About Cord Blood and Umbilical Cord
Cord blood can only be collected within a few minutes after birth, making it a precious resource for the baby.
The collection process is completely safe and painless for both the mother and the baby.
Both sources contain a large number of stem cells.
A wide range of applications is progressing in the field of regenerative medicine.
Since each source contains different types of stem cells, storing both expands future treatment options.
What are Stem Cells?
Stem cells are the foundation of various types of tissues in the body. They have the ability to produce blood, differentiate into nerve cells, bones, muscles, and other types of cells. Since they can reduce inflammation in damaged areas and aid in tissue repair, they are expected to be applied in various treatments.
What is Cord Blood?
The umbilical cord is the lifeline connecting baby and mother; and the blood flowing inside the umbilical cord is cord blood, which is a rich source of multi-potent cells called stem cells. For instance, hematopoietic stem cells have a great ability to form cellular elements of blood, such as red blood cells (erythrocytes), white blood cells (leukocytes) and platelets (thrombocytes) – therefore, these cells are useful in treating various refractory blood diseases,such as leukemia and aplastic anemia.
Indeed, as cord blood is known to contain stem cells that have the potential to transform into a diverse range of varied cells, such as cells with the potential to aid repair of damage to the central nerves and autoimmunity as well as ischemic injury, the medical field is showing a surge of interest in cord blood in recent years, which is raising expectations for future applications in regenerative medicine and cell therapies that are at the clinical trial and research stages right now.
Potential of Umbilical Cord Blood
Cerebral Palsy
In Japan, research is being conducted into the administration of umbilical cord blood from babies or siblings to treat cerebral palsy. Clinical studies overseas have reported that administration improves motor function and neural circuits.
Autism Spectrum Disorder
It is expected that administration of umbilical cord blood may improve communication skills and social adaptability.
A clinical trial to administer a child's own umbilical cord blood has begun at Osaka Municipal University,
and participants will be recruited in the future.
What is Umbilical Cord?
The umbilical cord connects mother and baby. In recent years, it has been discovered that the umbilical cord contains a large number of mesenchymal
stem cells, which are widely studied in the field of regenerative medicine.
Mesenchymal stem cells have an ability to move on to areas of inflammation in
the body to soothe inflammation and repair damaged tissue.
StemCell Institute's umbilical cord storage service enables
the umbilical cord to be frozen and preserved alive.
By freezing and storing the umbilical cord at the time of delivery,
it may make it possible to use it for medical and other purposes for
your child and your family.
Potential of Umbilical Cord
Family Supernatant
Stem cell culture supernatant containing exosomes and cytokines can be produced from stored umbilical cord and used by family members.
Various regenerative medical care
Basic research on regenerative treatments of meniscus injuries and cleft palate is currently being conducted in Japan. Future applications in various fields of regenerative medicine are highly anticipated.
【Guide to cord blood transfusion treatment using EAP】
What is EAP (Expanded Access Protocol)?
The Expanded Access Protocol (EAP) is a program that enables patients to receive umbilical cord blood infusion using methods equivalent to those validated in clinical research.
At Duke University in the United States, this program provides umbilical cord blood infusion to patients up to 26 years old diagnosed with cerebral palsy, hypoxic-ischemic encephalopathy, and other brain disorders. To date, more than 500 patients from around the world have traveled to Duke University to receive treatment under this program.
Among those storing their cord blood with the Stem Cell Institute, 13 individuals have undergone umbilical cord blood infusion at Duke University as of October 2024.
For further details, please refer to National Library of Medicine
Disclaimer: The EAP is an independent program administered by Duke University and is not affiliated with our services. We bear no responsibility for the registration process or participation in this program.
