What Conditions Can Cord Blood Stem Cells Treat?

Updated

Cord blood stem cells have an established use in rebuilding a child's immune system after cancer treatment, where they serve as an alternative to bone marrow transplants. Beyond that, research is exploring their potential for conditions like type 1 diabetes and brain injuries at birth. According to CordBank New Zealand, cord blood has been used for this purpose for the past 30 years, and newer therapies are still emerging.

Established Use: Rebuilding the Immune System After Cancer Treatment

The most well-documented application of cord blood stem cells is in restoring a child's immune system following cancer treatment. CordBank states that for the past 30 years, cord blood has been used as an alternative to bone marrow transplants for this purpose.

This matters because a bone marrow transplant requires finding a matching donor, which can be difficult and time-consuming. A child's own banked cord blood is already a perfect match and immediately available if needed.

CordBank shares the story of Frances, an Auckland child diagnosed at age four with stage four Neuroblastoma, a cancer of the nervous system. Her parents were told to take her home to die, but they used her banked cord blood to fight the disease. According to CordBank, she survived and is now well and healthy.

Emerging Therapies Under Research

CordBank highlights several areas where cord blood stem cells are being studied for new treatments:

  • Type 1 diabetes — listed as an emerging medical therapy for a child's own cord blood.
  • Brain injuries at birth — also cited as an emerging therapy.
  • Other uses — CordBank notes that many new applications are "rapidly emerging."

CordBank also describes the biological properties that make cord blood cells useful for this research:

Property What It Means
Potent Cord blood cells are described as the most powerful cells, undamaged by the aging process.
Flexible They can turn into other cell types, including heart, muscle, and nerve cells.
Powerful Used for 30 years to rebuild children's immune systems after cancer treatment.
Potential Emerging therapies include type 1 diabetes and brain injuries, with more uses being researched.

A Real-World Example: Brain Injury at Birth

CordBank shares the story of Daniel and Jillian, whose twin daughter Maia suffered oxygen deprivation at birth. The injury left her "disconnected" and developmentally delayed, and she failed to meet usual developmental milestones.

Because her stem cells had been banked at birth, they could be used to repair her brain injury. This illustrates how banked cord blood may become relevant for conditions that are not apparent until after birth.

What This Means for Decision-Making

If you are considering cord blood banking, the key question is whether the current and emerging uses are relevant to your family's situation. The established use — immune system rebuilding after cancer treatment — is well-documented. The emerging uses — type 1 diabetes, brain injuries, and others — are still under research, which means they may not yet be routine treatment options.

CordBank positions banking as a way to "future-proof" a child's health, noting that children today will live longer than ever. Whether that potential is worth the cost depends on your circumstances. CordBank provides pricing information on its website, so you can review the specific costs before deciding.

For families with a known family history of conditions treatable with cord blood, or those who want to preserve the option for emerging therapies, banking may be worth considering. For others, the decision comes down to how you weigh the established benefits against the still-developing research.
