waiting should it be needed.

How do I organise private family cord blood banking?
