Treatment of autoimmune diseases with stem cells; It is an innovative treatment method that aims to stop the faulty immune response at the cellular level, repair damaged organs and “reprogram” the immune system (immunomodulation), in which the body perceives its own tissues as a foreign threat and attacks.
This method not only suppresses the symptoms of the disease but also aims to balance the out-of-control mechanisms of the immune system, allowing the body to live in peace with its own healthy tissues.
According to Assoc. Prof. Dr. Erdinç Özek, the biggest advantage of stem cells is that they follow inflammatory signals in the body and go directly to the center of the damage and create an environment of “biological peace” there.
What is Autoimmune Disease and Why Does It Occur?
Autoimmune diseases are chronic conditions that occur when the immune system, which should normally protect the body against bacteria and viruses, chooses to target its own cells, tissues and organs for reasons that are not yet fully understood.
In a healthy body, the immune system can distinguish what is “self” from what is “foreign”; However, in autoimmune processes, this discrimination mechanism is disrupted.
It is scientifically accepted that genetic predisposition, environmental factors (heavy metals, toxins), gut microbiota disorders and chronic stress trigger this erroneous response.
Immune System Attacking Its Own Tissues
When the autoimmune process begins, the immune system begins to produce “auto-antibodies” against certain parts of the body.
This leads to a continuous cycle of inflammation and destruction in the tissues. For example:
Multiple Sclerosis (MS) develops when immune cells attack nerve sheaths.
When it attacks the joint membranes, Rheumatoid Arthritis occurs.
Type 1 Diabetes occurs when it attacks the insulin-producing cells in the pancreas.
According to Assoc. Prof. Dr. Erdinç Özek, while trying to stop this state of aggression with traditional immunosuppressive drugs can completely weaken the system; Stem cell therapy aims to “educate” and “regulate” the system without weakening it.
Common Types of Autoimmune Diseases
While there are over 80 types of autoimmune diseases worldwide, here are some common types that respond most positively to stem cell therapy in the clinic:
Neurological: Multiple Sclerosis (MS), Myasthenia Gravis.
Rheumatologic: Rheumatoid arthritis, systemic lupus erythematosus (SLE), ankylosing spondylitis.
Dermatologic: Psoriasis, vitiligo.
Gastrointestinal: Crohn’s disease, ulcerative colitis.
Endocrine: Type 1 Diabetes, Hashimoto’s Thyroiditis.
The table below compares the standard treatment approach and the stem cell-based regenerative approach in autoimmune diseases:
| Feature | Standard Medication | Stem Cell Therapy |
| Objective | Suppressing symptoms and suppressing immunity. | Regulating immunity and repairing damaged tissue. |
| Mechanism of Action | Chemical intervention. | Biological cell signaling and regeneration. |
| Risk of Side Effects | Risk of organ damage with long-term use. | Low risk profile at the cellular level. |
| Application Process | Usually lifelong daily medication use. | Application in periodic cures. |
Clinical Experience Note (Anonymous Case):
A 45-year-old female patient who has been struggling with active Rheumatoid Arthritis for 5 years and is resistant to standard treatments has undergone a mesenchymal stem cell protocol. It has been observed that 3 months after treatment, the duration of morning stiffness in the joint decreased from 2 hours to 15 minutes and CRP levels, which are markers of inflammation, returned to normal.
How Does Stem Cell Therapy Work in Autoimmune Diseases?
Stem cells follow a multi-layered biological strategy to repair the body’s impaired defense mechanisms in autoimmune diseases.
These cells not only detect damage, but also work like biological regulators that command immune cells to “stop” by using intercellular signaling networks.
According to Assoc. Prof. Dr. Erdinç Özek, the success of stem cells lies in their ability to rehabilitate only malfunctioning cell groups without leaving the body completely vulnerable.
Reorganization of the Immune System (Immunomodulation)
Immunomodulation is the process of reducing the immune system’s overresponse to normal levels.
