Stem cell therapy involves using specialized cells to repair or replace damaged tissues and modulate the body’s immune response. For autoimmune diseases, in which the immune system mistakenly attacks healthy tissues, this therapy offers a way to reset or regulate immune function. Here is more information about various approaches to stem cell therapy, each with its own protocol:
Using Donor Stem Cells
There are several approaches to treating autoimmune diseases with stem cells. Hematopoietic stem cell transplantation uses stem cells from a healthy donor. The goal of this procedure is to replace the patient’s immune system with a healthy one, and it is typically helpful for severe cases of autoimmune disease. Because the new cells come from a different person, there are some precautions involved.
Careful matching between the donor and recipient is a key part of the process. Doctors use specific markers to find the best possible match, which minimizes rejection risks. Post-transplant monitoring is continuous, and it helps manage potential side effects and track the new immune system’s development.
The procedure itself requires conditioning the patient’s body with chemotherapy to suppress the existing immune system before the transplant. This preparative regimen is intense, so it carries its own set of risks. Patients receive donor stem cells via infusion, similar to a blood transfusion.
Using Patient Stem Cells
Autologous mesenchymal stem cells (MSCs) are sourced from the patient’s own body, often from bone marrow or fat tissue. These cells have properties that may help regulate the immune system, and they can be expanded in a lab before being reintroduced to the patient. Since the cells are from the patient’s own body, the risk of rejection is very low.
The stem cell therapy process begins by collecting MSCs, which specialists isolate and culture for several weeks. Once a sufficient number of cells is available, they go back into the patient. This approach focuses on modulating immune responses rather than completely replacing the immune system, so it generally has a better safety profile than allogeneic HSCT.
Creating Engineered Cells
Researchers are developing methods to create specialized immune cells, which are derived from a patient’s skin or blood cells. They engineer cells in a laboratory to perform specific functions. This precise targeting could offer a new way to manage immune responses. Engineered cells may:
- Suppress specific inflammatory pathways.
- Target only the malfunctioning immune cells.
- Promote tissue repair at sites of damage.
Promoting Healing
Another approach focuses on modulating the cellular microenvironment to encourage the body’s natural healing. This technique may use biomaterial scaffolds and stem cells to direct tissue regeneration, and it guides the cells to the precise location where they are needed. By creating a supportive structure, these scaffolds help transplanted cells survive and function correctly.
