Pediatric to Adult: The Growing Lifespan of Cord Blood Treatments

Cord blood, once primarily used for treating childhood illnesses, is now proving to be a long-term medical resource for individuals of all ages. Stored stem cells remain viable for decades, offering treatment options for over 80 conditions, including blood cancers, immune disorders, and emerging regenerative therapies.

Key points:

• Cord blood retains 89% viability after nearly 30 years of storage.
• FDA-approved treatments address both pediatric and adult conditions, such as leukemia, lymphoma, and metabolic disorders.
• New techniques, like stem cell expansion, make single units sufficient for adults.
• Clinical trials explore its use for strokes, autism, diabetes, and more.

Families can bank cord blood for future use, with upfront costs averaging $5,000 for lifetime storage. This investment provides potential benefits not just for the child but also for siblings and parents. Choosing a trusted provider with advanced preservation methods ensures the sample remains effective for decades, making it a critical part of long-term health planning.

What Are Cord Blood Stem Cells and How Do They Work

The Biology of Cord Blood Stem Cells

Cord blood stem cells are found in the blood left in the umbilical cord and placenta after birth. These cells are essential for regeneration and are less developed than adult stem cells. This immaturity makes them more flexible and lowers the risk of immune rejection when transplanted. Because of this, they are less likely to cause Graft-versus-Host Disease (GVHD), a serious condition where transplanted cells attack the recipient's body.

Cord blood contains two key types of stem cells. Hematopoietic Stem Cells (HSCs) are responsible for regenerating the blood and immune systems by forming red blood cells, white blood cells, and platelets. Mesenchymal Stem Cells (MSCs) can develop into tissues like bone, cartilage, and muscle. These cells contribute to healing in several ways: they can transform into specialized cells, regulate the immune system to reduce inflammation, and release growth factors that aid in tissue repair. Over 40,000 umbilical cord blood transplants have been performed globally to treat both cancerous and non-cancerous conditions, highlighting the versatility of these cells in medical treatments.

However, a single cord blood unit often contains fewer HSCs than a bone marrow donation, which can be a challenge for adult patients who may need two units for successful treatment. A breakthrough FDA-approved procedure using a nicotinamide modification has addressed this issue by increasing hematopoietic cell counts by 50 times, making treatments more accessible and effective.

How Freezing Preserves Stem Cells Over Time

Understanding cord blood banking benefits and how to preserve these cells is just as important as their biological properties. Cryopreservation, the process of freezing cells at extremely low temperatures, effectively stops cellular aging. After collection, the cord blood undergoes quality checks before being frozen, creating a ready-to-use product for future medical needs. Dr. Andromachi Scaradavou from Memorial Sloan Kettering Cancer Center explains:

Under proper banking conditions, cord blood stem cells retain their youthful properties.

Studies on long-term storage have confirmed this stability. Cord blood stored for as long as 29 years has shown that total nucleated cell (TNC) recovery and CD34+ cell viability remain virtually unchanged. CD34+ cells are especially critical because their ability to survive after thawing is closely tied to successful engraftment during transplantation. This means stem cells collected at birth can stay effective for treatments throughout a person’s life - from childhood to old age. Their durability ensures they remain a reliable therapeutic option for both pediatric and adult medical needs, making them an invaluable resource for long-term health care.

Cord Blood Treatments for Children

Childhood Diseases Treated with Cord Blood

Cord blood stem cells have shown impressive results in treating pediatric blood cancers, inherited metabolic disorders, and immune system deficiencies. Survival rates for children undergoing donor cord blood transplants are around 70-80%, making it a critical option for many families. Commonly treated conditions include acute lymphoblastic leukemia (ALL), acute myelogenous leukemia (AML), blood disorders like sickle cell disease (which affects 1 in 365 Black or African American births), and thalassemia major. Inherited metabolic disorders such as Hurler syndrome (MPS-IH), Krabbe disease, and Hunter syndrome (MPS-II), as well as immune deficiencies like severe combined immunodeficiency (SCID) and Wiskott-Aldrich syndrome, also benefit from cord blood treatments.

