Stem cell transplantation has emerged as a promising therapy for various immune disorders, offering new hope to patients with conditions that were once considered untreatable. Immune disorders encompass a broad range of conditions where the immune system malfunctions, leading to autoimmune diseases, immunodeficiencies, and other related disorders. Traditional treatments often focus on managing symptoms rather than addressing the root cause of the condition. However, stem cell transplantation presents a revolutionary approach by targeting the immune system itself, aiming to restore its balance and functionality. In recent years, significant advancements have been made in this field, paving the way for more effective and safer treatment options.
