How safe is using your own (autologous) stem cells, and what side effects should you know about?

Medically, stem cell therapy divides into two main approaches based on cell source: autologous, where cells are harvested from and returned to the same patient, and allogeneic, using cells from another donor. Cheongdam Cell Clinic uses only the autologous approach, harvesting bone-marrow stem cells from the patient's own body across all its programmes — a factor that materially affects overall safety.

The main advantage of the autologous approach is avoiding immune rejection and the risk of infection transmitted from another donor, since all cells used belong to the patient. However, the absence of immune-related risk does not mean there is no risk at all — procedural risks still need to be considered separately.

Cheongdam Cell Clinic explicitly states in its materials that side effects such as swelling, bleeding, or infection may occur after the procedure, at the bone-marrow harvest site or the injection site. These are general risks associated with any procedure that punctures the skin, not risks unique to stem cell therapy alone.

Bone marrow aspiration involves inserting a needle into bone, typically at the pelvis, and patients may feel pain or tenderness at the site for a period afterward. The reinjection step — whether intravenous or targeted local injection — carries the same general risks as any injection-based procedure, such as bruising or localised inflammation.

Factors affecting individual patient safety include age, underlying conditions, use of blood thinners or anticoagulants, infection history, and general health status. Patients with bleeding disorders, blood conditions, or certain medications should disclose this in advance so the physician can properly assess suitability and adjust pre- and post-procedure care.

Internationally, medical regulators emphasise that stem cell treatments lacking sufficient scientific evidence for certain indications should be approached with caution. Patients should ask providers directly about the evidence level behind their programme of interest, and request written risk information before making a decision.

Preparation before the procedure — such as pausing certain medications on medical advice, getting adequate rest, and disclosing any drug or material allergies in advance — helps reduce the risk of side effects. Post-procedure care, including monitoring for abnormal redness or swelling, fever, or pain more severe than expected, and contacting the clinic promptly if these occur, is also an important part of overall safety.

In summary, using the patient's own cells, as Cheongdam Cell Clinic does, genuinely reduces certain risks compared with donor cells, but it does not eliminate risk entirely. Patients should research thoroughly, ask providers direct questions, and make decisions jointly with a physician based primarily on personal health status rather than expected outcomes alone.