One of the key advantages of cord blood is its immediate availability and adaptability. Dr. Colleen Delany, Director of the Cord Blood Transplant Program at Fred Hutchinson Cancer Research Center, explains:

Cord blood is so immature it's more tolerant to be in a new environment. It enables nearly universal donor compatibility.

This flexibility allows for faster treatment timelines, which is crucial for aggressive childhood conditions. Families who bank their child’s cord blood at birth also gain an added advantage - there’s a 25% chance it will be a perfect genetic match for a sibling and a 50% chance of being a partial match. This can eliminate the need to search for unrelated donors, offering hope and convenience when time is critical.

Real Cases of Successful Pediatric Treatments

Real-life examples highlight how cord blood has transformed the lives of children facing severe illnesses.

In January 2025, three-year-old Tommy Bacon from Australia was diagnosed with juvenile myelomonocytic leukemia (JMML), a rare cancer affecting only 1-2 children per million annually. After two unrelated bone marrow donors withdrew, cord blood from Tommy’s baby sister Aria - banked at birth - turned out to be a perfect match. Just four months after the transplant, Tommy achieved remission. His mother Kylie reflected on their choice to bank cord blood:

If it can change a life in such a huge way, why would you not?

Five-year-old Gunner Lewis-Vale from Shropshire, UK, underwent a life-saving transplant in January 2024 for Hurler syndrome (MPS I). The umbilical cord blood, stored since 2008, restored enzyme production and prevented severe organ damage, changing the course of his life.

In May 2021, Eli Cola-Achille, a 10-year-old with sickle cell disease, received a transfusion of cord blood and bone marrow stem cells from his younger brother Gus. Treated at the Dana-Farber Cancer Institute, Eli experienced a dramatic improvement - reporting zero hospital visits and better blood counts a year later. His mother Nicole expressed her gratitude:

I'm so thankful for Americord and that Gus's cord blood is the reason his brother is so healthy today.

Nine-year-old Jenna Gibson, diagnosed with high-risk acute myeloid leukemia (AML) in 2015, found hope through a 6/6 matched cord blood transplant at the Fred Hutchinson Cancer Research Center. As an adopted child of Guatemalan descent, traditional bone marrow matches were unavailable. The transplant left her cancer-free for over two years, showing how cord blood can provide critical options for children from mixed or minority backgrounds who might otherwise struggle to find a match.

These stories underscore the life-saving potential of cord blood for children. While its immediate benefits are clear, ongoing advancements continue to explore how cord blood can serve as a medical resource well into adulthood.

Cord Blood Treatments for Teens and Adults

Adult Conditions Now Treated with Cord Blood

Cord blood stem cells aren’t just for kids - they’re making waves in adult treatments too, tackling blood cancers, neurological disorders, and cardiovascular conditions. With over 40,000 cord blood transplants performed globally, the possibilities keep expanding.

For adults battling leukemia (AML, ALL, CLL, CML), Hodgkin’s and Non-Hodgkin’s lymphoma, and multiple myeloma, cord blood offers a solid alternative to bone marrow, especially when finding a donor is tough. One innovative approach - double cord blood transplantation - uses two units to meet the higher cell count needed for larger adult bodies, solving the issue of limited cell numbers.

In April 2023, the FDA approved a game-changing procedure that multiplies hematopoietic stem cells by 50 times using nicotinamide modification. This breakthrough makes single-unit transplants a practical option for larger patients, especially those with hematopoietic cancers, and is available for individuals aged 12 and older.

Cord blood’s potential goes beyond cancer. Clinical trials are exploring treatments for Alzheimer’s disease, Parkinson’s disease, ALS, and recovery from strokes. Back in June 2019, Dr. Joanne Kurtzberg from Duke University led a Phase I safety study (CoBIS) involving 10 stroke patients who received non-HLA matched cord blood infusions. Over a year, all participants showed improvement without experiencing Graft-versus-Host Disease (GvHD).

