What are autologous and allogeneic cells?
In stem cell therapy, the key factor is the choice of cell source.. There are two main types:
- Autologous cells – come from the patient's own body. They are collected (e.g., from bone marrow, adipose tissue, or peripheral blood), processed, and administered to the same patient.
- Allogeneic cells – come from a donor (this can be a related or unrelated person, or banked cord blood). The cells are collected from a healthy donor, properly prepared, and then administered to another patient.
Why does cell source
selection matter?
Safety and risk of immunological reactions
- Autologous cells are recognized by the body as “its own” because they are genetically identical to other body cells. The immune system does not treat them as foreign, which basically eliminates the risk of rejection or immune response. They do not require the use of immunosuppressive drugs, lowering the risk of infection and other complications. In addition, adipose tissue stem cells (ADSC, MSC) secrete anti-inflammatory and immune response-regulating factors, again reducing the risk of adverse reactions.
- Allogeneic cells derived from umbilical cord blood are immature cells capable of self-renewal and transformation into specialized cell types. They can directly replace damaged tissue and secrete growth factors, cytokines, and exosomes , which support repair processes and regulate the immune response. Cord blood cells are considered "immunologically young," meaning they have a significantly lower capacity to induce rejection compared to adult cells from other donors.Their low immunogenicity stems from the fact that they possess less mature histocompatibility markers (HLA) and naturally secrete immunomodulatory substances that can suppress an excessive immune response in the recipient's body.
Availability and duration of therapy
- Autologous: This therapy requires cell collection, preparation, and their potential expansion, which can increase waiting times. However, it is a personalized method, ideal for patients whose own cells are healthy and functional.
- Allogeneic: Cells can be readily available (e.g., from a cord blood bank), which is particularly important in emergency situations or when the patient's own cells are insufficient or damaged.
Quality and regeneration potential
- Autologous: The quality of the cells depends on the patient’s age and health – in older people or those with chronic diseases, the regenerative potential of the cells may be lower.
- Allogeneic: Cells typically come from young, healthy donors, which may provide higher "biological quality" and a larger cell count.
