Our Cellular Therapy and Stem Cells for Autoimmune and Connective Tissue Diseases with Organ-specific progenitor stem cells are derived from various tissues and are used in clinical settings to treat autoimmune and connective tissue diseases. The most common sources of these stem cells include bone marrow, adipose tissue, umbilical cord blood, and peripheral blood. Here is a detailed explanation of each source and its clinical applications:
– Bone Marrow Aspiration: The procedure involves extracting bone marrow from the hip bone (iliac crest) under local or general anesthesia. The collected bone marrow contains HSCs and MSCs.
– Liposuction: Adipose tissue is collected through a minimally invasive liposuction procedure. The tissue is then processed to isolate and expand MSCs.
– Mesenchymal Stem Cell Therapy: Adipose-derived MSCs are used in the treatment of autoimmune and connective tissue diseases due to their strong anti-inflammatory and immunomodulatory effects. They are particularly used in conditions like RA and systemic sclerosis (scleroderma)[63-67].
– Cord Blood Banking: After childbirth, blood is collected from the umbilical cord and placenta. The collected cord blood is processed to extract HSCs and MSCs and then cryopreserved for future use.
Peripheral blood contains hematopoietic stem cells (HSCs) that can be mobilized and collected for transplantation. This method is less invasive compared to bone marrow aspiration.
Collection:
– Apheresis: Patients or donors are treated with growth factors (such as granulocyte-colony stimulating factor, G-CSF) to mobilize HSCs from the bone marrow into the peripheral blood. Blood is then collected via apheresis, a process that separates stem cells from other blood components.

Cellular Therapy and Stem Cells for Autoimmune and Connective Tissue Diseases represents a novel approach in the treatment of autoimmune diseases, where the immune system mistakenly attacks the body’s own tissues. This therapy aims to reset the immune system, reducing its aggressive stance against the body’s own cells. Here’s a more detailed look at how Cellular Therapy and Stem Cells are being explored or utilized in the treatment of specific autoimmune diseases:
1. Multiple Sclerosis (MS)
Multiple sclerosis is a chronic autoimmune condition where the immune system attacks the protective sheath (myelin) that covers nerve fibers, causing communication problems between the brain and the rest of the body. High-dose immunosuppressive therapy followed by autologous hematopoietic stem cell transplantation (HSCT) has shown promise in treating aggressive forms of MS. This procedure involves the collection of a patient’s own hematopoietic stem cells, followed by the administration of chemotherapy to deplete the immune system, and then the re-infusion of the stem cells to rebuild the immune system with the hope of resetting it to stop it from attacking the myelin.
2. Type 1 Diabetes
Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys insulin-producing beta cells in the pancreas. Research into stem cell therapy for type 1 diabetes focuses on two main approaches: protecting the remaining beta cells and regenerating or replacing beta cells. One method involves using stem cells to create new beta cells in the lab that can be transplanted into patients. Another approach aims to use stem cells to modulate the immune system’s attack on beta cells.
3. Rheumatoid Arthritis (RA)
Rheumatoid arthritis is a chronic inflammatory disorder affecting many joints, including those in the hands and feet. While stem cell therapy research in RA is less advanced than in MS, it focuses on using mesenchymal stem cells (MSCs) to modulate the immune system and reduce inflammation. Early research suggests that MSCs can help regulate immune system activity and promote the regeneration of damaged tissues, though more studies are needed to confirm these effects and determine the best treatment protocols.
4. Systemic Lupus Erythematosus (SLE)
SLE, or lupus, is a systemic autoimmune disease that can affect the joints, skin, brain, lungs, kidneys, and blood vessels. The use of autologous HSCT has been explored in severe cases of SLE that do not respond to conventional treatments. The goal is to reset the immune system to stop it from attacking the body’s tissues. Early results have been promising, showing a reduction in disease activity and, in some cases, remission. However, the procedure carries significant risks and is considered for severe, life-threatening cases.
5. Crohn’s Disease
While primarily classified as an inflammatory bowel disease, Crohn’s disease has an autoimmune component, where the immune system attacks the gastrointestinal tract, causing inflammation. Stem cell therapy, particularly autologous HSCT, has been explored as a treatment for patients with Crohn’s disease who do not respond to standard therapies. The approach aims to reset the immune system to reduce inflammation and alleviate symptoms.
