What Is Cell Therapy and How Does It Work

Cell therapy is a field of regenerative medicine that uses living cells to support tissue repair, reduce inflammation, and improve body functions. The most commonly used cells include cord blood stem cells, mesenchymal stromal cells (MSCs) from umbilical cord and placental tissue, as well as MSCs derived from adipose tissue and the patient’s bone marrow.

Unlike symptomatic treatment, cell therapy is aimed at activating the body’s natural repair mechanisms. That is why this method is actively used in neurology, orthopedics, rehabilitation, immunology, and longevity programs.

How Cell Therapy Works

Cell therapy works through biologically active signals released by stem cells after administration. These cells do not simply “replace” damaged tissues — they trigger the body’s own repair processes.

Main mechanisms of action of cell therapy:

• reduction of inflammation
• stimulation of tissue regeneration
• improvement of blood supply
• activation of the body’s own stem cells
• support of nervous system recovery
• modulation of immune response
• reduction of tissue scarring

Therefore, cell therapy may be used in various diseases and conditions associated with tissue damage or chronic inflammation. Cell therapy is still often perceived as an adjunctive treatment — in cases where standard therapy does not help or causes significant harm to the body.

What Types of Cells Are Used in Cell Therapy

Different types of cells are used in regenerative medicine. The choice depends on the clinical situation, patient age, and treatment goals. The main selection criteria should include therapeutic activity, safety, and ethical sourcing of cells. These criteria are best met by stem cells from postnatal tissues (cord blood, umbilical cord, placenta) as well as stem cells derived from the patient’s own body.

Mesenchymal Stromal Cells (MSCs) From Umbilical Cord and Placenta

MSCs have anti-inflammatory effects, support tissue regeneration, and modulate the immune system. This is one of the most commonly used cell types in cell therapy. These cells can be obtained from umbilical cord and placental tissues collected after childbirth. These are considered the most valuable type of MSCs because they are the youngest and most biologically active.

Cord Blood Cells

Cord blood contains immune and hematopoietic cells, as well as signaling factors that support recovery. These cells are obtained from cord blood remaining in the umbilical cord and placenta after childbirth.

Patient’s Own Mesenchymal Stromal Cells (MSCs)

These cells can be obtained from adipose tissue or bone marrow and used for autologous therapy. They usually have lower regenerative potential compared to postnatal MSCs, and their effectiveness depends on the patient’s age and lifestyle. They are most commonly used in orthopedics and anti-aging programs.

When Cell Therapy Is Used

Cell therapy may be considered as part of комплексного лікування (complex treatment) for various conditions:

• neurological disorders
• autism spectrum disorder (ASD)
• cerebral palsy
• stroke recovery
• traumatic brain injury
• orthopedic joint disorders
• osteoarthritis and degenerative changes
• autoimmune diseases
• chronic inflammation
• slow recovery after injuries
• anti-aging and longevity programs

Cell therapy is usually combined with rehabilitation, medication, and other treatments. Comprehensive programs improve the chances of recovery and enhance quality of life.

How Cell Therapy Is Performed

The cell therapy process consists of several stages:

1. Consultation with a specialist
2. Medical documentation review
3. Selection of cell type and dose calculation
4. Cell administration
5. Post-procedure monitoring

Cells may be administered in different ways depending on indications:

• Intravenous
• local injection (joint, peribulbar, or injury site)
• intrathecal (in neurology, spinal injuries, multiple sclerosis)
• intramuscular

The administration method is determined individually.

Is Cell Therapy Safe?

Modern cell therapy using tested cells and medical supervision is considered safe. Like any medical intervention, cell therapy has indications and limitations, and the decision is made individually by the physician and patient.

Mesenchymal stromal cells have low immunogenicity and are generally well tolerated even in allogeneic use. That is why they are actively studied in regenerative medicine.

When Results of Cell Therapy Appear

The effect of cell therapy usually develops gradually and directly depends on the regenerative capacity of the body and the source of stem cells (their biological potential). Initial changes may appear within weeks or months after administration, but effectiveness is usually evaluated at 3, 6, 12, and 18 months.

The result depends on:

• diagnosis
• patient age
• degree of damage
• cell type and dose
• accompanying rehabilitation

Cell therapy is aimed at initiating natural repair processes, therefore the effect develops gradually.

Frequently Asked Questions About Cell Therapy

Does cell therapy completely cure diseases?

Cell therapy is not always a complete cure. It is used to support recovery and improve functional status.

Is cell therapy suitable for children?

Yes, cell therapy is used in pediatrics, especially for neurological disorders and primary autoimmune conditions.

Can cell therapy be repeated?

Yes, in some cases treatment is performed in courses.

Is cell therapy suitable for adults?

Yes, cell therapy is used in both children and adults. In adults, stem cells are used for treatment, rejuvenation, and longevity.

Conclusion

Cell therapy is a modern tool of regenerative medicine that helps the body recover using living cells. It is applied in neurology, orthopedics, rehabilitation, and anti-aging programs and is most often part of comprehensive treatment.
