What is the Difference Between Cord Blood and Bone Marrow Stem Cells?
🆚 Go to Comparative Table 🆚Cord blood and bone marrow stem cells are both used in stem cell transplants, but they have some differences:
Cord blood stem cells:
- Derived from umbilical cord blood.
- Called Hematopoietic Stem Cells (HSCs).
- Primarily researched for blood and immune system disorders.
- Faster procurement compared to bone marrow donor.
- Immunologically naïve, making them more tolerant of tissue mismatches between donor and patient.
- Can be used for transplant in patients without a fully matched available donor.
Bone marrow stem cells:
- Derived from bone marrow.
- Transplanted from donor to recipient.
- Extracted from the breastbone, skull, hips, ribs, or spine.
- Invasive and slightly painful collection process.
- Potential risk of rejection and infection.
In summary, cord blood stem cells have some advantages over bone marrow stem cells, such as faster procurement, immunological naïveté, and the ability to be used in patients without a fully matched donor. However, both sources of stem cells are used in transplantation and have their own benefits and risks.
Comparative Table: Cord Blood vs Bone Marrow Stem Cells
Here is a table comparing the differences between cord blood and bone marrow stem cells:
Feature | Cord Blood Stem Cells | Bone Marrow Stem Cells |
---|---|---|
Source | Umbilical cord blood collected from a newborn after delivery | Bone marrow extracted from the donor's bones |
Collection | Non-invasive collection from the umbilical cord | Invasive extraction from bone marrow sites, such as breastbone, skull, hips, ribs, or spine |
Cell Division Kinetics | Different cell division kinetics compared to bone marrow stem cells | Similar cell division kinetics to cord blood stem cells, but different expression of CD34 and CD38 |
Immune System | Less mature antigens, lower risk for Graft-Versus-Host Disease | More mature antigens, higher risk for Graft-Versus-Host Disease |
Matching | Can be transplanted with only a partial human leukocyte antigen match | Requires a close human leukocyte antigen match |
Availability | Can be made available more quickly than bone marrow or peripheral stem cells | May take several months to find a matching donor |
Storage | Can be tested, frozen, and stored in a cord blood bank for future use | Must be collected, processed, and stored correctly to be usable |
Transplantation | Can be used to treat various oncologic, genetic, hematologic, and immunodeficiency disorders | Used to treat similar conditions, but may have limitations due to cell availability and matching requirements |
Cord blood stem cells have some advantages over bone marrow stem cells, such as being less invasive to collect, having different cell division kinetics, and being more widely available for transplantation. However, both types of stem cells can be used to treat various medical conditions.