Even in cardiovascular health, cord blood is being studied for conditions like heart attack recovery, heart failure, and cardiomyopathy. Research is also looking at its role in managing Type 1 and Type 2 diabetes, liver cirrhosis, and kidney failure. Dr. Kurtzberg, a leader in this field, shared her perspective:

The use of cord blood cells will emerge as one of the major great advances in novel therapeutics in medicine over the next decade.

Currently, cord blood stem cells are used to treat or manage around 80 diseases, with new applications being explored all the time. These developments are opening doors to treatments that could last a lifetime.

Why Cord Blood Stays Useful for Decades

Cord blood’s benefits don’t fade with time. It remains a perfect genetic match for the donor throughout their life, making autologous transplants (using your own cells) immune to rejection. Unlike bone marrow transplants, it doesn’t require the HLA matching and stem cell transplants that can complicate donor searches.

Studies confirm that cord blood stored for up to 17 years retains its effectiveness, with no decline in potency or function. Thanks to the freezing process, these cells stay ready to differentiate into various types, ensuring they remain viable for decades.

Another major advantage? Cord blood’s immature immune cells reduce the likelihood of Graft-versus-Host Disease, making it effective even with less stringent matching. This is a game-changer for adults who might otherwise struggle to find a perfect donor match. With its long-term viability and adaptability, cord blood continues to be a cornerstone of regenerative medicine, offering hope for treating conditions at any stage of life.

Approved and Experimental Cord Blood Therapies

FDA-Approved Treatments by Age Group

FDA-approved cord blood therapies have expanded to address a wide range of conditions, tailored to specific age groups. These treatments are effective against over 80 conditions, including blood cancers, metabolic disorders, and immune deficiencies, for both children and adults.

For children, approved applications focus on diseases such as juvenile myelomonocytic leukemia (JMML), neuroblastoma, and inherited metabolic disorders like Krabbe Disease and Hurler Syndrome. Adults benefit from treatments for conditions like acute myeloid leukemia (AML), chronic myeloid leukemia (CML), and various lymphomas. One notable example is a Phase 2 trial conducted at Ruijin Hospital in Shanghai between January 2015 and February 2022. This study involved 51 AML patients aged 60–75 who received cord blood infusions as an additional therapy. After a median follow-up of 27.3 months, the two-year overall survival rate was 76.9%, a marked improvement over standard chemotherapy outcomes for this demographic.

Both autologous (using the patient’s own cells) and allogeneic (using donor cells) transplants are approved. Survival rates underscore the effectiveness of these treatments: children undergoing donor cord blood transplantation show overall survival rates of 70% to 80%, while high-risk leukemia patients in their first complete remission have a five-year survival rate of 59%. These successes pave the way for emerging regenerative therapies currently in development.

Clinical Research in Regenerative Medicine

Cord blood research is moving beyond traditional uses, focusing on regenerative medicine aimed at repairing tissues and organs. This new frontier holds promise for neurological, cardiovascular, and orthopedic conditions, offering hope for both age-related and developmental disorders.

Neurological applications are a major focus. For children, clinical trials are targeting autism spectrum disorder (ASD), cerebral palsy, and complications from premature birth. A compelling example is the case of five-year-old Olivia Fohs, who, in January 2019, underwent a 15-minute infusion of her own cord blood as part of an autism clinical trial. Following the treatment, her diagnosis improved from ASD level 2 (mild to moderate) to level 1. For adults, studies are investigating potential treatments for Alzheimer’s disease, Parkinson’s disease, ALS, traumatic brain injuries, and spinal cord injuries.

Cardiovascular and autoimmune conditions are also under active investigation. Researchers are exploring the use of cord blood in treating heart failure, acute myocardial infarction, and cardiomyopathy. Autoimmune disease trials include conditions such as Type 1 and Type 2 diabetes, lupus, rheumatoid arthritis, Crohn’s disease, and multiple sclerosis. In February 2022, a groundbreaking case highlighted the potential of cord blood: a mixed-race woman became the first woman - and only the third person ever - reported to be cured of HIV following a stem cell transplant using umbilical cord blood. This approach was chosen due to cord blood’s ability to match patients from diverse racial backgrounds more easily.

