What is Autologous Cell Therapy?
Autologous cell therapy is a type of regenerative medicine treatment that uses a patient's own cells to treat disease or injury. In autologous cell therapy, cells are extracted from the patient and processed in a laboratory before being administered back to the patient to help healing or treat a disease.
Extracting and Processing Cells
The first step in Autologous Cell Therapy is to extract cells from the patient's own body. Common cell types used include bone marrow stem cells, blood stem cells, adipose (fat) tissue stem cells, and skin cells. The cells are extracted through a minimally invasive procedure, such as a bone marrow biopsy or liposuction.
Once extracted, the cells are processed in a laboratory. This processing may involve selecting certain cell types, like stem cells, and multiplying their numbers through cell culture. The cells are also tested to ensure viability and safety before being prepared for administration back to the patient.
Administering Cells Back to the Patient
After processing, the purified autologous cells are administered back to the patient. Common administration methods include injection directly into the site of injury or disease, intravenous infusion into the bloodstream, or application topically to the skin. The cells can then help promote healing through various mechanisms like reducing inflammation, stimulating growth of new tissues, and recruiting the patient's own stem cells.
Potential Benefits of Autologous Cell Therapy
Autologous cell therapy offers some key potential benefits compared to other treatments:
- No risk of rejection - Since the cells come from the patient's own body, there is no risk of the immune system rejecting the transplant. This avoids the need for immunosuppressive drugs.
- Personalized treatment - A patient's own cells can be selected and engineered to best treat their individual disease characteristics and physiology. A "one size fits all" approach is avoided.
- Multipotent cells - Adult stem cells used in therapy, like mesenchymal stem cells, have the potential to develop into several mature cell types and aid regeneration of multiple tissues.
- Avoidance of ethical issues - In autologous therapy, embryos or fetal tissue are not involved so some of the ethical issues surrounding stem cell research are circumvented.
Common Applications of Autologous Cell Therapy
Some medical conditions where autologous cell therapy is being investigated or applied clinically include:
Orthopedic Injuries and Arthritis
For injuries like tendon/ligament tears and arthritis, mesenchymal stem cells extracted from bone marrow or adipose tissue can help regenerate tissues and reduce pain or need for joint replacement when injected into affected areas.
Cardiovascular Disease
After a heart attack, stem cells administered directly into the heart muscle through a minimally invasive catheter help repair damage by transdifferentiating into new heart muscle cells and blood vessels.
Neurological Disorders
Conditions like multiple sclerosis and stroke may be aided by stem cells' ability to reduce inflammation in the nervous system, secrete neuroprotective factors, and potentially replace lost neurons or glial cells when administered systemically or directly into the spinal cord or brain.
Diabetes and Liver Disease
Stem cells show promise for treating diabetes by engrafting into the pancreas to produce insulin or treating chronic liver disease by replacing damaged hepatocytes to improve liver function and forestall transplantation.
Skin Wounds and Ulcers
Extracted skin cells or stem cells grown from skin biopsies hold potential for treating chronic non-healing wounds and ulcers when applied topically, helping regeneration of dermal and epidermal layers.
Advanced Clinical Trials and Future Potential
While autologous cell therapy is still under investigation, many clinical trials have reported promising results. Larger phase 3 trials will provide more conclusive evidence on efficacy for specific applications. As processing techniques improve cell quality and viability, more cell types may become viable for treatment. With further research refining optimal cell types, dosages, and administration methods, autologous cell therapy has great potential to transform treatment of chronic and currently incurable conditions.