Mesenchymal stem cells suppress aggressive T and B cells through the anti-inflammatory cytokines they secrete (such as Interleukin-10).
In this process, the immune system is not suppressed (immunosuppression), but rather balanced (immunomodulation). Thus, the body stops attacking its own tissues while maintaining its defenses against real infections from outside.
Suppression of Inflammation and Tissue Regeneration
The main reason why autoimmune diseases become chronic is the endless cycle of inflammation in the tissues.
Stem cells extinguish this destructive inflammation, called the “cytokine storm”, and provide the appropriate environment for tissues to heal.
At the same time, they initiate structural repair by secreting growth factors that trigger tissue regeneration in damaged areas (e.g. nerve sheaths in MS patients or intestinal mucosa in colitis patients).
The “Homing” Ability of Stem Cells and Their Migration to the Damaged Area
One of the most striking features of stem cells is their ability to “homing” (return to the nest).
Stem cells introduced into the body migrate directly to the problem area, following the inflammatory “cries for help” (chemical signals) emitted by damaged tissues.
This smart navigation system increases treatment effectiveness by ensuring that cells work in a targeted manner rather than being distributed throughout the body.
Stem Cell Application Methods Used in the Treatment of Autoimmune Diseases
Since autoimmune diseases are usually systemic (affecting the whole body), treatment protocols prioritize the integration of cells into the circulatory system.
When choosing the method of administration, the patient’s diagnosis, the organs involved and the severity of the disease are taken into consideration.
Intravenous (Intravenous Access) Administration
Intravenous administration is the most preferred “gold standard” method in autoimmune treatments.
When cells enter the circulation through the vein, they can cross the blood-brain barrier (in neurological involvements) or interact directly with systemic immune cells, providing an overall balancing.
Comfort: It is a painless process that does not require surgical intervention.
Access: It allows cells to reach multiple foci, such as the lungs, liver, joints, and nervous system.
Local and Systemic Administration Protocols
Depending on the nature of the disease, the method of administration can be varied:
Systemic Administration: It is used for diseases affecting the entire body or central nervous system, such as lupus (SLE) or MS.
Local Application: In cases such as Rheumatoid Arthritis, local repair can be maximized by injecting some of the cells directly into the affected joint (intra-articular).
The table below compares the methods of administration and recovery times in autoimmune diseases:
| Application Method | Target Disease Groups | Onset of Signs of Improvement |
| Intravenous (Systemic) | MS, Lupus, Type 1 Diabetes, Colitis | 4 – 8 Weeks |
| Local (Joint/Intra-tissue) | Rheumatoid Arthritis, Psoriasis (Specific areas) | 2 – 4 Weeks |
| Combined Protocol | Severe systemic involvement and organ damage | 1 – 3 Months |
According to Assoc. Prof. Dr. Erdinç Özek; “Choosing the right application route in autoimmune diseases means using the ‘homing’ ability of cells efficiently. In particular, mesenchymal cells given intravenously have the potential to reduce the patient’s drug dependence by lowering the body’s overall inflammatory load.”
Which Autoimmune Diseases Can Be Treated with Stem Cells?
Stem cell therapy can be applied in many different pathologies where the immune system is out of control and tissue destruction begins.
The main goal of treatment is to protect the target tissue (nerve, joint, pancreas or intestine), which differs in each disease.
According to Assoc. Prof. Dr. Erdinç Özek, the “immunoreset” (immune reset) effect of stem cells opens a new treatment window in cases where the disease becomes chronic and standard drugs are insufficient.
Multiple Sclerosis (MS) and Rheumatoid Arthritis
MS and Rheumatoid Arthritis are the areas where stem cell studies are most concentrated and clinical returns are most pronounced.
Multiple Sclerosis (MS): Stem cells help protect nerve sheaths (myelin) under immune attack and aim to reduce the frequency of attacks by suppressing neuro-inflammation.
