What is Stem Cell Preservation?
What are Stem Cells?
Stem cells are special cells in the body that can :
- Self-renew and multiply
- Develop into different cell types
- Help repair and regenerate damaged tissues
Umbilical cord blood is a rich source of hematopoietic stem cells, while cord tissue contains mesenchymal stem cells with regenerative potential.
Why is Stem Cell Preservation Important?
Stem cell preservation offers a potential biological resource for future medical use. Preserved stem cells may be used in the treatment of certain :
- Blood disorders
- Immune system disorders
- Bone marrow diseases
- Genetic conditions
- Certain cancers such as leukemia and lymphoma
Research is also ongoing in regenerative medicine for conditions affecting the heart, nerves, joints, and other organs.
How is Cord Blood Collected?
The collection process is simple, safe, and performed immediately after childbirth.
Step-by-Step Process
1. Delivery of the Baby
After the baby is delivered and the umbilical cord is clamped and cut, cord blood collection is performed.
2. Collection of Cord Blood
Blood remaining in the umbilical cord and placenta is collected into a sterile collection bag.
3. Cord Tissue Collection
In some cases, a small segment of umbilical cord tissue is also preserved.
4. Transportation and Storage
The collected sample is transported under controlled conditions to a specialized stem cell laboratory for processing and cryopreservation.
Advantages of Stem Cell Preservation
- Completely safe and painless procedure
- Non-invasive for both mother and baby
- Provides a potential future medical resource
- Readily available if needed in future treatments
- May benefit siblings or family members in selected situations
- Eliminates the need for donor search in some conditions
Types of Stem Cell Banking
Private Banking
Stem cells are stored exclusively for the child and family’s future use.
Public Banking
Stem cells are donated anonymously for public use and research purposes.
The choice depends on individual preferences, medical history, and availability of facilities.
Safety and Storage
Stem cells are preserved using advanced cryopreservation techniques at extremely low temperatures to maintain long-term viability and quality.
Specialized stem cell banks follow strict protocols for:
- Infection screening
- Sample processing
- Temperature monitoring
- Quality assurance
- Secure long-term storage
