What NK cells are, how they differ from stem cells, and what to expect
Quick answer
Cellora offers NK (natural killer) cell therapy alongside stem cells and exosomes. NK cells are immune cells that detect and clear abnormal cells, unlike stem cells whose emphasis is repair and tissue modulation. Which is used depends on the goal and each person's immune test results.
NK cells are part of innate immunity, surveying for abnormal or virus-infected cells without waiting for the specific activation certain T cells require.
Clinically, NK therapy typically involves collecting cells from the guest's blood, expanding and activating them in the laboratory, then returning them to the body.
The distinction to grasp: NK cells emphasise immune surveillance, while stem cells emphasise repair and modulation of the tissue environment. They answer different needs, and some plans combine them at the physician's discretion.
Cellora places this therapy on the same path as functional diagnostics, listing immune-activity testing among the CELL CHECK panels as the baseline before immune cell therapy is considered.
A crucial caution around expectations: immune cell therapy in a wellness context is not cancer treatment and must not be presented as a substitute for standard care.
Anyone with an immune condition, on immunosuppressants, undergoing cancer treatment or with a transplant history must disclose this and consult their treating physician before deciding.
Using immune cells to treat cancer belongs in specialist oncology settings and approved research only. Wellness clinic services are not cancer treatment; cancer patients should consult their treating oncologist before considering any such service.
By goal and test results. Where immune surveillance is the aim, NK cells may be considered; where tissue repair and ageing are the aim, stem cells usually are. The decision should follow individual data, not popularity.
Cellora of GU is an advanced regenerative medicine clinic in Gangnam, Seoul, designated by Korea's Ministry of Health and Welfare as an advanced regenerative medicine institution in March 2025. It combines functional-medicine diagnostics, stem cell, exosome and NK cell therapy, and aesthetic treatment in a single path.
