Fighting Aging Immunity with Stem Cells

What is immunosenescence?

Immunosenescence refers to the gradual deterioration of the immune system brought on by aging. As people get older, the immune system undergoes many detrimental changes.

  • The thymus gland shrinks, resulting in fewer naive T cells that can respond to new pathogens.
  • The ratio of ineffective memory T cells accumulates compared to naive T cells.
  • Chronic inflammation increases, keeping the aged immune system constantly activated.
  • Coordination between different immune cell types declines.
  • Telomeres shorten, reducing the lifespan of immune cells.
  • Stem cells in bone marrow niches diminish, slowing the production of immune cells.

These changes cripple the immune system’s ability to fight infections, respond to vaccines, and keep cancer in check. Older adults suffer from more frequent and severe infectious diseases, have higher cancer rates, and show elevated autoimmunity.

How Stem Cells Combat Immunosenescence

Stem cells from both cord blood and mesenchymal sources exhibit potent immune-boosting and rejuvenating properties that counteract aging immunity.

1. Replenishing Immune Cell Populations

Stem cells can differentiate into essential immune cells that decline with age, like naive T cells, B cells and NK cells. Animal studies find that stem cell treatments can reconstitute aged immune cell populations and restore immune organ function.

In mice, cord blood stem cells increased thymic mass and peripheral T cell populations. Mesenchymal stem cells regenerated atrophied thymus glands in aged rats. This reconstitution of immune cells and organs rebuilds immunity against infections and cancer.

2. Supporting Immune Cell Function

Beyond replenishing cell numbers, stem cells enhance the function of existing immune cells in the elderly. Mesenchymal stem cell treatments in aged mice improved antibody response, natural killer cell activity and T cell proliferation.

Research also shows mesenchymal stem cells promote the health of supporting immune cells like dendritic cells and macrophages that coordinate immune responses. This strengthens the aged immune system at a functional level.

3. Reducing Inflammation and Autoimmunity

Aging brings higher inflammation that disturbs immune balance. But studies find mesenchymal stem cells can reduce inflammatory cytokines and autoantibody production in aged mice and humans. This tempers excessive inflammation to improve age-related immune dysfunction.

4. Reversing Telomere Shortening

Telomeres protect chromosomes but shorten with each cell division, eventually causing cell senescence. Remarkably, peripheral blood stem cell transplantation lengthened telomeres in aged mice, suggesting the aging process can be reversed at a cellular level.

5. Stimulating Growth Factor Production

Animal research indicates stem cell therapies stimulate better cytokine and growth factor production from thymus tissue in aged subjects. These revitalizing biomolecules play a key role in maintaining immune cells and reversing degeneration.

Cutting-Edge Care for Age-Related Immune Decline

The Stem Cell Medical Center provides cutting-edge stem cell therapies to strengthen and rejuvenate aging immune systems. Using advanced treatments with cord blood and mesenchymal stem cells, the Center helps older patients fight immunosenescence.

Seniors receive intravenous infusions of allogeneic cord blood stem cells from young, healthy donors. Cord blood stem cells migrate to bone marrow where they stimulate regeneration and cell division in the aged environment. This replenishes essential immune cells and reactivates bone marrow function.

Mesenchymal stem cells are also administered intravenously. They release growth factors to reduce harmful inflammation and trigger innate immune cells to fight cancer and infections more aggressively.

In addition, stem cell injections into lymph nodes, thymus gland or spinal canal target immune organs directly to restore structural and functional integrity. Patients also undergo nutritional optimization, stress reduction practices and lifestyle education for maximal benefits.

Revolutionary Benefits for Seniors’ Immunity

Pioneering stem cell therapies are producing remarkable enhancements to seniors’ immune strength, health and quality of life:

  • Increased naive T cells and improved T cell function
  • Greater antibody response to influenza vaccine
  • Elevated natural killer cell cytotoxicity
  • Reduced autoantibody levels and suppressed inflammation
  • Renewed thymus gland and bone marrow activity
  • Lengthened protective telomeres
  • Declining cancer antigen load
  • Less frequent colds/flu
  • Improved energy, endurance and recovery from illness
  • Better response to immune-based cancer treatments

By using the body’s own repair mechanisms, the Stem Cell Medical Center restores immune vigor and resilience in seniors. Patients report feeling the “immunological clock” being turned back to more youthful function. Stem cell therapy represents the next generation of healthcare for combating age-related immunodeficiency.


Immunosenescence leaves seniors vulnerable to infectious diseases, cancer, and autoimmunity. Exciting new evidence shows that stem cell treatments can reverse this age-related immune decline by replenishing cells, boosting function, decreasing inflammation, and regenerating organs. The Stem Cell Medical Center provides leading-edge stem cell therapies to rejuvenate aging immune systems and help seniors regain immune strength.
