Autologous Fibroblast and Stem Cell Treatment in Ankara, Turkey

Autologous fibroblast and stem cell treatment is an advanced biotechnological application in which biological materials obtained from a person’s own cells are used for skin rejuvenation and tissue renewal. By targeting regeneration at the cellular level, this treatment creates a natural anti-aging effect.

In autologous fibroblast treatment, fibroblast cells are multiplied in a laboratory environment from a small skin sample taken from the patient. These cells are injected into the skin to increase collagen and elastin production. The application is an effective method for reducing fine wrinkles and skin laxity.

Stem cell treatment is performed using mesenchymal stem cells obtained from adipose tissue. These cells accelerate tissue repair and reduce the signs of aging on the skin. At the same time, they also have a supportive effect in the treatment of wounds, burns, and scars.

Since both treatments are autologous, the risk of allergic reaction is low. The application should be performed under sterile conditions and by experienced specialists. Treatment results usually appear within a few months and provide long-term improvement in skin quality.

What Is Autologous Fibroblast and Stem Cell Treatment?

Autologous fibroblast and stem cell treatment is a regenerative method applied by multiplying cells obtained from the person’s own tissue in a laboratory environment and injecting them under the skin. This treatment is especially preferred to reduce signs of aging, increase skin elasticity, and support tissue repair. Since it is a natural and biological approach, it can provide long-lasting and safe results.

Why is autologous cellular treatment safe?

Autologous cellular treatment is one of the cornerstones of modern regenerative medicine. Its principle is very simple: using cells or tissues taken from an individual’s own body. These cells are sometimes used as they are and sometimes passed through a laboratory process (for example, multiplied or enriched) and then given back to the same individual for a treatment or cosmetic purpose.

The greatest strength of this approach is biological compatibility. It is not possible for your body to perceive its own cell as “foreign.” Some synthetic fillers or animal-derived (for example bovine) collagens used in the past carried the risk of causing a reaction in the body. For this reason, allergy testing had to be performed before such treatments. Risks such as allergic reactions, abscess formation, or the body trying to reject that substance (foreign body granuloma) were always on the table.

Autologous treatments completely overcome these limitations. Since the body recognizes its own cells, the risk of allergy or hypersensitivity disappears. At the same time, there is no risk of external contamination or infection (as long as the procedure is performed under sterile conditions). This places autologous treatments in an extremely superior position in terms of safety profile. The main goal is to use the specific regenerative capacity of the selected cell type (fibroblast or stem cell) to repair damaged skin tissue, restore lost volume, and rejuvenate the skin as a whole.

What is the difference between the main autologous cells used in skin rejuvenation, namely Fibroblasts and Stem Cells?

When we talk about cellular treatments in dermatology, we actually focus on two main cell groups: Dermal Fibroblasts and Adipose-Derived Stem Cells (ADSCs).

These two cell groups use fundamentally completely different methods to renew the skin. Which treatment is chosen depends on the patient’s needs and the targeted outcome.

Think of it this way: Fibroblasts are like the “production factories” of the skin. Stem cells are more like “signal-giving managers” or “repair team chiefs”:

Dermal Fibroblasts (Structural Factories)

Fibroblasts are the main cells located in the dermis, the middle layer of our skin. They have only one basic task: to produce the support structure of the skin, the structure called the “Extracellular Matrix” (ECM). This structure consists of:

• Collagen (for the skin’s strength and structure)
• Elastin (for the skin’s elasticity)

Glycosaminoglycans (for the skin’s moisture-retention capacity)

Fibroblast treatment (AFT) means adding more “production factories” directly into the skin. These cells are specialized cells designed to restore and repair the physically missing structure.

Adipose-Derived Stem Cells (ADSCs) (Signal-Giving Managers)

Stem cells, on the other hand (generally obtained from adipose tissue), unlike fibroblasts, do not directly produce a structural component (such as collagen). Their power comes from the signals they send to their environment. Stem cells secrete powerful signaling molecules into their surroundings. These signals do the following:

• Powerful anti-inflammatory effect
• Secretion of various growth factors
• Antioxidant effect
• Promotion of the formation of new blood vessels (Neoangiogenesis)

Stem cell treatment (ADCT) means adding “manager” cells to the skin. These cells instruct the existing surrounding cells (including the existing fibroblasts) to “work harder,” “heal faster,” and “revitalize the area.” They promote the overall health and regeneration of the tissue.

