Overview of NK Cells

 

 

NK cells, fully known as Natural Killer Cells, are an important component of the human immune system. They are a type of lymphocyte primarily derived from bone marrow. The main functions of NK cells in the human body include:

•Anti-Tumor Effects: Monitoring and killing tumor cells.
•Anti-Viral Infection: Producing cytokines, such as interleukins and interferons, without the need for antigen stimulation during viral infections to combat viral threats.
•Immune Regulation: Regulating the body’s immune function to prevent autoimmune diseases and other immune abnormalities.

Why store immune cells?

 

 

The core value of storing healthy cells lies in breaking biology's time constraints. Over 80% of immune cells are damaged post-chemotherapy, and sudden illness makes acquiring high-quality cells impossible. Cryopreservation halts cellular metabolism at its peak, enabling future CRISPR-enhanced cellular therapies for conditions like Alzheimer’s neuroinflammation or solid tumor infiltration. Choosing facilities licensed by health authorities (e.g., NHCC) is critical—their vapor-phase liquid nitrogen storage and third-party quality systems ensure >85% post-thaw viability for 30 years, transforming biological resources into ultimate life insurance.

03

Storing immune cells far outweighs the importance of saving money

 

 

Storing immune cells is far from an ordinary investment; it's a strategic reserve of life's resources. Immune cells undergo irreversible decline with age: immune diversity decreases by 60% after 35, and by 70, functional T-cell counts are just 5% of youth levels (Nature Aging, 2023). When cancer or severe infection strikes, a patient's weakened immune cells often can't support treatment, but cells frozen in healthier times can be rapidly expanded—this is the biological basis for the success of CAR-T therapies like Novartis's Kymriah in curing leukemia. Unlike the inflationary risk of money, immune cells stored in -196°C liquid nitrogen retain over 90% activity, becoming a "living ammunition depot" for the era of precision medicine.

The Human Immune System

 

 

The human immune system functions as a highly intelligent defense network, composed of two main forces working in synergy. The innate immune arm acts like round-the-clock sentinels; cells such as macrophages and NK cells launch non-specific attacks upon pathogen invasion. The adaptive immune arm operates like special forces: T cells precisely identify antigens on cancer cells to initiate elimination, while B cells produce antibodies to establish long-term immunological memory. This system clears approximately 5,000 cancerous cells daily (Stanford, Cell). However, when aging or disease weakens its efficacy—banking healthy immune cells becomes crucial for rebuilding this defense.