Rheumatoid Arthritis: It stops the destruction of cartilage in the joint and increases the range of motion by reducing inflammation in the synovial tissue.
Type 1 Diabetes, Lupus (SLE), and Psoriasis
Although diseases in this group target very different systems of the body, the cellular response is similar.
Type 1 Diabetes: In cases diagnosed early, it aims to preserve pancreatic function by stopping the immune system from attacking the remaining insulin-producing beta cells.
Lupus (SLE): In this disease with multi-organ involvement, stem cells can stabilize kidney and skin damage by reducing systemic inflammation.
Psoriasis: It regulates faulty immune signals at the cellular level that cause skin cells to multiply excessively.
Inflammatory Bowel Diseases Such as Crohn’s and Ulcerative Colitis
Chronic wounds and inflammation in the intestinal mucosa can quickly respond to the reparative factors of stem cells.
Stem cells aim to prolong the remission (well-being) period of patients by regenerating the epithelial tissue in the intestinal wall and calming the local immune response.
Expected Outcomes and Advantages of Stem Cell Therapy
The biggest advantage of stem cell therapy in autoimmune diseases is its potential to protect the patient from the side effects of heavy immunosuppressive drugs that last a lifetime.
Instead of completely shutting down the body’s defense mechanisms, the treatment only rehabilitates the groups of cells that send faulty signals.
Improvement in Quality of Life and Control of Symptoms
After treatment, chronic fatigue decreases and mobility increases in most patients.
According to Assoc. Prof. Dr. Erdinç Özek, the key to clinical success is symptomatic improvement as well as a decrease in laboratory data (such as auto-antibody levels).
Post-Treatment Recovery Process and Follow-up
While cell transfer is a one-time process, the biological effects are spread over a period of months.
Signaling Phase (0-3 Weeks): Cells spread throughout the body, detecting inflammatory sites.
Regulation Phase (1-3 Months): The immune system is rebalanced, and attacks begin to dilute.
Repair Phase (3-9 Months): Cellular regeneration and functional recovery are observed in damaged tissues.
The table below compares the post-treatment follow-up parameters in autoimmune diseases:
| Disease Group | Clinical Parameter to Monitor | Expected Signs of Improvement |
| Neurological (MS) | MR imaging and EDSS score | Increase in walking distance, decrease in the number of attacks. |
| Rheumatological | CRP, Sedimentation and RF values | Relief of joint pain and morning stiffness. |
| Gastrointestinal | Endoscopic findings | Regression in abdominal pain and bleeding complaints. |
According to Assoc. Prof. Dr. Erdinç Özek; “In autoimmune treatment protocols, we consider the patient as a whole. In order to optimize the body’s response after stem cell transplantation, keeping the patient’s diet and toxin exposure under control ensures the permanence of success.”
Frequently Asked Questions
Will stem cells completely shut down my immune system?
Rather, it regulates the “faulty” working part of the system. Unlike conventional medications, it does not suppress the body’s ability to fight off infections.
Does the treatment offer a definitive solution?
No method in medicine can be 100% guaranteed; However, stem cells are the most powerful biological tool in stopping the progression of the disease and improving the patient’s quality of life.
How long does the application take?
The procedure is usually completed in a clinical setting as a 1-2 hour intravenous infusion. The patient can return to his daily life on the same day.
Are my own cells or donor cells used?
In autoimmune diseases, umbilical cord-derived mesenchymal stem cells are generally preferred because they are “young and dynamic”; because the patient’s own cells may be exhausted by the burden of the disease.
Clinical Experience Note (Anonymous Case):
In a 34-year-old patient who had MS (Multiple Sclerosis) for 10 years and had vision loss and difficulty walking, two cycles of mesenchymal stem cells were administered 6 months apart. In the MRI controls performed after the second cycle, it was noted that the formation of new lesions stopped and the patient could walk 500 meters without support.