8.8 Scleroderma (Systemic Sclerosis)
Scleroderma is a chronic autoimmune disease characterized by fibrosis of the skin and internal organs, vasculopathy, and immune dysregulation. Autologous hematopoietic stem cell transplantation (HSCT) has emerged as a promising therapy for severe, progressive cases. HSCT involves harvesting the patient’s hematopoietic stem cells, immunosuppressive chemotherapy to ablate the immune system, and re-infusing the stem cells to rebuild a less autoreactive immune system. Studies have shown HSCT can improve skin scores, lung function, and overall survival in selected patients.
8.9 Fibromyalgia (FM)
Fibromyalgia is a chronic pain disorder characterized by widespread musculoskeletal pain, fatigue, sleep disturbances, and cognitive issues. Recent research explores the potential role of mesenchymal stem cells (MSCs) in alleviating symptoms by modulating the central nervous system’s pain processing pathways and reducing systemic inflammation. While MSC therapy remains experimental, early studies suggest reduced pain levels and improved quality of life for fibromyalgia patients.
8.10 Chronic Fatigue Syndrome (CFS)
Chronic fatigue syndrome is a debilitating condition characterized by persistent fatigue not improved by rest, alongside cognitive impairment and other systemic symptoms. MSC therapy has shown potential to modulate the immune system, reduce inflammation, and promote mitochondrial repair, addressing some underlying mechanisms of CFS. Pilot studies suggest improved energy levels and symptom relief, though larger trials are needed to confirm efficacy.
8.11 Ankylosing Spondylitis (AS)
Ankylosing spondylitis is a chronic inflammatory condition primarily affecting the spine and sacroiliac joints, leading to pain and stiffness. HSCT has been explored for refractory AS, using high-dose immunosuppressive therapy to reset the immune system. Preliminary findings indicate reduced disease activity and improved spinal mobility in severe cases unresponsive to conventional biologic therapies.
8.12 Antiphospholipid Syndrome (APS)
Antiphospholipid syndrome is an autoimmune disorder characterized by recurrent thrombosis and pregnancy complications. MSC therapy is being investigated for its anticoagulant and immunomodulatory properties, aiming to reduce thrombotic events and mitigate pregnancy risks. Early-phase trials suggest potential benefits, though long-term outcomes and safety remain under evaluation.
8.13 Dermatomyositis (DM)
Dermatomyositis is an inflammatory myopathy causing muscle weakness and characteristic skin rashes. HSCT has shown promise in severe, treatment-resistant cases, providing durable remission by resetting the immune system. Studies report improvements in muscle strength and reduction in systemic inflammation following HSCT in carefully selected patients.
8.14 Inclusion Body Myositis (IBM)
Inclusion body myositis is a slowly progressive inflammatory and degenerative muscle disorder. While HSCT has not shown efficacy for IBM, MSC therapy is being explored for its potential to reduce inflammation and slow muscle degeneration. Early studies suggest modest improvements in muscle function, but further research is needed to establish efficacy.
8.15 Mixed Connective Tissue Disease (MCTD)
Mixed connective tissue disease is an autoimmune condition with overlapping features of lupus, scleroderma, and polymyositis. HSCT has shown potential in severe cases, resetting the immune system and reducing disease activity. Studies report improvement in organ function and symptom relief, though the therapy carries risks and requires careful patient selection.
8.16 Sjögren’s Syndrome
Sjögren’s syndrome is an autoimmune disorder affecting exocrine glands, causing dryness of the eyes and mouth. MSC therapy has shown potential in regenerating salivary gland function and reducing systemic inflammation. Early clinical trials report improved glandular function and symptom relief, though larger studies are needed to validate these findings.
8.17 Polymyositis (PM)
Polymyositis is an autoimmune myopathy causing muscle inflammation and weakness. HSCT is a potential therapy for refractory cases, offering the possibility of long-term remission. Studies indicate improved muscle strength and reduced inflammation in selected patients following HSCT. MSC therapy is also being investigated for its regenerative properties, with early evidence suggesting muscle repair and functional improvement[68-72].