The clinical result of this mechanical difference is very important. Fibroblast treatment (AFT) offers an ideal direct replacement strategy for regional and deep structural deficiencies such as deep acne scars or established deep wrinkles. Stem cell treatment (ADCT), on the other hand, is superior for improving the overall quality of the skin (texture, elasticity, radiance) and globally enhancing skin health.

How does Autologous Fibroblast Treatment (AFT) work?

Autologous Fibroblast Treatment (AFT) is based on injecting the person’s own healthy and youthful fibroblasts, multiplied in the laboratory, directly into the area where they are needed (for example into a wrinkle line or acne scar).

These injected fresh “production factory” cells have two main roles:

• Direct Production: As soon as they are injected, they immediately begin to produce new collagen and elastin in the deficient area.
• Stimulation: They also stimulate the other existing fibroblast population in the area, which may have become “slowed down” or “tired” due to age, encouraging them to increase their production of supportive tissue.

This is a dual-effect process that strengthens the architecture of the skin by both adding new workers and motivating the old ones. This treatment mimics the skin’s own self-repair mechanism, but it does so in a much stronger and more concentrated way.

How are fibroblast cells obtained and produced for treatment?

One of the most important advantages of AFT is that the production process is logistically simple and reliable.

• Sample Collection (Sourcing)

A major surgical procedure is not required to obtain fibroblasts. Generally, it is sufficient to take a single dermal punch biopsy (approximately 3-4 mm in diameter, a tiny piece of tissue) from a closed area that does not see the sun, such as behind the ear or the inner arm, under a small local anesthesia. This minimally invasive procedure provides a sufficient source of autologous cells for all future clinical applications (sometimes for 2-3 treatment sessions).

• Culture and Multiplication (Ex-Vivo)

This tiny piece of tissue is sent to special cell laboratories approved by the Ministry of Health and having GMP (Good Manufacturing Practices) standards. Here, fibroblasts are separated from the tissue and begin to be multiplied in special nutrient media (culture environments).

Fibroblasts are remarkably robust cells compared to stem cells. They multiply rapidly in the laboratory environment; the doubling time of a fibroblast population is on average between 16 and 24 hours. This is significantly faster than the proliferation rate of stem cells (48+ hours).

These features (easy sourcing, robustness, rapid multiplication) make AFT a more accessible and reliable option. This production consistency also makes the “cell banking” model possible. That is, cells taken today can be multiplied and frozen and reused years later when needed (for example, for a booster dose 5 years later).

In which areas is autologous fibroblast treatment most effective?

Since fibroblast treatment focuses on directly correcting the lack of “structure,” it is particularly powerful in certain indications. Some of the conditions in which fibroblast treatment is most preferred and provides the best results are:

• Deep acne scars (depressed, atrophic scars)
• Nasolabial folds (lines around the nose)
• Marionette lines (lines running from the corners of the mouth to the chin)
• Prominent facial wrinkles (especially static, established rhytids)
• Depressed scars formed after surgery or trauma
• Areas experiencing regional volume loss in the skin
• Upper lip “barcode” lines

Is autologous fibroblast treatment safe and how long-lasting are its results?

Autologous treatments already have a very strong safety profile because of their biological origin. In clinical studies conducted for AFT, no serious side effects were reported other than temporary minimal redness or bruising at the injection site.

An important advantage of AFT is that it has also been recognized by regulatory authorities. For example, the autologous fibroblast treatment called Azficel-T (commercially known as LaViv®) received approval from the U.S. Food and Drug Administration (FDA) for the correction of nasolabial folds (lines around the nose). This FDA approval is an important legal precedent showing that AFT is a proven, validated, personalized cell therapy product whose efficacy and safety have been demonstrated.

Permanence:

One of the most attractive aspects of this treatment is its durability. Clinical studies have documented that the improvements provided by AFT injections last at least 12 months.

In a comprehensive study, significant improvement was observed after 6 months in patients treated for wrinkles and acne scars, and this effect remained stable for up to 24 months (2 years).

Patient satisfaction data also support this durability. In a 5-year telephone follow-up, 65.2% of the participants treated for wrinkles still rated their treatment areas as “good” or “excellent.”

However, the situation is slightly different in acne scar treatment. Satisfaction with acne scars dropped to 30% over the 5-year period. This does not mean that the treatment failed. It shows that complex and deep fibrotic tissues such as acne scars require a more complex repair process than wrinkle treatment and that periodic maintenance sessions may be needed in these patients.

What is Adipose-Derived Stem Cell Treatment (ADCT) and how does it work?