Orthopedic research is also advancing, with studies exploring treatments for osteoarthritis, cartilage injuries, spinal fusion surgery, and non-union fractures. Dr. Paul R. Sanberg from the University of South Florida’s Department of Neurosurgery and Brain Repair explains:

cord blood cells are currently approved for reconstitution of bone marrow following myeloablation in both young and old patients with blood cancers, but the experimental frontier is rapidly expanding.

How to Choose a Cord Blood Bank

What to Look for in a Cord Blood Bank

Picking the right cord blood bank is a big decision, and there are a few critical factors to weigh to ensure your child’s stem cells are preserved properly for decades.

Start by checking for FDA registration and compliance with regulations for Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/Ps). This guarantees the bank follows strict procedures for donor screening, disease testing, and handling, all of which are essential for keeping the sample intact and usable.

Accreditation is another key factor. Look for banks accredited by the AABB (American Association of Blood Banks) or FACT (Foundation for the Accreditation of Cellular Therapy). These accreditations mean the bank’s processes, from collection to storage, are regularly audited. This reduces risks like contamination or errors in labeling, ensuring the sample remains viable and ready for future use. Accredited banks also maintain detailed records and follow strict protocols, which gives families peace of mind about their investment.

Long-term storage capabilities are equally important. Properly cryopreserved cord blood can stay viable for decades - research from the New York Blood Center shows samples stored for over 23 years remained high quality. Similarly, a study in Düsseldorf found that cord blood units stored for 29 years still had over 88% cell viability. Since private storage can cost several thousand dollars, it’s smart to ask what happens if the bank merges, shuts down, or is acquired. Reliable banks will have contingency plans to transfer samples to another accredited facility seamlessly.

When comparing banks, make sure they offer clear pricing. Ask for a detailed breakdown of costs, including fees for collection kits, processing, and storage. Initial storage and lifetime plans can exceed $5,000, so it’s important to confirm whether additional fees apply for retrieval, shipping, or testing. Also, check their refund policy in case the sample collected isn’t usable.

Finally, processing quality is critical. The number of viable stem cells preserved directly impacts the sample’s future use. Ask about the bank’s processing methods, the minimum cell counts they require, and the tests they perform before freezing. Controlled-rate freezing and storage in liquid nitrogen are the gold standard. Look for facilities with CLIA-certified labs that follow Good Manufacturing Practice (GMP) standards, as these are trusted by transplant centers across the country.

Why Americord Registry Stands Out

Americord Registry sets itself apart by focusing on superior quality and innovative approaches to cord blood banking.

One standout feature is their CryoMaxx™ Processing, a proprietary method designed to recover more stem cells, including higher counts of total nucleated cells (TNCs) and CD34+ cells, compared to standard processing. This matters because transplant success often depends on having enough viable cells. By preserving more cells, Americord increases the chances that a single collection will be sufficient for a wider range of future treatments, even as the child grows into adulthood.

Americord also offers lifetime storage, keeping samples preserved for up to 78 years. This aligns with research showing that cord blood remains viable for decades and anticipates the growing use of stem cells in therapies for adults and seniors. Their storage facilities are equipped with redundant power systems, continuous monitoring, and strict chain-of-custody protocols, ensuring that samples remain secure and transplant-ready.

In addition to cord blood, Americord provides comprehensive banking options, including cord tissue, placental tissue, and exosomes. These additional sources are being explored in numerous clinical trials for regenerative medicine, giving families more potential treatment options as science advances. Americord also prioritizes personalized customer service, offering 24/7 clinical support for labor and delivery teams, pre-labeled collection kits, and same-day courier services with temperature-controlled shipping to protect cell viability.

For families dealing with specific medical conditions, the Americord Cares program offers free banking. A compelling example of their impact is five-year-old Olivia Fohs, who received an infusion of her own cord blood in 2019 as part of an autism clinical trial. Her parents had banked her cord blood with Americord in 2013, and after the treatment, her autism severity improved from level 2 to level 1. This story highlights the potential benefits of choosing a provider with advanced processing methods and a commitment to long-term storage.

Conclusion

Cord blood banking offers a meaningful way to invest in your family's health, providing a resource that’s useful from birth and throughout life.
