Stem cells have been the subject of numerous scientific studies and it is one of the most fascinating topics in the medical world. There are two main types of stem cells: HSC and MSC stem cells. Understanding the difference between the two is essential to help families make informed decisions about stem cell banking.
Hematopoietic Stem Cells (HSCs)
HSCs are the stem cells responsible for producing blood cells. They are found in the bone marrow, peripheral blood, and cord blood. HSCs can differentiate into red blood cells, white blood cells, and platelets. The blood cells they produce play a crucial role in the body’s immune system and help to prevent infection and disease.
One of the most significant advantages of HSCs is their ability to self-renew, meaning that they have the ability to divide and create new, identical stem cells. This ensures that the body has a constant supply of blood cells and helps to maintain the integrity of the blood and immune system.
HSCs play a crucial role in the body’s immune system, as they produce the white blood cells that help to prevent and fight infections. They also produce the red blood cells that carry oxygen to the body’s tissues and the platelets that help to form blood clots and prevent bleeding.
HSCs are often used to treat blood disorders, such as leukemia, anemia, and lymphoma, as well as other conditions that affect the blood or immune system, like sickle cell anemia, thalassemia, and severe combined immunodeficiency (also known as “bubble boy” disease).
HSCs play a crucial role in maintaining the health of the blood and immune system, and they are an essential tool in the treatment of a variety of medical conditions. It is important for families to be aware of the potential benefits of HSCs and to consider cord blood banking as a source of HSCs for their family’s future medical needs.
Mesenchymal Stem Cells (MSCs)
MSCs are a type of stem cell found in various tissues throughout the body, including bone marrow, adipose tissue, and cord tissue. MSCs have the ability to differentiate into a variety of cell types, including bone, cartilage, and muscle cells. This makes them ideal for use in regenerative medicine and tissue engineering.
MSCs are being researched for their potential use in the treatment of a variety of medical conditions, including osteoarthritis, spinal cord injuries, and heart disease. MSCs are also being researched for their potential use in the treatment of autoimmune disorders and inflammatory diseases, such as rheumatoid arthritis and Crohn’s disease.
MSCs are different from HSCs in that they do not have the ability to produce blood cells. Instead, they are used for regenerative purposes, to help repair and regenerate damaged tissue. This makes them a valuable resource for families who want to ensure that they have a source of stem cells available for regenerative purposes if they ever need it.
Stem Cell Banking
Stem cell banking, specifically cord blood and cord tissue banking, is the process of collecting and preserving stem cells from the umbilical cord shortly after a baby is born. This can be done through a simple and non-invasive process that does not harm the baby or the mother.

Cord Blood Banking
Cord blood contains a rich source of HSCs, which can be used to treat a variety of medical conditions. Cord blood banking provides a source of HSCs that is readily available and can be used in a transplant if needed. The blood is collected after the baby is born, and the cord is cut. It is then processed, frozen, and stored in a cryogenic facility. This ensures that the HSCs remain viable and can be used in the future if the family who banked the cells ever needs them.
HSCs are the only type of stem cells that have FDA-approved treatments using cord blood.
Cord blood banking is an excellent option for families who want to ensure that their family has a source of HSCs available if they ever need a transplant. It is also a great option for families who have a family history of blood disorders or conditions that affect the blood or immune system.
Cord Tissue Banking
Cord tissue contains MSCs, which have the potential to differentiate into various cell types such as bone, cartilage, muscle, and fat. MSCs are being investigated for potential use in treating a variety of medical conditions including musculoskeletal injuries, autoimmune disorders, and tissue damage. The collected cord tissue is also processed, cryogenically frozen, and stored in a cord tissue bank for future medical use.
MSCs are not FDA-approved for treatment, however, they have shown promise in preclinical and early-phase clinical trials. Some of those trials studied treatment for various conditions, including autoimmune diseases, musculoskeletal injuries, and organ damage. Further research is needed to fully understand the therapeutic potential of MSCs and to develop safe and effective treatments using cord blood MSCs.
Role in Modern Medicine
HSCs and MSCs are two different types of stem cells with distinct characteristics and potential uses. HSCs are responsible for producing blood cells and are often used in the treatment of blood disorders and conditions that affect the blood or immune system. MSCs, on the other hand, are used for regenerative purposes and are being researched for their potential use in the treatment of a variety of medical conditions.
Cord blood banking allows the HSCs to be preserved in a ready-to-use state for years, if not decades. When the cord blood is needed, it can be thawed and used in a stem cell transplant. The advantage of using cord blood is that it is a perfect match for the baby, and it eliminates the need to find a donor. In other cases, the cord blood can also be used for other family members who are a match.
Ultimately, both HSCs and MSCs play a crucial role in modern medicine. By understanding the difference between HSCs and MSCs, and by considering cord blood banking, families can make informed decisions about their family’s health and well-being.