Adipose-derived cellular treatments (ADCT) drive dermatological rejuvenation primarily through their paracrine effects, that is, their ability to “send signals” from cell to cell. The injected stem cells (ADSCs) secrete powerful growth factors and anti-inflammatory molecules that improve the local tissue microenvironment.

This biological signaling stimulates tissue renewal, encourages existing cells to secrete proteins such as collagen, increases the skin’s moisture and density, and improves blood supply by supporting the formation of new capillaries (neoangiogenesis).

The aim of this treatment is not to directly “fill” like fibroblasts, but to improve the overall quality and health of the skin. It is regarded as a promising minimally invasive method especially for increasing elasticity, firmness, and dermal thickness.

How are Stem Cells obtained for treatment?

Unlike the simple punch biopsy in fibroblast treatment, the application of ADCT requires an initial surgical procedure: the collection of adipose tissue through liposuction. This is generally a more invasive procedure than fibroblast collection, usually from the abdomen or hips.

The obtained fat (lipoaspirate) is then processed. As a result of this process, two types of products can be obtained:

• SVF (Stromal Vascular Fraction): A heterogeneous mixture obtained from adipose tissue containing many different cell types such as stem cells, immune cells, and preadipocytes. It can be used immediately.
• Isolated ADSCs: Purified and multiplied stem cells obtained by subjecting the SVF to a more advanced culture process in the laboratory.

Are there risks or limitations of Stem Cell treatment?

The clinical predictability of ADCT is more limited compared to AFT, and some important points should be taken into consideration.

First of all, the fact that the procedure is “natural” does not mean that it is “risk-free.” Fat harvesting is a surgical procedure and carries some risks. These risks are:

• Bleeding
• Embolism
• Clot formation
• Hematomas
• Infection
• Edema (swelling)

Secondly, the effectiveness of this treatment depends on how well the local microenvironment responds to these “signals,” depending on the patient’s age and tissue health. This may cause high variability (heterogeneity) in the results from patient to patient.

A third important point is the property of stem cells to promote “neoangiogenesis” (new blood vessel formation). Although this is generally a desired effect for revitalizing the skin, these treatments should be used with caution in patients with an oncological (cancer) history because of the theoretical potential to affect tumor growth or metastasis.

Finally, unlike AFT (which has an FDA-approved protocol), stem cell treatments (SVF preparation methods, dosages, application protocols) do not yet have complete standardization. This can lead to inconsistent results between studies.

Which autologous treatment is better: Fibroblast or Stem Cell?

Choosing between these two autologous treatments is not about one being “better” than the other, but about what the therapeutic goal is. Both are valuable tools, but they are used for different purposes.

• Fibroblast Treatment (AFT) Should Be Preferred in the Following Situations:

If the clinical goal is to structurally repair fixed, defined volume deficiencies and scars, AFT should be preferred. To fill “voids” such as deep nasolabial folds, depressed acne scars, or prominent scars, directly collagen-producing “factory” cells are needed. AFT provides a predictable and measurable volumetric response. Its logistics (punch biopsy) are simpler and safer.

• Stem Cell Treatment (ADCT) May Be Considered in the Following Situations:

If the clinical goal is to improve the overall quality, texture, and elasticity of the skin and to give the skin a “bio-stimulation,” ADCT may be considered. In conditions such as thin, dull, lifeless skin and general loss of elasticity, these “signal-giving” cells may be more appropriate for enhancing the skin’s general health and radiance. However, it should not be forgotten that ADCT is not a structural “filler,” but a “healer.”

Can autologous treatments be combined with procedures such as Laser or Microneedling?

Yes, and the most effective approaches in modern regenerative dermatology generally arise from this synergy. Combining controlled mechanical or thermal dermal damage (with laser or microneedling) with powerful biological stimulation (autologous cells) can provide much superior results than treatments performed alone.

Fractional lasers or microneedling devices open thousands of microchannels in the skin and initiate a controlled wound healing process. This process increases both the penetration and effectiveness of topically applied autologous materials (stem cells, SVF, or PRP derivatives) under the skin.

One of the greatest benefits of this combination is that it accelerates the recovery process. The biggest limitation of aggressive skin resurfacing techniques such as CO2 laser is the long recovery period that occurs after the procedure (redness, edema), in other words “downtime.” Applying autologous cellular components (especially ADCT/SVF) immediately after the procedure actively regulates this inflammatory response, accelerates the repair of the upper layer of the skin, and minimizes discomfort.

This combination approach allows more aggressive and effective energy devices to be used safely and increases patient satisfaction because the recovery period is dramatically reduced.
