Cell-based therapies bear promise as a means to dampen autoaggressive immune reactions and induce tolerance in patients with severe rheumatic autoimmune diseases. Of the various types of cell-based therapies, immunoablative treatment combined with autologous hematopoietic stem cell transplantation has been used in more than 1000 patients with severe autoimmune diseases worldwide, including patients with rheumatoid arthritis, juvenile idiopathic arthritis, systemic lupus erythematosus, and systemic sclerosis. Long-term improvements of disease activity have been documented, albeit at the expense of treatment-related toxicity and mortality. Based on the results of pilot studies, prospective randomized controlled trials have been initiated to compare safety and efficacy of hematopoietic stem cell transplantation versus conventional treatment. Therapies involving mesenchymal stromal cells are currently being explored in clinical settings because of their anti-inflammatory and tissue regenerative properties and their favorable risk/benefit ratio.

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Satellite Stem Cells and Muscular Dystrophy

Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Stem Cell Therapy for Tissue Regeneration

Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
