What is Stem Cell Therapy?
Stem cell therapy is an innovative approach used in the treatment of various diseases, and in this method, stem cells are used to repair or regenerate damaged or diseased tissues of the body. This therapy can be especially effective in areas such as blood and immune system diseases. The basic steps and features of stem cell therapy are as follows:
Stem Cell Collection: Treatment usually begins with collecting stem cells from the patient or a suitable donor. These cells can be embryonic stem cells, adult stem cells or iPS cells (induced pluripotent stem cells).
Cell Processing and Culturing: The collected stem cells are processed and propagated in the laboratory environment. This process allows cells to be produced in the desired types and quantities.
Application to the Patient: The processed stem cells are transplanted to the patient. This stage may be in the form of intravenous infusion or injection directly into the damaged tissue.
Monitoring and Evaluation: After stem cell transplantation, the patient’s recovery process is closely monitored. The effectiveness of the treatment and possible side effects are evaluated.
Stem cell therapy has been used for many years in the form of bone marrow transplantation, especially in the treatment of diseases such as blood cancer (leukemia). It is also among the potential treatment options for conditions such as Parkinson’s disease, Type 1 diabetes, Alzheimer’s disease, heart diseases and some spinal cord injuries.
This treatment method holds great promise as it has the ability to reconstruct and repair. However, it also involves some risks and challenges, such as uncontrolled growth of cells, immune responses, and ethical issues. Therefore, research on stem cell therapy is still ongoing and applications in this field are constantly being improved. Top of Form
What is Stem Cell?
A stem cell is a special type of cell that has the ability to transform into various cell types of the body. These cells can renew themselves and differentiate. There are two main types: While embryonic stem cells can develop into all cell types; Adult stem cells can often differentiate into cells specific to the tissue in which they are found. Stem cell research is of great importance to offer potential solutions in the treatment of diseases. Top of Form

- Embryonic Stem Cells
Source: Embryonic stem cells are generally obtained from unused embryos produced during in vitro fertilization.
Obtaining Process: Cells in the blastocyst stage of the embryo are collected by carefully separating them. These cells have the capacity to transform into any type of cell in the human body.
- Adult Stem Cells
Resources:
Bone Marrow: One of the most common sources. It is especially used to renew blood cells.
Peripheral Blood: With the use of certain stimulant medications, stem cells are released into the bloodstream and can then be collected.
Adipose Tissue: Stem cells can be isolated from adipose tissue obtained through lipoaspiration.
Other Tissues: Adult stem cells can also be obtained from other organs and tissues such as liver, brain and skin.
- Cord Blood Stem Cells
Collection Method: Stem cells can be collected from the blood taken from the umbilical cord during the birth of the baby. These cells are used especially in the treatment of hematological diseases.
- Induced Pluripotent Stem Cells (iPS Cells)
Method: It is achieved through genetic reprogramming of existing adult cells.
Process: By insertion or activation of certain genes, mature cells, such as skin cells, acquire properties similar to embryonic stem cells.
General Steps of the Acquisition Process
Collection: Depending on the source, cells are collected through surgery, blood draw, or tissue biopsy.
Processing and Culturing: Collected cells are processed, purified, and propagated in the laboratory.

Frequently asked Questions
Which Orthopedic Patients Should Be Applied to Stem Cell Treatment?
Stem cell therapy can be used in orthopedic conditions such as osteoarthritis, especially where joint cartilage is damaged. It may also be effective in healing tendon injuries, ligament damage, meniscus tears and bone fractures. This treatment is designed to help repair and regenerate damaged tissue.
On which areas of the skin can fat injection and stem cell procedure be applied?
Stem cell treatment with fat injection can be used for skin regeneration and aesthetic improvements. This method is generally applied for purposes such as reducing facial wrinkles, plumping lips, shaping cheeks and improving skin tone. It can also be used to heal scars and damaged tissue on the skin.
How does fat injection and stem cell procedure affect the skin?
Stem cell procedure with fat injection can improve the appearance and texture of the skin. Stem cells can promote skin renewal and tissue repair, making skin look younger and more vibrant. Fat cells improve the aesthetic appearance of the skin by adding volume and fullness. Additionally, this process can increase skin elasticity and help reduce wrinkles.
